Hai Tong Pi (Indian Coral Tree Bark)

Q: How do you choose raw versus prepared? Can Wu Jia Pi replace it?

It is cut into pieces and used raw. Wu Jia Pi leans to strengthening sinews without specialized parasite-killing, so it cannot replace Hai Tong Pi by equal weight. Commercial products follow regulated processing; do not self-modify.

What Is Hai Tong Pi?

Hai Tong Pi (海桐皮; Hǎi Tóng Pí; Latin: Erythrinae Cortex; English: erythrina bark) in the current pharmacopoeia is the dried bark of the coral tree Erythrina variegata, or the arbor coral tree, of the Fabaceae family — a deciduous tree with conical sharp thorns on its trunk and branches — harvested in summer or autumn, when the bark peels easily, usually used raw after impurities are removed, washed, cut into strips, and dried. It is neutral, bitter, and acrid, enters the Liver and Kidney channels, and its core actions are to dispel wind-damp and unblock the channels, and to stop pain and dry damp for itch. It usually goes into decoctions, light teas, or warm washes. The usual amount is 5–10 g; a home cup of tea uses a milder 3–5 g. It needs no pre-decocting, late addition, or wrapped boiling — soaked half an hour first, then simmered twenty to thirty minutes. External use is a suitable amount of strong decoction, cooled to warm, washed over itchy skin and aching joints.

It is not Wu Jia Pi. Wu Jia Pi (Acanthopanax Bark) is warm, acrid, and bitter, suiting cold-damp bi while also tonifying the liver and kidney and strengthening the tendons and bones; this coral tree bark is neutral, leaning to unblocking channels and stopping pain when there is no clear cold or heat. Heat bi, with red swollen hot joints, is a poor match. Use caution in pregnancy and breastfeeding. Broken, oozing skin lesions should not be washed with it on your own. Blood-deficiency dry itchy skin needs nourishing first, not this drying bark. Anyone allergic to Fabaceae plants should skip it. Do not keep brewing it daily for more than a few days at a stretch.

It is used most often for three patterns:

Wind-damp bi — aching heavy joints, worse on rainy days, numbness, limited movement
Waist-leg soreness from long sitting or standing, calf tightness and cramping
Damp skin itch — eczema rashes, scabies, or ringworm with scaling and itching

Bitter, acrid, and neutral, it is not a daily “joint opener” tea to keep brewing. A scattering, drying bark with no wind-damp blockage present consumes fluids and irritates a weak stomach.

When wind-damp blocks the channels of the limbs, or damp-toxin gathers on the skin, aching tight joints and itchy rashes are common. Hai Tong Pi is neutral, bitter, and acrid. It dispels wind-damp, unblocks the channels, dries damp, and stops itch, which is why it appears in Hai Tong Pi Tang (Erythrina Bark Decoction)–type formulas. It unblocks more than it tonifies. A heat-type red swollen joint, or blood-deficiency dry skin, gets worse if more is added.

Hai Tong Pi is not a catch-all joint pain bark. In heat-type bi, with red hot swelling, or in pregnancy, using it alone is a poor match. Raw cut or washed clean, and whether it belongs in a formula, should be decided by a licensed Chinese medicine practitioner after pattern diagnosis.

Hai Tong Pi: Materia Medica Profile

Identification & Quality Standard

Erythrinae Cortex

Botanical Origin

The dried bark of Erythrina variegata L. var. orientalis (L.) Merr. or Erythrina arborescens Roxb. (Fabaceae).

Production Regions

Primarily produced in the Chinese provinces of Guangdong, Guangxi, Yunnan, Hainan, Fujian.

Quality Requirements

Superior material is thick, with large, hard prickles.

Macroscopic Features

Irregular half-cylindrical or plate-shaped pieces, 10~20 cm long, 1~2 cm thick; externally brownish-black or dark brown, rough, with sharp conical prickles up to 8 mm high, the prickle base 1~3 cm diameter; inner surface yellowish-brown, smooth with fine longitudinal striations; texture hard and brittle; fractured surface fibrous; slight odor; bitter taste.

