Also known as: Ròu Hóng (肉红), Nèi Xiāo (内消), Zǐ Jīng Mù Pí (紫荆木皮),

Chinese redbud bark is a Blood-moving herb used in traditional Chinese medicine primarily for menstrual problems caused by Blood stasis, joint pain from Wind-Dampness, and swollen skin infections or abscesses. It has a bitter taste and neutral temperature, making it gentle enough to both move stagnant Blood and help clear toxic swellings. It is also used for painful urination and can be applied externally as a poultice for boils and insect bites.

What This Herb Does

Every herb has a specific set of actions — here's what Zi Jing Pi does in the body, explained in both everyday and TCM terms

Therapeutic focus

In practical terms, Zi Jing Pi is primarily used to support these areas of health:

Women's Health Joint and Muscle Pain Relief Skin Health Urinary Health

TCM Actions

In TCM terminology, these are the specific therapeutic actions that Zi Jing Pi performs to restore balance in the body:

Invigorates Blood and Regulates Menstruation Resolves Toxicity and Reduces Swelling Promotes Urination and Relieves Stranguria Dispels Wind-Dampness and Alleviates Pain Invigorates Blood and Dispels Stasis

How these actions work

'Activates Blood and promotes menstruation' means Zi Jing Pi helps move stagnant Blood, restoring healthy circulation. This is particularly relevant for menstrual disorders where Blood has become stuck, causing missed periods, painful periods, or abdominal pain from old, congealed Blood. The Kai Bao Ben Cao (an early Song dynasty herbal text) records its primary action as 'breaking accumulated old Blood.'

'Resolves swelling and reduces toxicity' refers to the herb's ability to reduce swollen, inflamed tissue caused by toxic accumulation. It is a key herb for abscesses, boils, and deep tissue infections (known in classical surgery texts as 'flowing abscesses'). It can be applied both internally and externally for these conditions. Li Shizhen noted that its bitter taste and neutral-to-cool nature allow it to both move Blood and clear toxins at the same time.

'Promotes urination and relieves strangury' means the herb helps ease painful or difficult urination. This was one of its earliest recorded uses, and it applies to conditions where Blood stasis obstructs the urinary passages, causing burning, pain, or dribbling.

'Dispels Wind-Dampness and alleviates pain' describes its use for joint and muscle pain caused by Wind, Cold, and Dampness invading the channels. It enters the Liver channel (which governs sinews) and the Spleen channel (which manages Dampness), making it suitable for painful obstruction conditions affecting the limbs and joints.

Patterns Addressed

In TCM, symptoms cluster into recognizable patterns of disharmony. Zi Jing Pi is used to help correct these specific patterns.

Why Zi Jing Pi addresses this pattern

Zi Jing Pi directly addresses Blood Stagnation by actively moving and dispersing accumulated old Blood. Its bitter taste has a descending and dispersing quality that breaks through congealed Blood, while its Liver channel entry targets the organ responsible for the smooth flow of Blood. Classical sources describe it as able to 'break old stagnant Blood' (破宿血), making it well suited for patterns where Blood has stopped moving freely, causing pain, masses, or menstrual irregularities.

A practitioner would look for one or more of these signs

Painful Periods

Fixed, stabbing menstrual pain due to Blood stasis

Irregular Menstruation

Missed or delayed periods with dark clotted blood

Abdominal Pain

Lower abdominal pain that worsens with pressure

Commonly Used For

These are conditions where Zi Jing Pi is frequently used — but only when they arise from the specific patterns it addresses, not in all cases

Arises from: Blood Stagnation

TCM Interpretation

In TCM, painful periods are most commonly understood as a failure of Blood to flow freely through the uterus during menstruation. When Blood becomes stagnant (stuck), it creates a blockage that produces sharp, fixed pain, often with dark clots. The Liver is the primary organ involved, since it stores Blood and ensures its smooth movement. When the Liver's flow-regulating function is impaired, Blood can congeal in the lower abdomen and uterus.

Why Zi Jing Pi Helps

Zi Jing Pi directly enters the Liver channel and is classically described as able to 'break old stagnant Blood.' Its bitter taste has a dispersing quality that pushes through congealed Blood, while its neutral temperature means it does not add excess Heat or Cold to the body. For menstrual pain with Blood stasis, it was traditionally powdered and formed into pills with vinegar paste, then dissolved in wine to enhance its Blood-moving effect.

