Bu Gu Zhi Tincture & Alcohol-Free Extract

Bu Gu Zhi (Psoralea corylifolia, now classified as Cullen corylifolium), the babchi of India, is an erect annual of the pea family, Fabaceae, native to India, Sri Lanka, Myanmar, and southern China and grown as a crop in Henan and Sichuan. It grows 60 to 120 centimeters with grooved stems and broadly oval, coarsely toothed leaves, both dotted with conspicuous black glands. Dense, rounded heads of small bluish-purple pea flowers appear in the leaf axils in late summer. Each produces a single flattened, bean-shaped, black pod 4 to 5 millimeters long, fused to its seed, with a strong aromatic smell and a bitter, pungent taste. We extract the dried fruit.