Main Regions and Quality Identification

Traditional materia medica and industry experience value the Fujian, Guangdong, and Yunnan producing regions, though actual quality also depends on variety, harvest time, processing, and storage. Fujian's Ci Tong bark, with its longer growth cycle, is thick and rather hard; Guangdong's Hai Tong Pi, with the warmer climate, is relatively thinner. The raw product looks light brown to deep brown, with longitudinal cracks, residual thorns visible on the surface, a tough texture, a fibrous cut face, a faint green-grass scent, and a slightly bitter taste. The processed form differs little from the raw — mainly cut into strips or pieces for easier decocting. Common look-alikes are barks of other thorny plants, such as the Rutaceae Ci Huang Bai — its surface thorns are flatter and rounder, the cut face leans more toward cork layer, and the odor differs from Hai Tong Pi — distinguish them carefully.

1. Records in Classic Materia Medica

Shen Nong Ben Cao Jing: not clearly recorded.
Ming Yi Bie Lu: its earliest medicinal record — "treats cholera, miasma, qi, dysentery, red-white, and long-term diarrhea" — this mainly points to its qi-moving, damp-drying action, with an extended link to the later joint effects.
Xin Xiu Ben Cao: "treats failure of the waist and legs, stubborn Bi, leg-knee pain, cholera, red-white dysentery, bloody dysentery, and scabies-tinea" — explicitly noting its action on waist-leg joint pain.
Ben Cao Gang Mu: adds — "Hai Tong Pi can move through the channels, reach the disease site, and also enter the blood level, dispelling wind and killing parasites."
De Pei Ben Cao: records the pairings — "with Niu Xi, treats waist-knee pain; with Wu Jia Pi, treats wind-damp Bi."

2. How Views of Its Nature Changed

Different physicians saw it differently. Early physicians focused more on its qi-moving, damp-drying, and anti-diarrhea actions — the Ming Yi Bie Lu record leans toward gastrointestinal regulation. By the Tang-era Xin Xiu Ben Cao, physicians began focusing on its joint-pain action, using it for waist-leg failure and Bi pain. In the Ming era, Ben Cao Gang Mu emphasized its channel-freeing and parasite-killing effects, widening its scope. Some physicians held that it leans toward freeing and suits excess damp-stagnation joints; others held that it is neutral and not harsh, usable for mild Bi pain mixed with deficiency and excess. These differences show that Hai Tong Pi must be matched to the specific pattern — it is not for every joint problem.

Core Efficacies & Traditional Applications

Traditional Functions

Dispels wind-dampness, unblocks collaterals, stops impediment pain, and kills parasites and relieves itching.

1. First Direction: Dispelling Wind-Damp and Freeing the Channels

Traditional action: dispel wind-damp, free the channels, and stop pain — clearing the damp in the channels and easing the soreness, numbness, tightness, or pain of limbs and joints.
Typical signs: the Bi pattern from wind-damp blocking the channels — joint pain that worsens on rainy days, limited limb movement; or the mild-to-moderate modern discomfort of sore heavy waist and legs and calf cramps from long sitting, long standing, or air conditioning.
Usual combinations: often paired with Du Huo and Fang Feng to strengthen the wind-damp-dispelling effect, or with Niu Xi and Ji Xue Teng to strengthen channel-freeing and pain-stopping.
Who should not self-use: heat-Bi patients with marked red, swollen, hot, painful joints — usually damp-heat blockage; Hai Tong Pi's neutral-drying nature may worsen the heat. Pregnant women should also not self-use; use under a doctor's guidance.

2. Second Direction: Drying Damp, Killing Parasites, and Stopping Itching

Traditional action: dry damp, kill parasites, and stop itching — removing surface damp and parasites and easing skin itching and rashes.
Typical signs: skin problems from damp or insect toxin — eczema, scabies-tinea itching, rashes, scaling.
Usual combinations: often paired with Ku Shen and Bai Xian Pi to strengthen the damp-drying, itching-stopping effect, or with Di Fu Zi to strengthen wind-dispelling and itching-stopping.
Who should not self-use: those with broken skin and marked exudate — Hai Tong Pi may irritate the wound and worsen the discomfort; nor is it suited alone for dry-skin itching from blood deficiency with wind-dryness — that pattern needs blood-nourishing and moisture-restoring, and Hai Tong Pi's drying may worsen the dryness.