Also commonly used for

Dosage & Preparation

These are general dosage guidelines for Zi Jing Pi — always follow your practitioner's recommendation, as dosages vary based on the formula and your individual condition

Standard dosage

6-15g

Maximum dosage

Up to 30g in severe impediment (Bi) syndromes or external poultice preparations, under practitioner supervision. Classical wine-decoction recipes such as those in the Dian Nan Ben Cao used up to 60g (二两) but this was in medicinal wine preparations with extended soaking, not standard decoction.

Dosage notes

Standard dosage is 6 to 15g in decoction for internal use. For Blood stasis conditions such as amenorrhoea or painful menstruation, the middle range (9 to 12g) is typical. For Wind-Damp impediment pain, doses toward the higher end (12 to 15g) may be used. Classical sources frequently combine Zi Jing Pi with wine (either wine-decoction or medicinal wine soaking) to enhance its Blood-moving and channel-entering properties. For external use in poultices for abscesses and swellings, larger quantities of powder are mixed into pastes with no fixed upper limit, as it is applied topically. The Dian Nan Ben Cao recommends stir-frying the bark with rice wine (酒炒) before use.

Preparation

No special decoction handling is required. Zi Jing Pi is decocted normally with other herbs. Classical sources recommend stir-frying the bark with rice wine (酒炒, jiu chao) to enhance its Blood-invigorating effect and direct it into the channels. It may also be ground into powder for pills, soaked in medicinal wine, or ground into fine powder and mixed into paste for external application on swellings and abscesses.

Processing Methods

In TCM, the same herb can be prepared in different ways to change its effects — here's how processing alters what Zi Jing Pi does

Processing method

The bark is stir-fried with rice wine (yellow wine) until fragrant and slightly dry.

How it changes properties

Wine-frying enhances Zi Jing Pi's Blood-moving and channel-opening properties. The warming nature of wine helps guide the herb into the channels and joints, strengthening its ability to dispel Wind-Dampness and invigorate Blood circulation. The temperature shifts slightly warmer.

When to use this form

Preferred for Wind-Damp joint pain (painful obstruction syndrome), especially when combined with other herbs in wine-based decoctions. The Dian Nan Ben Cao specifically calls for the wine-fried form when treating joint and bone pain with Wind-Cold-Damp obstruction.

Common Herb Pairs

These ingredients are traditionally combined with Zi Jing Pi for enhanced therapeutic effect

Bai Zhi
Bai Zhi 1:1

Together, Zi Jing Pi and Bai Zhi form the classical external formula Yi Sheng Gao from the Xian Chuan Wai Ke Ji Yan Fang. Zi Jing Pi activates Blood and resolves toxicity while Bai Zhi disperses Wind, reduces swelling, and draws out pus. The pair is especially effective for the early stages of abscesses and boils, when the swelling is just forming and can still be resolved internally.

When to use: Early-stage skin abscesses or boils before they have fully ripened, applied topically mixed with wine.

Du Huo
Du Huo 5:3 (Zi Jing Pi 5 liang : Du Huo 3 liang, as in Chong He Xian Gao)

Zi Jing Pi activates Blood and resolves toxic swelling while Du Huo dispels Wind-Dampness from the lower body and joints. Together they address both the Blood stasis and the Wind-Damp obstruction that combine to create deep tissue swellings and painful joints. This pairing forms the core of the famous Chong He Xian Gao formula.

When to use: Deep abscesses, flowing abscesses (liu zhu), or stubborn joint pain with signs of both Blood stasis and Wind-Damp obstruction.

Dang Gui
Dang Gui 2:1 (Zi Jing Pi : Dang Gui)

Dang Gui nourishes and moves Blood while Zi Jing Pi focuses on breaking through stagnant old Blood. Together, they provide both the force to disperse Blood stasis and the nourishment to generate new healthy Blood, preventing the strong stasis-breaking action from leaving the body depleted.

When to use: Menstrual disorders from Blood stasis, especially when accompanied by Blood deficiency; also for joint pain formulas where Blood needs both nourishing and moving.

Chi Shao
Chi Shao 5:2 (Zi Jing Pi : Chi Shao, as in Chong He Xian Gao)

Both herbs enter the Blood level: Chi Shao (Red Peony root) cools Blood and clears Blood-level Heat, while Zi Jing Pi breaks through old stagnant Blood. Together they address conditions where Blood stasis and Heat toxins coexist, such as hot, swollen abscesses with underlying stagnation.

When to use: Abscesses and boils with redness, heat, and swelling indicating both Blood stasis and Heat toxins. Both herbs appear together in the Chong He Xian Gao formula.

