Quinton’s Water (often called “marine plasma” or “Quinton marine plasma”) is purified seawater processed and bottled for oral use; it’s rich in naturally occurring major minerals (like sodium, magnesium, calcium) and many trace elements in roughly the proportions found in ocean water. Advocates say that because its mineral profile is broad and present in ionic form, small amounts can help re-establish electrolyte and fluid balance, support cellular hydration, and supply trace nutrients that are otherwise missing in a modern diet. (Quinton Medical)

A common practical claim is that Quinton’s Water can speed recovery after exercise, help with rehydration, and reduce fatigue because of its electrolytes (especially magnesium) and simple bioavailability. Some research on deep-sea water and isotonic seawater suggests potential benefits for physical performance, recovery and aspects of metabolism, so there is a limited scientific basis for the idea that certain types of seawater preparations can support hydration and athletic recovery. However, most of the stronger claims about “restoring all cellular function” go beyond what the clinical literature currently proves. (PMC)

Proponents also point to immunomodulatory and skin-healing effects: small laboratory and product-sponsored reports describe changes in immune cell activity and improvements in skin condition when isotonic seawater is applied topically or used in specific protocols. These findings are intriguing but tend to be preliminary, and many of the positive statements you’ll read come from manufacturer literature rather than large, independent randomized trials. If you’re weighing these as therapeutic claims, it’s fair to treat them as promising but not definitively proven. (Quinton Medical)

On safety and regulation: bottled seawater products vary in concentration (isotonic vs. hypertonic) and sodium content, so people with high blood pressure, kidney disease, or salt-sensitive conditions should be cautious and consult a clinician before use. There is also precedent for contaminated unregulated ocean-water supplements in the past, which led to official warnings, so it’s important to choose reputable, tested brands and to treat any strong medical claims with skepticism. Finally, many product pages include disclaimers that their statements have not been evaluated by regulatory agencies and that products are marketed as supplements rather than medicines. (Gouvernement du Canada)

In short, Quinton’s Water is a mineral-rich seawater supplement that plausibly helps with electrolyte balance, hydration and potentially recovery in some contexts; it has some supportive laboratory and small-scale evidence but not a large body of definitive clinical trials for the broader therapeutic claims. 

Here is a concise summary of what published studies — including small, pilot and product-sponsored studies — have actually found about health effects attributed to Quinton’s Water / marine plasma and related seawater preparations.

Clinical and randomized trials of nasal and upper-respiratory uses consistently show the clearest and most reproducible benefits. Trials and reviews of isotonic and hypertonic seawater or sea-salt saline used as nasal sprays, nasal irrigation or gargles report faster symptom resolution in acute rhinitis, reduced recurrence of rhinitis in children, improved subjective nasal comfort in athletes during intense training, and shorter duration or reduced severity of some viral upper respiratory infections when used early (several randomized or controlled pilot trials and systematic reviews). These effects are the most solidly supported and are generally attributed to mechanical cleansing, improved mucociliary function and local changes in the nasal environment rather than to systemic “remineralization.” (JAMA Network)

A separate body of small clinical work has examined “deep-sea water” or magnesium-rich seawater extracts taken orally and reported metabolic benefits in limited settings. Several randomized or controlled pilot studies and reviews have found that consumption of magnesium-enriched deep-sea water can improve measures of insulin sensitivity in people with pre-diabetes or metabolic disturbances, and some trials reported reductions in total cholesterol and LDL cholesterol after weeks of drinking deep-sea water preparations. These studies are promising for metabolic endpoints (glycemic control and lipid profile) but tend to be small, sometimes short in duration, and often use specific, high-magnesium preparations rather than the diluted isotonic products commonly sold as Quinton’s Water. (PMC)

At the cellular and laboratory level there are mixed findings. In vitro experiments with Quinton isotonic and hypertonic preparations have demonstrated measurable effects on human peripheral blood mononuclear cells (changes in viability, morphology and some proliferation parameters), which supports the idea that marine plasma can alter cell behavior under experimental conditions. Other small lab or pilot cell-culture studies looking for anti-aging or “reconstructive” effects have been inconclusive or failed to reproduce dramatic benefits, showing that laboratory findings do not yet translate into consistent evidence for broad systemic anti-aging claims. (PubMed)

There are also several smaller or device-based studies showing symptomatic improvements when seawater-derived or sea-salt physiological saline sprays are used for nasal congestion, sleep-related breathing complaints and related symptoms in adults; these tend to be pragmatic studies (product or device evaluations) rather than large independent trials, and results are modest but reproducible for symptom relief. Hypertonic saline irrigation and gargling trials have shown reductions in symptom duration for some viral upper respiratory tract infections in pilot randomized work. (PMC)