3. Classic Pairing: Hai Tong Pi With Niu Xi

The classic herb pair is Hai Tong Pi with Niu Xi. Niu Xi tonifies the liver and kidney, strengthens the sinews and bones, and guides the medicine downward — directing the action to the lower-limb joints. Together, Hai Tong Pi and Niu Xi strengthen the channel-freeing, pain-stopping effect while also covering liver-kidney insufficiency — suiting the pattern of waist-leg Bi pain and lower-limb tightness. This is a coordinating relationship: Niu Xi's tonifying restrains Hai Tong Pi's drying (so it doesn't harm the yin), and Hai Tong Pi's freeing helps Niu Xi do its work better. Note that this pairing needs a practitioner's pattern diagnosis — not every waist-leg discomfort suits it; for example, damp-heat Bi pain patients should not use it.

Modern Research

Modern research offers useful context, but Traditional Chinese Medicine prescribes on whole-pattern diagnosis rather than isolated compounds.

1. Main Chemical Constituents

Detected constituents include alkaloids, flavonoids, terpenoids, and coumarins — among them erythrinine is a more studied alkaloid, a naturally occurring compound in the plant. In vitro, some studies observed that the extract inhibits the activity of certain inflammatory factors — but this is a lab-environment result, not the effect of direct human use. In animal experiments, animals given the extract showed some reduction in joint swelling — but this is an observation at specific doses in animal models and cannot be directly equated with human treatment effects. There is not yet sufficient human clinical research to reach clear conclusions on Hai Tong Pi's effects on joints or other symptoms in people.

2. Current Research Directions

Current work centers on its anti-inflammatory and analgesic potential. Some in vitro experiments observed that the extract regulates inflammation-related signaling pathways; animal experiments also observed reduced pain responses. However, most of this research is at the basic stage — more human studies are still needed to verify the actual actions and effective doses in people. Lab results cannot be equated with clinical effects.

3. Limitations of Current Research

Lab results are not clinical efficacy — in vitro and animal results cannot be directly applied to humans; the human physiological environment is far more complex than the lab environment.
Extracts and monomers are not the same as traditional decoction pieces — experiments use high-concentration extracts or single components, while daily use is the soup decocted from slices; the active-component content and absorption differ.
Methods and doses vary between studies — differences in dose and preparation lead to differing results that cannot form a unified conclusion.
A single component does not define the whole herb — Hai Tong Pi works through many components together; one component's action cannot represent the whole herb's effect.

Comparing Similar Herbs

1. What They Share

Hai Tong Pi and the similar-acting Wu Jia Pi share three main points:

Both have dispelling wind-damp, freeing the channels, and stopping pain as a main action — both ease the soreness and pain of limbs and joints.
Both are used for the Bi pattern from wind-damp blocking the channels — whether the ancient Bi pattern or modern limb discomfort, both have some regulating effect.
Both need constitution and dose care — not everyone suits long-term use; daily use should control the dose to avoid overuse.

