Japanese Thistle Herb Classic Formulas

Primary Actions

Cools Blood and stops bleeding — hematemesis, hemoptysis, hematuria, epistaxis, uterine bleeding, and hematochezia from Blood Heat; one of the principal haemostatic herbs in TCM
Resolves toxicity and reduces swelling — carbuncles, abscesses, furuncles, and lymph node swellings from fire toxin
Disperses Blood stasis — traumatic swelling and bruising (used internally and topically)

Shi Hui San (十灰散) — classical formula for Blood-Heat bleeding; Da Ji combined with Xiao Ji (小蓟), He Ye (lotus leaf), Ce Bai Ye, Bai Mao Gen, Qian Cao Gen, Zhi Zi, Da Huang, Mu Dan Pi, and Zong Lu Pi — all ten herbs charred; principal formula for upper-body bleeding (hemoptysis, hematemesis, epistaxis) from Blood Heat
Da Ji San (大蓟散) — single-herb or two-herb decoction of Da Ji (fresh or charred) for acute uterine bleeding and hematuria; classic folk first-aid formula for Blood-Heat haemorrhage

Ben Cao Gang Mu (Li Shizhen): 'Da Ji (大蓟, great thistle) cools blood, stops bleeding, breaks blood stasis, and resolves toxic swellings — superior to Xiao Ji for reducing hard swellings; both cool blood, but Da Ji is stronger for resolving masses while Xiao Ji is preferred for urinary bleeding'