Across all topics the pattern is the same: small trials, pilot studies and some mechanistic lab work point to real, plausible benefits for (1) local nasal/upper-airway symptom relief and shortened URTI symptoms with topical/isotonic or hypertonic seawater, and (2) possible metabolic effects from magnesium-rich deep-sea water on insulin sensitivity and lipids. However, the evidence is not yet large or uniform enough to support many broader systemic therapeutic claims often made in marketing materials. Many studies use different preparations (isotonic vs hypertonic vs concentrated deep-sea extracts), vary in dose and duration, and in some cases are industry-sponsored, so generalizing results to all “Quinton” products is not justified without attention to the specific formulation used in each study.

Cancer thrives by hijacking the body’s own basic survival systems, making it hard to attack tumors without collateral damage and side effects. Now, researchers at Cornell’s Weill Institute for Cell and Molecular Biology have discovered what may be a less invasive strategy that shows promise as a potential therapeutic pathway. 

New research has uncovered molecules that can preserve crucial cellular processes while blocking malignant proteins from their preferred attachment points on the healthy cell. The findings indicate a new approach to fighting cancer, one that triggers apoptosis – the self-destruct process – in melanoma and bone cancer cells.

The study, published Oct. 6 in the Journal of Medicinal Chemistry, was led by graduate student Nathan Frederick in collaboration with Jeremy Baskin, associate professor and Nancy and Peter Meinig Family Investigator in the Life Sciences in the Department of Chemistry and Chemical Biology in the College of Arts and Sciences, and the Weill Institute for Cell and Molecular Biology. It describes the discovery of the first compounds that directly target a family of proteins called PLEKHA, which help cancer cells grow and spread by interpreting lipid “messages” on cell membranes.

Inside every cell, phosphatidylinositol phosphate (PIP) lipids act like address labels, guiding proteins to the right locations and telling them when to act. Many cancers hijack these signals to keep dividing. Existing drugs that block the enzymes making PIPs can slow tumors but also disrupt vital processes that keep healthy cells functioning – particularly those controlling metabolism, immunity, and the ability for tissues to maintain a stable internal environment. These disruptions then lead to serious side effects, Frederick said.

The team in the Baskin lab flipped the problem around. Rather than turning off PIP production, they aimed to jam the signal receivers – the pleckstrin homology (PH) domains that allow PLEKHA proteins to grab onto lipid molecules. “We wanted to stop the lipid message from being read instead of silencing the entire system,” Frederick said.

Using computer modeling, the researchers screened more than 90,000 drug-like compounds to find those that could fit into the PH domain of PLEKHA4, a protein linked to melanoma growth. They discovered one molecule, called NF1, that bound tightly to the lipid pocket and competed with PIPs for space.

The team then created and tested chemical variations to fine-tune how well the compounds bound PLEKHA both in isolation and within cells. One version, NF14, worked especially well. They found it starts as an inactive “prodrug” that easily enters cells, and then once inside cells it’s converted into NF1 by natural enzymes, activating its cancer-killing potential.

When tested on melanoma and bone cancer cell lines, NF14 disrupted PLEKHA proteins’ grip on the cell membrane, triggering a chain reaction whereby the cells stopped dividing and triggered their own death through apoptotic pathways. Importantly, it showed little effect on cancer cells that make few PLEKHA proteins, suggesting it was hitting its intended target.

A single, gentle move that fits both tai chi and qigong practice and is especially useful for people with eczema or psoriasis is the classic “Wave Hands Like Clouds” (often just called Cloud Hands). It’s simple, low-impact, and designed to open the chest, loosen the shoulders and waist, and gently circulate qi and blood through the upper body—actions that, in TCM thinking, help soothe stuck or agitated “Liver-Qi” (which is often connected to skin flare-ups), calm the nervous system, and reduce the stress that commonly worsens inflammatory skin conditions.

To do it, stand with your feet about hip-width apart, knees soft, spine long and relaxed. Imagine a string pulling the crown of your head upward while your weight shifts slightly from one foot to the other. Hold your arms in front of you at chest height with palms facing each other, fingers relaxed. Move your hands together in a slow, horizontal, circular sweep: one palm opens outward as the other draws inward across your center, while your waist gently turns in the direction of the moving hand. Your eyes can follow the leading hand, and your breathing stays slow and natural—inhale as the hands open or expand, exhale as they come together or cross the center. Keep the motion smooth and continuous, avoiding any tension in the shoulders or neck.