Key Formulas

These well-known formulas feature Zi Jing Pi in a prominent role

Chong He Gao 冲和膏 King

This is the defining formula for Zi Jing Pi, from Yang Qingsou's Xian Chuan Wai Ke Ji Yan Fang. Li Shizhen specifically highlighted this formula when discussing Zi Jing Pi's properties. As the King herb at 5 liang (the largest dose in the formula), it showcases the herb's core ability to activate Blood, resolve swelling, and clear toxins from abscesses and deep tissue infections. The formula treats all types of abscesses, flowing abscesses, and boils of uncertain thermal nature.

Comparable Ingredients

These ingredients have overlapping uses — here's how to tell them apart

Tao Ren
Zi Jing Pi vs Tao Ren

Both activate Blood and dispel stasis, but Tao Ren (Peach kernel) is stronger at breaking stasis in the lower abdomen and has an additional moistening quality that helps lubricate the intestines. Zi Jing Pi has a broader scope that includes resolving toxic swelling and treating skin abscesses, which Tao Ren does not address. For pure menstrual Blood stasis, Tao Ren is more commonly used; for abscesses and external swellings with stasis, Zi Jing Pi is preferred.

Ru Xiang
Zi Jing Pi vs Ru Xiang

Both herbs move Blood and reduce swelling, and both are used for traumatic injuries and abscesses. However, Ru Xiang (Frankincense) is acrid and warm, primarily working through its aromatic, penetrating quality to move Qi and Blood in the sinews and channels, making it stronger for traumatic pain. Zi Jing Pi is bitter and neutral, better suited for toxic abscesses and conditions where stasis and Heat coexist, and it also addresses urinary symptoms that Ru Xiang does not.

Yi Mu Cao
Zi Jing Pi vs Yi Mu Cao

Both herbs activate Blood and are used for menstrual disorders. Yi Mu Cao (Motherwort) is slightly cold and has additional diuretic and Heat-clearing properties, making it more appropriate when Blood stasis is accompanied by Heat or edema. Zi Jing Pi is neutral and has a stronger affinity for resolving external toxic swellings. For purely gynecological Blood stasis, Yi Mu Cao is more commonly prescribed; Zi Jing Pi is chosen when the presentation also involves abscesses, joint pain, or skin conditions.

Common Substitutes & Adulterants

Related species and common adulterations to be aware of when sourcing Zi Jing Pi

The most important source of confusion is between Zi Jing Pi (紫荆皮, bark of Cercis chinensis, Fabaceae) and Zi Jin Pi (紫金皮, root bark of Kadsura longipedunculata, Magnoliaceae). Because their names sound nearly identical in Chinese, they have been mixed up in trade for centuries. To distinguish them: authentic Zi Jing Pi (Cercis) is tree bark, greyish-brown on the outside and purplish-brown inside, with no aroma, a bitter-astringent taste, and visible sparkling points in cross-section. Zi Jin Pi (Kadsura) is root bark from a vine, purple-coloured and fragrant with a distinctive menthol-like cooling spiciness (described classically as "like camphor entering the brain"). Additionally, bark from Lagerstroemia indica (紫薇, crape myrtle, Lythraceae) is used as Zi Jing Pi in some regional standards (e.g. Chongqing). This bark is lighter, more easily broken, and lacks the sparkling points of authentic Cercis bark. Bark from Cercis yunnanensis (Yunnan redbud) is also used locally as a substitute in Yunnan, appearing orange-red or orange-yellow externally with horizontal striations.

Toxicity Classification

Classical Chinese pharmacopoeia toxicity rating for Zi Jing Pi

Non-toxic

Zi Jing Pi is classified as non-toxic (无毒) in classical sources from the Kai Bao Ben Cao onward, and this has been consistent through historical records. Animal toxicity studies have found that the LD50 of the bark decoction administered orally in mice is approximately 100.5 g/kg, indicating a very wide safety margin at standard therapeutic doses. The bark contains tannins and small amounts of volatile oils, with no known highly toxic alkaloids or other dangerous compounds. At standard doses of 6 to 15 grams, no significant adverse effects have been documented. Some modern references note a cautious classification with one source suggesting a possible mild toxicity, likely based on the tannin content, but this is not the mainstream view.

Contraindications

Situations where Zi Jing Pi should not be used or requires extra caution

Avoid

Pregnancy: Zi Jing Pi actively moves Blood and breaks stasis, which can stimulate the uterus and potentially cause miscarriage. Classical sources explicitly state that pregnant women must not take this herb.

