Safety Overview
1.Bakuchi — Plant Snapshot
Bakuchi, known scientifically as Psoralea corylifolia, is a pivotal herbaceous plant within the Fabaceae (Leguminosae) family, widely distributed across subtropical and warm temperate regions including India, China, and parts of Southeast Asia, as well as the Himalayan foothills and areas of Pakistan and Southern Africa. This robust annual or short-lived perennial typically grows to a height of 30 to 180 centimeters, featuring an erect, often woody stem that lignifies at its base. Its distinctive leaves are alternately arranged, ovate-rhomboid to broadly elliptic, characterized by crenate or dentate margins and a pubescent surface covered in fine, white hairs on both sides, with prominent venation. The plant adorns itself with small, delicate, bluish-purple to violet flowers, densely clustered in axillary racemes that emerge from the leaf axils, each bearing 10 to 30 blooms.
The most medicinally significant part is the fruit, often referred to as a seed in traditional contexts. These small, blackish-brown pods are flattened, kidney-shaped to ovoid, and contain a single, dark brown to black, smooth, compressed seed devoid of endosperm. These seeds are notably oily, possessing a distinct aromatic scent and a bitter, acrid taste. Taxonomically, Psoralea corylifolia is a prominent member of the genus Psoralea.
Its historical and cultural significance is profound, with its use documented in ancient Ayurvedic texts like the Charaka Samhita and Sushruta Samhita for over three millennia. The Sanskrit name 'Bakuchi' itself reflects its traditional application in skin conditions, signifying its ability to 'render clear' or 'make white' the skin, particularly in addressing depigmentation disorders. In Traditional Chinese Medicine, it is known as Bu Gu Zhi and valued for similar dermatological and tonic properties.