Practically, aim for three to five minutes per session, once or twice a day, or longer if it feels good; even a few slow, mindful minutes before bed can ease itching driven by nighttime agitation. The physical reasons practitioners recommend this move are that it mobilizes the torso and upper limbs (improving local circulation of blood and lymph), relaxes the sympathetic nervous system (lowering stress hormones that can trigger flares), and trains gentle, rhythmic breathing—all of which support skin healing indirectly. From a TCM perspective the waist rotation and open-chest motion “disperse wind” and move constrained qi that can underlie spreading, itchy rashes.

A few cautions: keep the motion soft if you have open, weeping lesions—don’t rub or irritate affected skin, and do the movement more slowly or without arm contact if it stings. Stop if you feel pain, dizziness, or anything unusual. If you’re uncertain how to perform it cleanly, a short class or a video demonstration from a qualified tai chi/qigong teacher can help you learn the correct posture and breathing. In short, Cloud Hands is a low-risk, broadly helpful movement that supports the TCM goal of calming internal agitation and improving circulation—two useful aims for people managing eczema or psoriasis.

Short answer up front: in classical TCM there is no single “one size fits all” herb for eczema or psoriasis because treatment depends on the person’s pattern (damp-heat, blood-heat, wind, dryness, stasis, etc.). That said, if I must name the herb most commonly relied on across many eczema/psoriasis formulas, it would be Ku shen (Sophora flavescens) — and here’s why, explained in TCM terms and supported by modern findings.

Ku shen is widely used in formulas for itchy, oozing, inflamed rashes because, in TCM theory, it clears damp-heat and toxins, dries dampness, disperses wind, and stops itching. Those actions match the typical TCM patterns seen in many eczema and some psoriasis flares (red, weeping lesions, strong itch, crusting or secondary infection). Modern phytochemical research helps explain this choice: Sophora contains active alkaloids (notably matrine and oxymatrine) and other constituents that show anti-inflammatory, antimicrobial and immunomodulatory activity in lab and animal studies — effects that plausibly reduce inflammation, inhibit bacteria (important because staph often worsens eczema), and calm immune overreaction in the skin. For these combined traditional functions and modern signals of activity, Ku shen is often the go-to single herb in clinical formulas and topical preparations aimed at damp-heat eczema. (PubMed)

That said, TCM practitioners will choose other herbs instead of — or alongside — Ku shen when the pattern points elsewhere. For example, Bai Xian Pi (Dictamnus root bark) is frequently selected when the emphasis is clearing heat and dampness from the skin and stopping itching; it’s a classic “detoxify and dry damp” herb for stubborn, crusting rashes and has experimental support for anti-inflammatory, anti-allergic effects. Huang Qin (Scutellaria baicalensis) is another common choice when the picture is strongly “heat” and inflammation; it’s used for cooling and detoxifying and has experimental evidence for improving inflammatory skin lesions. In short, Ku shen is the most broadly useful single herb for many damp-heat/itchy presentations, but Bai Xian Pi or Huang Qin (and others) may be preferable for specific subtypes. (PubMed)

Finally, a few practical cautions. TCM’s strength is tailoring: the same herb can help in one pattern and be unhelpful or even counterproductive in another (for instance, drying herbs can worsen dry-type eczema). Herbs can interact with medications and some people can be sensitive or allergic to them, and quality/preparation matters a lot. So while Ku shen is a reasonable “top candidate” herb for many inflamed, itchy, damp-heat rashes, it’s safest and most effective when prescribed as part of a pattern-based formula by a qualified TCM practitioner (or used in standardized topical products with known safety data). (LearnSkin)

If you’d like, I can summarize the typical TCM patterns for eczema/psoriasis in a paragraph and show which single herb is preferred in each pattern (e.g., Ku shen for damp-heat; Huang Qin for blood/heat; Fang Feng for wind-itch), or I can pull a few research citations that describe clinical/topical uses of Ku shen specifically. Which would you prefer?

(...)  In Traditional Chinese Medicine, eczema and psoriasis are treated by first identifying the pattern causing the skin problem (things called damp-heat, blood-heat or blood-dryness, wind, dryness, or blood stasis) and then choosing herbs that directly counter that pattern. For the common damp-heat pattern — red, oozing, crusted, strongly itchy rashes — the herb most often chosen is Ku shen (Sophora flavescens) because it is classically described to clear damp-heat, dry dampness, dispel wind and stop itching; modern studies also point to active alkaloids in Ku shen (matrine, oxymatrine) that have anti-inflammatory, antimicrobial and immunomodulatory effects, which help explain why it’s frequently used for wet, infected-looking eczema. (ScienceDirect)