Caution

Spleen and Stomach deficiency with weakness: the bitter, Blood-moving nature of this herb may further tax a weak digestive system. Use with caution or combine with Spleen-supporting herbs.

Caution

Excessive menstrual bleeding or active hemorrhage without clear Blood stasis: the Blood-invigorating action may worsen bleeding if stasis is not the underlying cause.

Special Populations

Important considerations for pregnancy, breastfeeding, and pediatric use

Pregnancy

Contraindicated during pregnancy. Zi Jing Pi is a Blood-invigorating herb whose primary actions include breaking old stagnant Blood and promoting Blood circulation. These properties carry a risk of stimulating uterine contractions and promoting menstrual flow, which could lead to miscarriage or premature labour. Multiple classical and modern Chinese Materia Medica sources explicitly state: "Pregnant women must not take this herb" (孕妇忌服 / 孕妇禁服).

Breastfeeding

No specific classical or modern data exists on the safety of Zi Jing Pi during breastfeeding. Given its Blood-invigorating and stasis-breaking properties, caution is advised. There is no documented evidence of transfer through breast milk, but due to the general lack of safety data, it is best avoided during breastfeeding unless specifically prescribed by a qualified practitioner who has determined the benefits outweigh potential risks.

Children

No specific classical or modern guidelines exist for paediatric use of Zi Jing Pi. Some sources note that children should avoid this herb due to its Blood-invigorating properties. If used in older children under the guidance of a qualified practitioner, dosage should be reduced proportionally based on age and body weight, typically to one-third to one-half of the adult dose.

Drug Interactions

If you are taking pharmaceutical medications, be aware of these potential interactions with Zi Jing Pi

No well-documented pharmacological drug interactions have been established for Zi Jing Pi in peer-reviewed literature. However, based on its traditional Blood-invigorating and stasis-breaking actions, theoretical caution is warranted with:

  • Anticoagulant and antiplatelet medications (e.g. warfarin, heparin, aspirin, clopidogrel): The Blood-moving properties of Zi Jing Pi could theoretically potentiate anticoagulant effects and increase bleeding risk.
  • Non-steroidal anti-inflammatory drugs (NSAIDs): Combined use may have additive effects on inflammation pathways and bleeding risk.

These interactions are theoretical based on the herb's known pharmacological profile (anti-inflammatory, analgesic, Blood-moving). No clinical case reports of adverse interactions have been published. Patients taking blood-thinning medications should inform their healthcare provider before using this herb.

Dietary Advice

Foods and dietary considerations when taking Zi Jing Pi

When taking Zi Jing Pi for Blood stasis or pain conditions, avoid excessively cold and raw foods, as these can constrict Blood flow and counteract the herb's warming, Blood-moving action. Classical formulas frequently pair Zi Jing Pi with wine or use wine as a decoction medium, reflecting the traditional understanding that moderate alcohol enhances Blood circulation and the herb's therapeutic effect. No specific food incompatibilities have been recorded.

Botanical Description

Physical characteristics and morphology of the Zi Jing Pi source plant

Cercis chinensis Bunge (Chinese redbud) is a deciduous shrub or small tree in the Fabaceae (legume) family, typically growing 2 to 5 metres tall, occasionally reaching up to 8 metres. The bark is greyish-white to brownish-black, becoming scaly with age and revealing orange inner bark underneath. The leaves are alternate, simple, and distinctly heart-shaped (cordate), 6 to 14 cm long, with a glossy green surface and smooth margins, turning yellow-green in autumn.

One of its most striking features is cauliflory: clusters of tiny, rose-purple, pea-shaped flowers bloom profusely directly on older branches and even the main trunk in early spring (March to April) before the leaves emerge, creating a spectacular display. After flowering, flat, bean-like seed pods 5 to 7.5 cm long develop, ripening from green to dark brown by October. The plant is native to central and southern China, growing naturally in woodlands, thickets, and hillside slopes, and is widely cultivated as an ornamental in gardens and courtyards.

Sourcing & Harvesting

Where Zi Jing Pi is sourced, when it's harvested or collected, and how to assess quality

Harvesting season

July to August; tree bark is stripped, brushed free of soil and debris, and sun-dried.

Primary growing regions

Zi Jing Pi is distributed throughout much of China, including North China (Hebei, Shandong), East China, Central-South China, Southwest China, as well as Shaanxi and Gansu provinces. The best quality (dao di) material historically comes from Sichuan (川中), as noted by Li Shizhen in the Ben Cao Gang Mu. Major producing regions today include Sichuan, Henan, Hunan, Hubei, and Jiangxi provinces. The plant grows wild on mountain slopes, stream banks, and in thickets, and is also widely cultivated in gardens and courtyards.

