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 ginseng:four parts du zhong for synergistically stimulating collagen production (X9084879).