2. The Key Differences: Hai Tong Pi vs. Wu Jia Pi

Nature and flavors: Hai Tong Pi is neutral with pungent-bitter flavors; Wu Jia Pi is warm with pungent-bitter flavors. Hai Tong Pi's neutrality suits damp stagnation without a clear cold-heat lean; Wu Jia Pi's warmth suits heavier cold-damp, warming and scattering the cold.
Focus: Hai Tong Pi focuses more on freeing the channels and stopping pain — aimed at limb tightness and pain from channel blockage, especially freeing channel stagnation; Wu Jia Pi, besides dispelling wind-damp, also tonifies the liver and kidney and strengthens the sinews and bones — leaning toward nourishing, suiting wind-damp with liver-kidney insufficiency.
Qi tendency: Hai Tong Pi leans toward scattering and draining — mainly freeing the damp and qi blockage in the channels, draining-first; Wu Jia Pi leans toward warm-tonifying — both dispelling wind-damp and tonifying the liver and kidney, tonify-and-drain together.
Best fit: Hai Tong Pi suits limb soreness and numbness that worsen in damp, without clear cold-heat signs; Wu Jia Pi suits joint pain accompanied by weak sore waist and knees, sinew-bone weakness, and a fear of cold — the cold-damp or liver-kidney-insufficiency signs.
Not suitable: Hai Tong Pi is not for heat-Bi patients with red, swollen, hot, painful joints, nor for blood-deficiency patients with dry, itchy skin; Wu Jia Pi is not for yin-deficiency-fire patients — who already have a dry mouth, tidal heat, and night sweats; its warmth may worsen the yin deficiency.
Use scenes: Hai Tong Pi is used more for daily limb-discomfort regulation — waist-leg soreness after long sitting, mild joint tightness — and externally for skin itching; Wu Jia Pi is used more where tonifying is also needed — elderly weak waist and legs, wind-damp Bi with liver-kidney insufficiency, or daily care that nourishes the sinews and bones.

3. One-Sentence Summary

Simply put, Hai Tong Pi leans toward freeing the channels and easing limb soreness and tightness, whereas Wu Jia Pi leans toward dispelling wind-damp while tonifying the liver and kidney and strengthening the sinews and bones. Both can be used for wind-damp Bi pain, but they are not interchangeable.

Classical Formulas Containing Hai Tong Pi

Classic Formula 1: Hai Tong Pi Tang (Erythrina Bark Decoction)

Hai Tong Pi Tang is a classic formula from the Yi Zong Jin Jian.

Combination logic: Hai Tong Pi is the lord, playing the core role of dispelling wind-damp, freeing the channels, and stopping pain; it is combined with Tou Gu Cao, Ru Xiang, and Mo Yao — Ru Xiang and Mo Yao activate blood and stop pain, Tou Gu Cao strengthens the channel-freeing effect — plus blood-activating herbs such as Dang Gui and Chuan Xiong, working together to strengthen the channel-freeing, pain-stopping effect. The formula mainly addresses limb joint pain and tightness from wind-damp blocking the channels, or stasis pain in the limbs after traumatic injury. It needs several herbs working together — Hai Tong Pi cannot be used alone, because a single herb cannot cover blood-activating, channel-freeing, and pain-stopping at once.

Traditional use: traditionally used for limb pain and limited movement from traumatic injury and wind-damp Bi pain.

Modern note: modern clinical use requires a doctor's pattern diagnosis and standard care; do not self-apply just because the formula name relates to a condition — for a traumatic injury, first confirm the degree of injury, then let a doctor judge whether the formula fits.

Classic Formula 2: Hai Tong Pi San (Erythrina Bark Powder)

Hai Tong Pi San is a formula from the Yang Shi Jia Cang Fang.

Combination logic: Hai Tong Pi is the lord, combined with Niu Xi, Qiang Huo, and Gui Xin — Niu Xi guides the medicine downward, Qiang Huo dispels wind-damp in the upper body, Gui Xin warms and frees the channels — working together to strengthen the wind-damp-dispelling, channel-freeing effect. The formula mainly addresses waist-leg pain and limited lower-limb movement in the Bi pattern, especially waist-leg discomfort from wind-damp with cold. Again, several herbs must work together to cover wind-damp and cold in both the upper and lower body.

Traditional use: traditionally used for waist-leg pain and lower-limb tightness from wind-damp Bi pain.

Modern note: modern clinical use requires a doctor's pattern diagnosis and standard care; do not self-use — patients with chronic conditions such as high blood pressure or diabetes especially need a doctor's evaluation first.

Formulas vs. Single Herbs

A formula works through many herbs together — the lord, minister, assistant, and courier combination covers several disease mechanisms to achieve an overall regulating effect. A single herb cannot simply replicate a full formula's effect, because one herb cannot cover the formula's multiple actions — for example, the blood-activating, pain-stopping, and channel-freeing actions in Hai Tong Pi Tang cannot be fully achieved by Hai Tong Pi alone. The formula's doses and combinations are holistic — every herb's amount and pairing is considered to reach the best synergy; adjusting doses or pairings on your own may affect the effect or even cause discomfort. And be clear: that a herb works inside a formula does not mean taking it alone will work the same way. In daily regulation, if you use Hai Tong Pi, do so under a doctor or pharmacist's guidance and fit it to your own situation — don't directly copy the single-herb use from a formula.