When the problem looks more like blood-heat (very red, burning lesions that may bleed) or when the clinical focus is cooling and nourishing blood, herbs such as Sheng di huang (Rehmannia, raw rehmannia root) are favored because they cool the blood and replenish yin fluids, which soothes high-level heat and reduces nocturnal itching and inflammation in blood-heat or blood-dry patterns. This approach fits TCM logic that blood-level heat needs cooling and nourishment rather than drying or strongly draining actions. (PMC)

If the dominant feature is wind — spread-out, migratory, intensely itchy lesions that flare and move, often worse with scratching — practitioners reach for wind-dispersing, anti-itch herbs like Fang feng (Saposhnikovia divaricata) or Jing jie (Schizonepeta). These herbs are traditionally used to “scatter wind” and calm the reflex to scratch; modern descriptions of their use note anti-inflammatory and immune-modulating actions that help reduce the itch-scratch cycle. (learnskin.com)

For stubborn, crusting rashes where the emphasis is on detoxifying the skin and reducing localized inflammation, Bai xian pi (Dictamnus cortex) is a classic pick: it’s indicated for clearing damp-heat and “toxins” from the skin and recent phytochemical work has identified anti-inflammatory constituents that support that traditional use. In practice Bai Xian Pi and Ku shen are often used in similar scenarios, with the choice depending on the precise signs (which area is affected, how much oozing or crusting is present, and whether there is overlapping wind or blood issues). (ScienceDirect)

Finally, when psoriasis shows the common TCM picture of blood dryness or blood stasis (thick, scaly plaques, cracked skin, or long-standing lesions), the approach shifts to herbs that nourish yin and blood or move stasis (for example, Sheng di huang for nourishing and other blood-moving herbs when stasis is present), because drying, strongly draining herbs would worsen a dry-type picture. This is why TCM rarely prescribes a single universal herb: the practitioner selects one herb that best matches the observed pattern and then combines it into a formula that balances the whole person. (PMC)

In short, if you wanted a single “classic” herb name that most TCM clinicians would reach for in many typical, inflamed, weeping eczema cases it would be Ku shen for its damp-heat clearing and anti-itch profile; but different patterns call for different lead herbs — Fang feng for wind-itch, Sheng di huang for blood-heat/dryness, Bai xian pi for toxic damp crusting, and blood-moving/nourishing herbs for stasis or dryness. Because formulas are individualized and herbs can interact with drugs or cause sensitivities, a qualified TCM practitioner is usually consulted to pick the right herb(s) and preparation for a particular patient.

" Wind of the Four Crooks - An atopic Eczema Case Study " summarized by ChatGPT :

The practitioner diagnosed the patient’s eczema as a mixture of wind, dampness, and heat (including “fire toxin”), based on the pattern of signs: intense redness and widespread inflammation (signs of heat), many vesicles and yellow crusting with erosion (signs of damp-heat and toxic exudation), and excoriated scratch marks with lesions concentrated on the face and upper body (features that point to wind). Those pattern observations determined the whole treatment strategy: first clear the heat and toxic dampness that were causing oozing and infection, then, as the dampness was reduced, add herbs that disperse wind and stop the persistent itching. (Pacific College)

The first herbal formula was therefore built around several cooling and heat-clearing ingredients to calm the blood-level heat and remove damp-toxin. The core included Sheng Di Huang (Rehmannia root) and Mu Dan Pi (Moutan bark), which in Chinese herbal logic cool and clear heat at the blood level and help heal inflamed, bleeding or intensely red skin. Paeoniae Rubra (Chi Shao) was included to move and cool the blood, helping inflamed areas recover. A set of bitter and draining herbs such as Long Dan Cao and Huang Qin help clear excessive “liver/fire” and damp-heat from the upper body, while Zhi Zi helps drain fire and reduce high, restless heat that contributes to nocturnal itching. Several herbs with direct anti-toxic or anti-inflammatory properties for the skin — Ma Chi Xian and Zi Hua Di Ding — were used to address the pus, crusting and local infection-like signs. Herbs known specifically to clear damp-heat and relieve itching like Bai Xian Pi were added, plus Xi Xian Cao and Hai Tong Pi which are used to reduce itching and soften hardened or lichenified skin. Fu Ling and Ze Xie were included to promote urination and help expel internal dampness via the urinary tract — an important supporting action because “damp” must be moved out of the body to prevent recurrence. In short, the first prescription targeted cooling, detoxifying, draining damp-heat, and beginning to restore the skin’s normal state. (Pacific College)

