Bai Ji (Bletilla striata) contains mucilaginous compounds called glycomannans and the hemostatic agent bletillin, which work together to promote blood clotting. When applied internally or externally, these compounds form a protective film over wounds and ulcers, accelerating platelet aggregation and wound contraction. The sticky polysaccharide content creates a physical barrier that helps seal bleeding vessels while simultaneously reducing inflammation at the site of injury. Evidence level: C (preclinical and traditional use data).
Does Bai Ji interact with blood thinners or other medications?
Bai Ji has hemostatic properties that may theoretically antagonize the effects of anticoagulant and antiplatelet medications such as warfarin, heparin, aspirin, and clopidogrel. Due to its ability to accelerate blood clotting, concurrent use could reduce the efficacy of blood-thinning medications. Additionally, the mucilaginous content may affect absorption of orally administered drugs. Patients taking anticoagulants should consult a healthcare provider before using Bai Ji. Evidence level: C/Theoretical.
What is the recommended dosage for Bai Ji?
The standard adult dosage of Bai Ji is 3-9 grams daily when taken internally as a decoction or powder. For hemostatic purposes, it is typically administered in divided doses. The herb can also be applied topically as a powder for wound healing and skin conditions. Dosage should be individualized based on the specific condition being treated and under guidance from a qualified practitioner. Evidence level: C/Traditional use.
Is Bai Ji safe to take during pregnancy?
Bai Ji is contraindicated during pregnancy and should be avoided. Traditional Chinese medicine principles consider it inappropriate for pregnant women, as its strong hemostatic and astringent properties may interfere with normal blood circulation required during pregnancy. There is insufficient safety data regarding use during breastfeeding. Women who are pregnant, planning pregnancy, or breastfeeding should not use Bai Ji without explicit guidance from a qualified healthcare provider. Evidence level: Traditional/Contraindicated.
What is Bai Ji used for in traditional Chinese medicine?
Bai Ji is primarily used in traditional Chinese medicine to stop bleeding, heal ulcers, and reduce swelling, particularly in the lungs and digestive tract. Common indications include hemoptysis (coughing up blood), peptic ulcers, gastric bleeding, and traumatic wounds. Its mucilaginous properties make it effective for protecting and healing damaged mucous membranes. Externally, it is applied for burns, sores, and cracked skin. Evidence level: C (limited clinical data, primarily traditional use).

Résumé
Bletilla striata (Bai Ji) is a traditional Chinese medicinal herb known for its hemostatic, anti-inflammatory, and wound-healing properties [PMID:27865796, PMID:37898246].
Contexte
Bletilla striata (Thunb.) Reichb. f., also known as Hyacinth Orchid or Baiji, is a perennial plant from the Orchidaceae family [PMID:27865796, PMID:28276764].
Usages traditionnels
Traditionally used for the treatment of hematemesis, hemoptysis, traumatic bleeding, tuberculosis, pneumonophthisis, pneumonorrhagia, and hemorrhage of the stomach or lung [PMID:27865796, PMID:28276764]. It is also applied topically for ulcers, sores, swellings, chapped skin, hemorrhoids, anthrax, and eye diseases [PMID:27865796].
Composés actifs
The herb contains Bletilla striata polysaccharides (BSP), a linear β-(1→4)-glucomannan composed of mannose and glucose [PMID:41116515, PMID:42197196]. Other identified compounds include approximately 158 to 294 constituents, such as glucosides, bibenzyls, phenanthrenes, quinones, biphenanthrenes, dihydrophenanthrenes, anthocyanins, steroids, triterpenoids, phenolic acids, neolignan glycosides, and stilbenoids [PMID:31736742, PMID:40645542, PMID:37757922, PMID:30585518].
Mécanisme d'action
BSP alleviates ARDS by inhibiting NETs-induced pyroptosis in pulmonary alveolar macrophages via the PAD4 pathway [PMID:39954881]. In skin damage, it activates the Nrf2/HO-1 signaling pathway and suppresses ferroptosis by upregulating GPX4 and FTH1 [PMID:41116515]. It also inhibits the TNF-α/NF-κB pathway and upregulates IL-10 for anti-inflammatory effects [PMID:40368564]. In liver disease, it modulates the NLRP3/caspase-1/GSDMD signaling pathway [PMID:40626309] and enhances hepatocyte RelA/HNF1α signaling [PMID:39877717]. Gymconopin C regulates the miR-6777-5p/ADRB2 pathway to promote mitophagy in lung cancer cells [PMID:41423048].
