Introduction
Damnacanthus indicus is an evergreen shrub native to eastern Asia, traditionally used in folk medicine for rheumatism, pain relief, improved blood circulation, and inflammatory conditions. Modern research has identified diverse bioactive compounds in this plant, including 112 anthraquinones and 66 non-anthraquinones, as well as flavones such as quercetin and kaempferol, which contribute to its antioxidant and anti-inflammatory properties. Damnacanthus Indicus Extract 2% Total Flavones Powder is a standardized herbal flavone powder produced through advanced extraction processes, delivering consistent flavone content for pharmaceutical, nutraceutical, cosmetic, and functional food applications. Huilin supplies this natural extract with 2% Indian herb root under strict quality control, supported by full documentation including COA and batch traceability.