When the patient returned after a week, the observed improvement (reduced weeping and lower redness) confirmed that clearing damp-heat was working, and a targeted addition was made: Yin Chen Hao (Artemisiae scopariae) was added specifically for damp eczema in the nipple area. This illustrates a common TCM tactic of starting with a broad formula to treat the dominant, dangerous processes (damp-heat and toxin), then tailoring the mix to local problems as they resolve. (Pacific College)

As the dampness came under control over the following visits and itching diminished, the practitioner adjusted the formula again to emphasize wind-scattering and anti-itch actions. The modified prescription increased the amounts of the cooling herbs (e.g., Sheng Di Huang) but added Fang Feng (a classic wind-dispersing herb) and Bai Ji Li (used to calm itching and stabilize the skin). Lian Qiao (Forsythia) — another herb that clears heat-toxin — and Tong Cao (which assists in venting and promoting fluid movement) were also included, and a small amount of Gan Cao (licorice) was used to harmonize the formula and reduce harshness. This change in emphasis follows a clear logic: once damp-heat and active exudation are reduced, dispersing residual wind (the cause of the restless, spreading itch) and calming the nervous/agitated aspect of the skin becomes the priority. (Pacific College)

Throughout the course the choice and sequence of herbs were guided by ongoing observation: the location of lesions (face/upper body → wind), the presence of vesicles and yellow crusts (dampness and fire toxin), nocturnal itching (heat in the blood), and response to treatment (improvement after damp-heat clearing → safe to add wind-dispersing herbs). The practitioner avoided a single one-size-fits-all approach; instead the treatment shifted from aggressive clearing of damp-heat/toxin toward more balancing, anti-itch and restorative herbs as the clinical picture changed. (Pacific College)

In plain terms: the therapy began by cooling and detoxifying the blood and skin while drawing out the internal dampness that was feeding the oozing, inflamed patches. Once that dangerous, active inflammation and moisture were under better control, the formula was adjusted to focus on stopping the wind-like spreading itch and consolidating the skin’s recovery. Each herb was selected for a specific role in that sequence — cooling, draining, detoxing, dispersing wind, or calming itch — and the physician altered the recipe as the patient improved, which is typical of individualized TCM herbal care.

The article "Insights from Traditional Chinese Medicine for Restoring Skin Barrier Functions" explains that your skin isn’t just a cover — it’s an active, smart barrier whose job is to hold in moisture and keep out things that can harm you, like germs, irritants and allergens. When that barrier is damaged, the skin becomes dry, itchy and inflamed, and people are more likely to get flare-ups of conditions such as eczema or psoriasis and even infections. The review looks at a wide range of substances used in Traditional Chinese Medicine (TCM) — plant and fungal extracts, and the chemical components inside them — and shows how many of these substances appear to help the skin rebuild and protect that barrier.

Instead of acting in one single way, these TCM-derived ingredients seem to help on several fronts at once. Some calm down inflammation so the skin stops reacting wildly and feeling hot or itchy. Others act like antioxidants, neutralizing damaging molecules that break down cells and slow healing. A number of compounds encourage skin cells to grow, mature and stick together in the right way so the outer layer becomes stronger. There are also ingredients that help the skin restore the natural fats (like ceramides) that lock moisture in, and a few that change the mix of microbes on the skin toward a healthier balance. The combination of these effects — less inflammation, less cell damage, improved cell renewal, and better lipid content — is exactly what the skin needs to mend its barrier and stay hydrated and comfortable.

The paper gives concrete examples: chemicals found in ginseng (ginsenosides), many plant flavonoids, certain alkaloids and long sugar molecules called polysaccharides all show useful actions in laboratory and animal studies. A handful of human studies are mentioned too — for example, small trials where red ginseng extract improved symptoms in people with atopic dermatitis, and studies where oxymatrine (an alkaloid) showed benefit in psoriasis. Those human results are encouraging but limited: the trials tend to be small, use different preparations and doses, and are not yet consistent enough to be taken as definitive proof that a given herb will help everyone.

One practical point the review raises is that how an ingredient is delivered matters a lot. Some of these natural molecules don’t penetrate the skin well or are unstable, so modern formulations (creams designed to get the active stuff into the right layer, or tiny carrier systems) can make a big difference in whether they actually work. The authors also stress caution: “natural” does not automatically mean safe for every person. Herbal products vary in strength and purity, can trigger allergic reactions in some people, and different studies use different preparations, which makes it hard to compare results across trials.

Overall, the message is hopeful but measured. A large body of laboratory work and animal studies shows clear ways that TCM ingredients can support barrier repair, and a few human studies suggest real benefit in people with inflammatory skin problems. However, the human evidence is still patchy and more large, well-designed clinical trials are needed to know which ingredients help which conditions, at what dose, and in what form. For someone with everyday dryness or mild inflammation, products containing some of these extracts might help as part of a skincare routine. For people with moderate to severe eczema or psoriasis, these herbal options are best considered complementary to proven medical treatments and discussed with a dermatologist before switching or stopping prescribed therapies.