Quality indicators

Good quality Zi Jing Pi bark is long, thick (3 to 6 mm), and firm. The outer surface should be greyish-brown with wrinkles and a scaly appearance. The inner surface should be a distinctive purplish-brown or reddish-brown colour with fine longitudinal striations. The cross-section should be greyish-red. A key identifying feature is that when held up to light, fine sparkling points (small bright spots) are visible in the cross-section. The bark should be hard and difficult to break, with a fibrous fracture. It has virtually no odour, and the taste should be bitter and astringent with a slight cooling sensation. As Li Shizhen noted, the best quality bark is thick, purple in colour, and "bitter as bile" (苦如胆). Avoid bark that is thin, pale, or easily crumbled.

Classical Texts

Key passages from the classical Chinese medical texts that describe Zi Jing Pi and its therapeutic uses

《开宝本草》(Kai Bao Ben Cao, Song Dynasty)

Original: 主破宿血，下五淋，浓煮服之。

Translation: It principally breaks old, stagnant Blood and treats the five types of painful urinary dribbling (lin syndrome). It should be decocted thickly and taken as a drink.

《本草纲目》(Ben Cao Gang Mu, Li Shizhen, Ming Dynasty)

Original: 活血行气，消肿解毒，治妇人血气疼痛，经水凝涩。

Translation: It invigorates Blood, moves Qi, reduces swelling, and resolves toxins. It treats women's Blood-Qi pain and congealed, obstructed menstruation.

《本草纲目》(Ben Cao Gang Mu) — on quality

Original: 紫荆，其皮入药，以川中厚而紫色味苦如胆者为胜。

Translation: For Zi Jing Pi used in medicine, bark from Sichuan that is thick, purple in colour, and bitter as bile is considered the best quality.

《滇南本草》(Dian Nan Ben Cao, Ming Dynasty)

Original: 治筋骨疼痛，风寒湿痹，麻木不仁，瘫痪痿软，暖筋，止腰痛，治妇人血寒腹痛。

Translation: It treats sinew and bone pain, Wind-Cold-Damp impediment, numbness and loss of sensation, paralysis and weakness, warms the sinews, stops lower back pain, and treats women's abdominal pain from Blood Cold.

《本草述》(Ben Cao Shu, Qing Dynasty)

Original: 兹味能活血而解毒，则必非苦寒，亦非苦温，本草所谓气平者是也……此味活血解毒，功能并奏，则血瘀而有热者，岂非适宜之善物乎。

Translation: This substance can both invigorate Blood and resolve toxins. It is neither bitter-cold nor bitter-warm, but rather what the Materia Medica calls "neutral in Qi"... Since it simultaneously invigorates Blood and resolves toxins, for conditions where Blood stasis is accompanied by Heat, is it not an ideal medicine?

Historical Context

The history and evolution of Zi Jing Pi's use in Chinese medicine over the centuries

Zi Jing Pi has a complex textual history marked by significant name confusion. The name "Zi Jing" (紫荆, "purple thorn") first appeared in Tang dynasty texts, but the plant described was likely not the same species used medicinally today. It was not until the Song dynasty work Kai Bao Ben Cao (开宝本草, 973 CE) that Zi Jing Mu (紫荆木) was clearly identified and its Blood-breaking and urinary-draining properties recorded. This was the earliest reliable record of the medicinal use of the bark from Cercis chinensis.

A persistent source of confusion has been the conflation of Zi Jing Pi (紫荆皮, from the leguminous tree Cercis chinensis) with Zi Jin Pi (紫金皮, from the Magnoliaceae vine Kadsura longipedunculata). Because the Chinese characters 荆 (jing) and 金 (jin) sound similar, the two herbs were frequently mixed up in prescriptions from the Song dynasty onwards. Scholarly efforts to distinguish them intensified during the Yuan and Ming periods, and modern pharmacopoeia work continues to clarify this distinction. The name Zi Jing itself is thought to derive from the idea of "the essence of wood" (木之精), and the plant's striking purple-red flowers inspired the famous story of the "Tian brothers' tree" from the Southern Dynasties period, which became a classical symbol of family unity. Li Shizhen's Ben Cao Gang Mu provided detailed botanical descriptions and noted that Sichuan-produced bark, thick and bitter as bile, was the finest quality, consolidating the herb's place in external medicine (surgery) particularly through its use as the chief herb in the celebrated Chong He Xian Gao (冲和仙膏) formula.

Modern Research
