Dosages (Du Zhong) :
 6 - 15 g bark, in decoction, pill, powder, or tincture (FAY); 30 drops 10% tincture 3 ×/day, ca 9 months, for high blood pressure (FAY).

Contraindications, Indications, and Side Effects (Du Zhong) :
Class 1 (AHP). Not covered (KOM; PH2).

Extracts (Du Zhong) :
Quercetin (at 8.5 µM) was most potent of 5-alpha-glucosidase inhibitors found in extracts of the leaves (X9028049). Leaves contain several anticlastogenic (antimutagenic) compounds (asperulosidic acid, deacetyl asperulosidic acid, asperuloside, geniposidic acid, geniposide, p-trans-coumaric acid pyrogallol, and protocatechuic acid) (X9025787). At 100 µg/ml, the leaf extract was more potent a radical scavenger than isolated protocatechuic acid at the same concentration, clearly a super example of synergy (X10956129). With at least six compounds that tend to stimulate collagen production, this herb certainly has antiaging potential (including antiwrinkle activity). Scientists favor one part inseng: four parts du zhong for synergistically stimulating collagen production (X9084879).
