Bai Ji (白及): Bletilla Striata — TCM's Premier Hemostatic Herb for Bleeding and Wound Healing

Introduction to Bai Ji

Bai Ji (白及, Bletilla striata) is the dried tuber of a terrestrial orchid, and one of TCM’s most important hemostatic (bleeding-stopping) herbs. Its name literally means “white and reaching” — describing its white tubers that send out long reaching roots.

What makes Bai Ji extraordinary is its physical property: when mixed with water, it forms a thick, gelatinous substance that adheres to surfaces. This gives Bai Ji a unique dual action — it not only has pharmacological hemostatic effects but also physically seals and protects bleeding tissues. This combination makes it invaluable for ulcers, wounds, and internal bleeding.

Properties and Channel Entry

Property	Description
Taste	Bitter (苦), Sweet (甘), Astringent (涩)
Temperature	Slightly Cold (微寒)
Channels Entered	Lung (肺), Stomach (胃), Liver (肝)

The astringent taste is key — it “gathers and holds,” which is the TCM mechanism for stopping bleeding and containing fluids. The bitter taste clears heat, and the sweet taste supports tissue regeneration.

Key Functions

1. Stops Bleeding (收敛止血)

Bai Ji’s primary and most important function:

• Coughing blood (hemoptysis) — bleeding from the lungs
• Vomiting blood (hematemesis) — bleeding from the stomach
• Blood in stool — gastrointestinal bleeding
• Nosebleeds (epistaxis)
• Traumatic bleeding — external wounds

Unlike many hemostatic herbs that only address the pattern, Bai Ji also physically plugs the bleeding site with its gel-forming property.

2. Reduces Swelling and Generates Flesh (消肿生肌)

This is Bai Ji’s second remarkable action — it promotes tissue regeneration:

• Ulcer treatment — stomach ulcers, duodenal ulcers
• Burns — promotes skin regeneration and prevents infection
• Chronic wounds — non-healing sores, diabetic ulcers
• Cracked skin — hands, feet, nipples

3. Moistens the Lungs (润肺)

• Dry cough — the gel-like quality moistens the Lung tissue
• Cough with small amounts of blood — moistens while stopping bleeding

Clinical Applications

Gastrointestinal Bleeding and Ulcers

Bai Ji is the herb of choice for:

• Stomach ulcers (gastric ulcer)
• Duodenal ulcers
• Gastrointestinal bleeding — blood in vomit or stool
• Gastritis with erosion

Typical preparation: Bai Ji powder (3-6g) mixed with warm water, taken on an empty stomach so the gel coats the ulcer directly.

Respiratory Bleeding

• Tuberculosis with hemoptysis — historically a major application
• Bronchiectasis with blood in sputum
• Lung cancer (palliative) — managing hemoptysis
• Often combined with Bai Mao Gen (Imperata) and Ce Bai Ye (Biota leaves)

External Applications

• Wound bleeding — Bai Ji powder applied directly
• Burns — mixed with sesame oil or vaseline as a salve
• Chronic skin ulcers — promotes granulation tissue
• Cracked nipples (breastfeeding) — safe topical application
• Hemorrhoids — bleeding and tissue repair

Bai Ji in Classical Formulas

Bai Ji Zhi Xue San (白及止血散)

A modern clinical preparation:

• Bai Ji powder alone or with a small amount of San Qi (Notoginseng)
• For gastric ulcers and GI bleeding
• Taken as powder mixed with water

Bai Ji Pi Pei San (白及枇杷散)

Combines Bai Ji with Pi Pa Ye (Loquat Leaf):

• For Lung heat with coughing blood
• Clears heat while stopping bleeding and moistening

Bai Ji Hai Piao Xiao San (白及海螵蛸散)

Bai Ji + Hai Piao Xiao (Cuttlefish Bone):

• The classic combination for stomach acid and ulcers
• Bai Ji coats and regenerates; Hai Piao Xiao neutralizes acid
• One of the most effective TCM approaches to peptic ulcer disease

Modern Research

Gastrointestinal Effects

• Gastric mucosal protection — forms a protective gel layer over ulcerated tissue
• Reduces gastric acid secretion — helps ulcer healing
• Promotes ulcer healing — accelerates tissue regeneration
• Anti-Helicobacter pylori activity — relevant to ulcer treatment
• Used in Chinese hospitals for endoscopic hemostasis

Hemostatic Effects

• Promotes platelet aggregation — accelerates clot formation
• Shortens bleeding time — documented in multiple studies
• Reduces fibrinolysis — prevents premature clot breakdown

Wound Healing

• Stimulates fibroblast proliferation — key for tissue repair
• Angiogenic effects — promotes new blood vessel formation in healing tissue
• Antimicrobial properties — helps prevent wound infection
• Used in surgical procedures in China for sealing incisions

Key Active Compounds

• Bletilla glucomannan — the gel-forming polysaccharide responsible for the coating effect
• Bletilic acid — anti-inflammatory
• Various antimicrobial compounds

Preparation and Dosage

Form	Dosage	Notes
Powder (finely ground)	3–6g	Preferred form — taken with warm water for ulcers
Decoction	6–15g	Less effective than powder for coating action
Topical paste	As needed	Mixed with water, oil, or honey for external use
Capsules	As directed	Modern preparation

Critical Usage Note

For ulcer treatment, Bai Ji powder should be taken with warm water on an empty stomach so it can coat the ulcer before food interferes. The powder becomes gel-like in water, creating a physical protective layer.

Precautions

• Do not use with aconite (Wu Tou) — classical TCM contraindication
• Early-stage external disorders — the astringent nature may “trap” pathogens
• Not for bleeding from excess heat alone — combine with heat-clearing herbs
• Pregnancy — use under professional supervision
• Stomach fullness after eating — the heavy, sticky nature may worsen stagnation

Key Takeaways

• Bai Ji is TCM’s premier hemostatic herb with a unique gel-forming physical property
• Physically coats and protects ulcers while pharmacologically stopping bleeding
• Most effective for stomach ulcers when taken as powder with warm water on empty stomach
• Promotes tissue regeneration — used for burns, wounds, and chronic ulcers
• Modern research supports anti-ulcer, hemostatic, wound-healing, and antimicrobial effects