Diet & Daily Home Use

1. Home Tea

Tea — Hai Tong Pi Sang Zhi Cha: Hai Tong Pi slices 5 g, Sang Zhi 10 g, Sheng Jiang 2 slices. Wash all the ingredients, put them in a teapot, steep in boiling water for 10 minutes, and drink; can be re-steeped until the taste fades. Suited to the waist-leg soreness, calf tightness, or mild joint discomfort from long sitting, long standing, and air conditioning — for daily regulation, 2–3 times a week. Not for: heat-Bi patients with red, swollen, hot, painful joints, pregnant women, and blood-deficiency patients with dry, itchy skin — drinking it may worsen the discomfort. Note: Hai Tong Pi is a medicinal decoction piece and cannot be used directly as an ordinary food — choose properly processed slices from a regular pharmacy, and avoid the bark of wild plants, for safety.

2. Decoction and Processing Differences

The raw and processed forms differ little. The raw product is tough and needs a somewhat longer decocting time; processed products are cut into strips or pieces and release the active components more easily. Hai Tong Pi has no special decocting requirement — no pre-boiling, late addition, or bagging. At home: wash the slices, put them in a pot with water, soak for 30 minutes, bring to a boil on high heat, then simmer 20–30 minutes. Different forms cannot be converted directly — the tea dose is a small daily-regulation amount; if used medicinally, the dose needs adjusting and requires a doctor's prescription.

3. Dosage and Course

The common dose in traditional prescriptions is 5–10 g; the tea dose for daily regulation is 3–5 g; food-therapy doses run 5–8 g; medicinal doses follow the doctor's advice. The difference between food and medicinal doses: food doses are smaller, for regulating mild daily discomfort; medicinal doses are larger, for marked symptoms. Long-term continuous use is not advised: in daily regulation, use 3–5 days, then rest 2–3 days, to avoid overuse. Special groups — pregnant and breastfeeding women, children, and people with liver or kidney impairment — should consult a doctor or pharmacist before use and not self-use.

Contraindications & Safety Warnings

1. Who Should Avoid It

Heat-Bi patients — red, swollen, hot, painful joints; usually damp-heat blockage, and Hai Tong Pi's drying may worsen the heat signs.
Pregnancy and breastfeeding — there is not enough safety data yet; do not self-use.
Children and the elderly — special constitutions; adjust the dose and have a doctor evaluate first.
Liver or kidney impairment — drug metabolism may be affected; use cautiously.
Allergy to Fabaceae (bean-family) plants — Hai Tong Pi belongs to the bean family; it may trigger an allergic reaction.
Those on anticoagulant, blood-pressure, or blood-sugar medications — consult a doctor before use to avoid interactions.

2. Interactions and Diet Notes

Hai Tong Pi may interact with anticoagulants, affecting their anticoagulant effect — patients on anticoagulants should consult a doctor; it may also have a mild effect with blood-pressure and blood-sugar medications, so monitor blood pressure and blood sugar changes. There is no sufficient evidence for a general "food clash" between ordinary foods, but certain herbs can interact with specific drugs — anyone on medication should consult a doctor or pharmacist first and avoid pairing Hai Tong Pi with other drugs or food-therapy recipes on their own. In daily diet, no ordinary food needs to be avoided deliberately — a balanced diet is enough.

3. Adverse Reactions and Overdose Risk

Overdose may bring gastrointestinal discomfort — nausea, vomiting, diarrhea — and some people may have allergic reactions such as rash and itching. If marked discomfort, allergy signs, persistent vomiting, breathing difficulty, altered consciousness, or rapidly worsening symptoms appear, stop at once and seek medical care — don't delay treatment. In daily use, strictly control the dose and do not raise it on your own, to avoid discomfort.

