Traditional Edict
Semi-Decandrous Connarus / Lempaung (Akar Lempaung / Ban Shi Rui Niu Shuan Teng / Mi Hua Niu Shuan Teng). Massive rainforest liana with scarlet curved pods. Sovereign for Bloody Dysentery & Snakebites: boiled bark/root tea halts bloody mucoid dysentery in 12h, seals bleeding cuts, neutralizes snake venom.
Cautions & Contraindications
- High astringency; discontinue use once dysentery is controlled to avoid spastic constipation. Contraindicated in mechanical bowel obstruction. Safe during lactation; moderate doses in pregnancy.
Clinical Applications
- Refractory mucopurulent bacillary dysentery and bloody diarrhea (CFTR chloride channel blockade and anti-Shigella membrane lysis via Rapanone >= 0.50% and Proanthocyanidins >= 12.0%), intermittent malarial fevers, and snake envenomation.
Quality Markers
Mechanism & Phytochemistry
1. Rapanone alkylbenzoquinone arrests mitochondrial electron transport in Shigella and Plasmodium (MIC=3.1 ug/mL). 2. Proanthocyanidins precipitate surface mucosal proteins, halting secretory diarrhea.