In traditional Chinese medicine the term “extraordinary vessels” (also called extraordinary meridians) names a group of deep, largely unpaired channels that differ from the twelve primary meridians in both function and trajectory. Where the primary meridians circulate qi and blood to the limbs and organs on a daily basis, the extraordinary vessels act as storage and regulatory systems: they receive, hold, transform and redistribute the body’s deeper substances (essence, blood and constitutional qi) and they modulate the activity of the primary channels. Because of this reservoir-like role they are often described as the body’s constitutional or structural network — less about day-to-day circulation and more about long-term balance, development, and resilience.

Classically there are eight principal extraordinary vessels. Four of them—the Conception Vessel (Ren, 任脉) and the Governing Vessel (Du, 督脉) plus the Penetrating or Chong Vessel (冲脉) and the Girdling or Dai Vessel (帶脉)—are frequently emphasized for their central roles in reproduction, growth, the axis of the trunk, and the circulation of blood and qi through the torso. The other four—two Motility (Qiao) vessels (Yin Qiao, 阴跷; Yang Qiao, 阳跷) and two Linking (Wei) vessels (Yin Wei, 阴维; Yang Wei, 阳维)—function more as lateral regulators of activity, posture, sleep/wake cycles, and the integration of emotional and defensive responses. These names and roles come from many centuries of observation and were developed in classical texts and the clinical tradition; they describe functional networks rather than one-to-one anatomical structures.

Because extraordinary vessels are closely tied to congenital substance and deep physiological reserves, they are strongly implicated in issues of constitution, development, reproductive and gynecological disorders, chronic disease, and conditions that resist ordinary treatment. For example, the Chong is often called the “sea of blood” because of its relationship to menstrual and reproductive function; the Ren and Du are seen as central vertical axes that govern yin and yang respectively; the Dai constrains the flow around the waist and can be implicated in patterns of bloating, hernia-like sensations, or deranged flows; and the Qiao and Wei vessels influence mobility, the alternation of sleep and waking, and certain patterns of emotional reactivity. Clinically, acupuncturists and herbalists use points and protocols that target these vessels when a problem appears structural, constitutional, chronic, or when the twelve primary channels alone do not restore balance.

Mechanistically, the extraordinary vessels are considered to interact with the kidneys, the stores of essence, and with the yuan (source) qi that supports all other functions. They are sometimes described as “reservoirs” because they accept overflow from the primary meridians and release it when needed, helping to buffer and integrate physiological change. They also form developmental pathways: many of the extraordinary vessel theories explain life stages, aging, fertility and the transmission of inherited tendencies, which is why they are emphasized in congenital or long-standing disorders.

In practice these vessels are engaged through specialized acupuncture techniques, needling of particular points that connect to the extraordinary network, moxibustion, and longer-term constitutional therapies. It’s important to understand that extraordinary vessels belong to a medical model distinct from modern anatomy; they are best read as functional and relational maps for diagnosis and treatment rather than as literal blood vessels or nerves. For students and patients this means extraordinary-vessel work is especially useful when treating deep-rooted, constitutional, developmental or chronic patterns that require more than symptomatic or surface-level intervention.

Here are a few well-sourced quotes about the extraordinary vessels, each with a short line of context and a citation so you can follow the original text.

“The sages built ditches and reservoirs and they kept the waterways open in order to be prepared for above-normal situations. When there are heavy rains, ditches and reservoirs are full to the brim… in the human body, when the channels are over-filled they cannot absorb the excess [and this overflow from the main channels is absorbed by the extraordinary vessels].”
— Nan Jing (Classic of Difficult Issues). (dokumen.pub)

“When the Qi of the channels overflows, it flows into the extraordinary vessels where it is turned into irrigation, warming the organs internally and irrigating the space between skin and muscles externally.”
— Li Shízhēn, quoted in modern commentary on the Eight Extraordinary Vessels (summarizing classical thinking about their ‘reservoir’ function). (giovanni-maciocia.com)

“The Chong Mai is called the ‘Sea of Blood’… it is said to be able to treat blood stagnation anywhere in the body.”
— classical/traditional description frequently cited in texts on the extraordinary vessels (used to explain the Chong’s relationship to blood, reproductive and constitutional functions). (acupuncturetoday.com)

“The Extraordinary Vessels act as reservoirs of energy in relation to the main channels, which are compared to rivers.”
— Giovanni Maciocia (modern textbook summary of classical sources). (giovanni-maciocia.com)

