Safety Overview
1.He Shou Wu — Botanical Snapshot
He Shou Wu, scientifically known as Reynoutria multiflora (formerly Polygonum multiflorum), is a robust perennial climbing plant belonging to the Polygonaceae family. This vigorous vine can ascend to heights of up to 3 meters (approximately 10 feet) with adequate support, twining around other vegetation or structures. Its foliage is characterized by ovate to heart-shaped leaves, typically measuring 6 to 12 cm in length, displaying a striking glossy dark green color.
During late summer to early autumn, the plant produces small, rather inconspicuous white or creamy-white flowers, which are clustered in delicate racemes, usually less than 1 cm wide. The stems are hollow, featuring a smooth, reddish-brown bark that often exhibits a subtle sheen. Native to the mountainous regions of East Asia, particularly prevalent across China in provinces like Zhejiang, Sichuan, and Yunnan, He Shou Wu thrives in moist, well-drained woodland environments and along forest margins.
The plant's most valued part is its tuberous root, which, when harvested, appears dark brown to black and can grow significantly, sometimes reaching 30 cm in length and considerable girth after several years of maturation.
