Traditional Edict
Chinese Ground Orchid (Bai Ji / Anggerik Bumi / Lian Ji Cao). Translucent claw-shaped corms with magenta flowers. Undisputed Emperor of Hemostasis & Ulcer Sealing: fine powder swallowed directly forms an instant bio-gel shield over bleeding stomach ulcers, stops vomiting blood, seals chapped skin.
Cautions & Contraindications

Clinical Applications
- Acute upper gastrointestinal peptic ulcer bleeding (rapid bio-adhesive hydrogel eschar formation via BSP >= 45.0% and Militarine), pulmonary tuberculosis hemoptysis, and diabetic foot ulcers/burn wounds.
Quality Markers
Mechanism & Phytochemistry
1. BSP glucomannan polymers cross-link with tissue mucins, forming an acid-resistant mechanical hydrogel barrier over ulcer craters. 2. Militarine stimulates VEGF and ERK1/2 for rapid tissue granulation.
Preparation & Dosage
CRITICAL ULTRA-FINE POWDERING MANDATE (Bai Ji Fen): 3.0 to 6.0 g pure micro-powder (120-200 mesh) swallowed directly (Chong Fu) with warm rice soup 30 min before meals (creates bio-gel ulcer seal). Bleeding wounds: dust powder directly. Decoction: 6-15 g.
Appended Prescriptions
