Ohwia caudata · Accepted scientific name
Scientific literature: Very Sparse (3 studies) · ★☆☆☆☆
Ohwia caudata is a versatile medicinal plant whose therapeutic potential is derived from its leaves, roots, and stems. Research indicates that various preparations, such as leaf hydroethanolic extracts, possess significant antioxidant, hypoglycemic, and hypolipidemic activities. These biological effects are largely driven by key chemical constituents, including flavonoids, eupatilin, 8-prenylquercetin, and 3',4'-dimethoxyflavone. Specifically, the plant plays a role in managing hypoglycemic conditions by influencing factors such as IL-6, pancrelipase, and Sirt1. Consequently, studying these extracts provides vital insights into the plant's complex biochemical impact on metabolic health.
