Safety Overview
1.Thunder God Vine — Essential Profile
Thunder God Vine, scientifically known as Tripterygium wilfordii, is a deciduous woody vine belonging to the Celastraceae family, native to the mountainous and forested regions of southeastern China. This perennial plant typically grows as a climbing shrub, reaching heights of several meters, often found scrambling over other vegetation in moist, well-drained loamy soils. Its leaves are ovate to elliptic, serrated along the margins, and arranged alternately along the stems.
During late spring to early summer, it produces small, greenish-white flowers clustered in terminal or axillary panicles, which later develop into distinctive three-winged (hence 'Tripterygium') reddish-brown capsules. The roots and root bark are the primary parts used in traditional medicine, particularly in Traditional Chinese Medicine (TCM), where it is known as Lei Gong Teng. For centuries, indigenous communities have valued Thunder God Vine for its potent therapeutic properties, employing it in various folk remedies to address inflammatory and autoimmune conditions.
The plant's distribution spans provinces such as Fujian, Zhejiang, Jiangxi, Hunan, Guangdong, and Guangxi, where it thrives in subtropical climates. Its complex phytochemistry underpins its powerful medicinal actions, making it a subject of extensive modern pharmacological research to validate its traditional applications while understanding its inherent toxicities.