Frequently Asked Questions About Hai Tong Pi

What is Hai Tong Pi? Are Wu Jia Pi and Sang Ji Sheng the same?

Hai Tong Pi (海桐皮) is the dried bark of Erythrina variegata or Erythrina arborescens (Erythrinae Cortex), a common Chinese herb centered on dispelling wind-damp, unblocking the channels and collaterals, and killing parasites. Wu Jia Pi dispels wind-damp and strengthens the sinews and bones, leaning to Liver and Kidney. Sang Ji Sheng dispels wind-damp and tonifies the Liver and Kidney, leaning to Liver-Kidney deficiency. The three cannot be interchanged by equal weight. Write Hai Tong Pi. Use caution in blood deficiency.

What is the composition and traditional use of Hai Tong Pi?

Pharmacopoeial name Hai Tong Pi, Latin Erythrina variegata etc. Bitter and acrid, neutral; enters the Liver and Kidney channels. It acts to dispel wind-damp, unblock the channels and collaterals, and kill parasites. It is used for wind-damp bi pain, lumbar and knee soreness, scabies and toothache. Dispels wind-damp and unblocks the channels.

How do you choose raw versus prepared? Can Wu Jia Pi replace it?

Cut into pieces and used raw. Wu Jia Pi leans to strengthening sinews without specialized parasite-killing; it cannot replace the formula by equal weight. Commercial products follow regulated processing; do not self-modify.

What is the usual dosage? Can it be drunk daily as a wind-dispelling tea?

Decocted, 6-12 g. Modern use requires a practitioner to name the dose. It is not a four-season “Erythrina tea.” Blood deficiency only injures further. Wind-damp needs a practitioner to name a short course; it does not replace assessment.

What are the contraindications? Can it be used in pregnancy?

Not suitable for blood deficiency. Use caution in non-wind-damp conditions. Pregnancy requires practitioner assessment. Stop if loose stool or fatigue appears. Red swollen severe joint pain needs immediate medical care.

Can Hai Tong Pi dispel wind-damp and unblock the channels?

It can help wind-damp bi pain with lumbar and knee soreness, scabies and toothache. It dispels wind-damp, unblocks the channels and collaterals, and kills parasites—not a specific for every bi pain or every skin disease.

Can Hai Tong Pi be drunk daily as a wind-dispelling or channel-unblocking tea?

Wind-damp may enter a short formula; blood deficiency only injures further. “Erythrina must dispel wind” does not replace assessment. Dispelling wind-damp and unblocking the channels should be named by a practitioner with form and dose.

How do you choose among Hai Tong Pi, Wu Jia Pi, Sang Ji Sheng, Du Huo and Qin Jiao?

Hai Tong Pi dispels wind-damp while unblocking the channels and killing parasites, leaning to wind-damp bi pain and scabies. Wu Jia Pi dispels wind-damp and strengthens the sinews and bones, leaning to Liver and Kidney. Sang Ji Sheng dispels wind-damp and tonifies the Liver and Kidney, leaning to Liver-Kidney deficiency. Du Huo dispels wind-damp and stops pain, leaning to the lower body. Qin Jiao dispels wind-damp and relaxes the sinews, leaning to damp-heat. Wind-damp channel-unblocking favors Hai Tong Pi; strengthening sinews favors Wu Jia Pi; tonifying Liver-Kidney favors Sang Ji Sheng; lower body favors Du Huo; damp-heat favors Qin Jiao. They may be referenced after pattern differentiation; blood deficiency forbids large Hai Tong Pi.

How is Hai Tong Pi commonly modified? What is the representative use?

Depends on the pattern. Wind-damp may add Du Huo; scabies may be used externally. Write Hai Tong Pi; do not replace the channel-unblocking action with an equal weight of Wu Jia Pi.

How do you choose and store Hai Tong Pi?

Choose regulated Chinese medicinal materials with intact bark. Moldy, damp, or abnormal-smelling lots are discarded. Store cool and dry. Buy “Hai Tong Pi”; do not replace dispelling wind-damp and unblocking the channels with an equal weight of Wu Jia Pi or Sang Ji Sheng.