In traditional Chinese medicine (TCM) the terms pre-heaven qi (先天气, xiāntiān qì) and post-heaven qi (后天气, hòutiān qì) describe two related but different sources of the body's vital substance. Pre-heaven qi is the congenital, inherited component you receive at conception from your parents. It is closely tied to your constitutional strength and to what TCM calls jing (essence). This congenital qi is thought of as relatively fixed—your basic vitality, growth trajectory, and constitutional tendencies come from it—and it is often associated with the Kidneys as the storehouse of that inherited essence. When pre-heaven qi is abundant, a person tends to have stronger resistance, better development and longevity on a constitutional level; when it is weak, the person is more vulnerable to chronic problems that are hard to shift.

Post-heaven qi, by contrast, is the qi produced and replenished after birth from everyday life: the qi extracted from food and drink by the Spleen and Stomach and the qi taken in with the breath by the Lungs. It is sometimes called acquired qi because it depends on what you eat, breathe, how well you sleep, and how you live. Post-heaven qi is much more changeable than pre-heaven qi—poor diet, stress, lack of sleep, or chronic illness can deplete it, while good nutrition, regular exercise, rest, and breathing practices can strengthen it. Clinically in TCM, many treatments aim to support or restore post-heaven qi so it can in turn support the deeper, constitutional functions (and slow the depletion of pre-heaven reserves).

Is there something “between” them? TCM doesn’t usually place a strict third category sitting halfway between the two, but it does describe intermediate or linking forms of qi that bridge congenital and acquired sources. Two important examples are Yuan qi (原气, “original” or “source” qi) and Zong qi (宗气, “gathering” or “ancestral” qi). Yuan qi is often described as the expression of pre-heaven qi that acts as a foundation for all other functional activities; it originates from congenital essence but needs nourishment from post-heaven qi to manifest fully. Zong qi is formed from the combination of the pure aspects of air (from the Lungs) and food qi (from the Spleen/Stomach) and gathers in the chest to assist breathing and circulation—so it’s very much a product of post-heaven processes but also helps support the whole system. In practical terms these intermediary categories explain how the “fixed” inheritance and the “renewable” daily supply interact: you can’t change your inherited baseline easily, but by building strong post-heaven qi you can bolster Yuan qi’s function and preserve pre-heaven reserves.

In short, pre-heaven qi is your inherited constitutional vitality, post-heaven qi is the continuously produced, daily energy from food and breath, and concepts like Yuan qi and Zong qi act as functional bridges between them. The clinical implication in TCM is important: while you can’t easily increase what you were born with, you can actively care for and strengthen post-heaven qi—through diet, rest, mindful breathing, and lifestyle—so it supports and preserves your deeper, pre-heaven resources.

Here are a few thoughtful and relevant quotes that beautifully echo the ideas behind pre-heaven and post-heaven qi—the balance between what we inherit and what we cultivate:

“Life is the gathering of qi; when qi gathers, there is life. When qi disperses, there is death.”
— Zhuangzi (4th century BCE)

This foundational line expresses how qi—whether inherited (pre-heaven) or acquired (post-heaven)—is the essence of all vitality and transformation.

“Heaven bestows the form; Earth nourishes the shape. The union of Heaven and Earth gives birth to Man.”
— Huangdi Neijing (The Yellow Emperor’s Inner Classic)

This describes the interplay of pre-heaven (Heaven’s endowment) and post-heaven (Earth’s nourishment), emphasizing that human life is born from both inheritance and environment.

“Essence is the root of the body; qi is its function. When essence is sufficient, qi flourishes; when qi is strong, essence is preserved.”
— Huangdi Neijing Suwen, Chapter 1

This quote captures the dynamic relationship between jing (the pre-heaven essence) and qi (especially post-heaven qi), showing how one supports and protects the other.

“Though one’s destiny is fixed by Heaven, cultivation refines what Heaven has given.”
— Daoist saying, attributed to the Taiping Jing (Scripture of Great Peace)

A poetic expression of the idea that even though pre-heaven qi is inherited, we can refine and sustain it through conscious living—by nurturing post-heaven qi through breath, food, and practice.

Human sexuality is closely linked to the physiology and pathology of the extraordinary vessels, especially the Du, Ren and Chong Mai. The Du and Ren Mai are the expression of Fire and Water respectively with regard to sexuality: the exchange of sexual essences and of Yin and Yang during sexual intercourse takes place through the intertwining of the Du and Ren Mai during intercourse. Both these vessels arise from the space between the Kidneys where the Yuan Qi throbs: they then flow down to the perineum where they separate, one following the spine up to the brain, the other following the front up to the face and eyes.  However, internally they intersect and both flow through the heart. The “Su Wen” in chapter 60 has the following pathway for the Du Mai: it starts near the uterus, goes down to the pubic bone, in women to the vagina.  Its Luo channel goes around the vagina, passes to the perineum, then the buttocks, down to meet the Kidney and Bladder channels inside the upper thighs; it then rises up the spine and wraps around the kidneys.  In men it goes around the penis and then the perineum.  We can therefore see that the Du Mai flows to the genitals and is therefore stimulated by sexual intercourse. Chapter 60 of the Su Wen also describes an abdominal branch of the Du Mai that starts in the abdomen, goes up to the umbilicus, past the heart, throat, chin, around lips and reaches the eyes.

Some see this “main vessel” as being the Ren Mai.  In fact, what it means is that the Du and Ren Mai are almost like two branches of the same vessel, one Yang and one Yin, intersecting inside.  Li Shi Zhen says: “The Du and Ren Mai are like midnight and midday, they are the polar axis of the body…there is one source and two branches, one goes to the front and the other to the back of the body…we can make connections between them.  When we try to divide these, we see that Yin and Yang are inseparable.  When we try to see them as one, we see that it is an indivisible whole.” Wang Big considered this “main vessel”, not as the Ren Mai but as a branch of the Du Mai flowing with the Ren Mai: “Another branch [of the Du Mai] starts in the lower abdomen, comes up the abdomen, to the centre of the eyes, following the pathway of the Ren Mai.  This is why we can say that the Du, Ren and Chong Mai have different names, but are all the same.” Thus, the Du Mai embodies the Minister Fire and the Ren Mai Water: the contact of the penis inside the vagina establishes the link between the Du and Ren of the man and woman and therefore the exchange of Yin and Yang sexual essences between them.  Moreover, if the partners also kiss simultaneously, the communication between the Du and Ren is established not only below but also above as the Du Mai ends on the upper gum and the Ren Mai flows to the mouth, thus completing the circle.
The three dan tians are of course closely linked to the Du and Ren Mai.

Upper Dan Tian: this is variously identified as the point Yintang, Du-20, a point between the eyes, the centre of the brain called “ni wan” or the centre of the chest.  In any case, all these points are either on the Du or the Ren Mai.
Middle Dan Tian: on the Ren Mai, Ren-12.
Lower Dan Tian: generally below the navel, could be Ren-6, Ren-5, Ren-4.  There are actually three Dan Tian on the same level: one anterior on the Ren, one in the middle on the Chong and one posterior on the Du (Du-4).

Some sex manuals give three different locations for women:

Upper Dan Tian: the breasts.
Middle Dan Tian: the navel itself.
Lower Dan Tian: the uterus.

The three passes are also along the Du Mai; they are like energetic bottlenecks through which Qi has to pass in its ascent to the brain.  The lower pass is at the coccyx; the middle is in the middle of the thoracic vertebrae; the upper is at the occiput.

The nine orifices in sex manuals are different than the usual ones (eyes, ear, etc.): they are the three dans tians, the three passes and the three points: these last three are Du-20, Ren-1 and the point called niwan (centre of the brain).  The three dan tians, three passes and three points form a circuit which is activated during sexual intercourse. In the pre-natal life, the Du and Ren are connected, whilst after birth, they are severed.  The connection can be re-established through two “magpie bridges”, in the mouth (holding pressing the tongue upwards on the palate) and in the anus (by contracting the anal sphincter).  Both these manoeuvres are effected during Ba Gua exercises and the first during Tai Ji Quan and Xing Yi. The Three Peaks are also related to the Ren and Chong vessels.  The Three Peaks are the mouth, breast and vagina in a woman: during intercourse, the man can absorb a nourishing Qi and fluids from these three peaks.  The upper Peak is called Red Lotus Peak and its medicine is called Jade Fountain; the middle Peak is called the Double Lotus Peak. And its medicine is called the Peach of Immortality; the lower Peak is called Peak of Purple Agaric of Grotto of the White Tiger or Mysterious Gateway and its medicine is called White Lead or Moon Flower. The mouth is related to both Ren and Chong Mai, the breast to the Chong and the vagina to the Ren Mai.  It should be clarified here that the man absorbs the vaginal secretions not through fellatio but through his penis. The Kidneys and the Ren Mai are related to the salivary glands: the Qi of the Kidneys is stimulated during sexual intercourse, it rises in the Du Mai, flows into the mouth and is transformed into sweet salivary elixir.  For this reason, absorbing the woman’s energy and fluids from the Upper Peak is particularly beneficial.
