Polygonatum Officinale Rhizome/Root Extract

Overview

Polygonatum officinale rhizome/root extract is an extract obtained from the rhizomes of Solomon’s seal, Polygonatum odoratum.

The extraction focuses on the polysaccharides and saponins from the root, and, allegedly, on its lily-like scent. This could make it a fragrant and (possibly) slightly humectant ingredient, although, unfortunately, there is not much information in the scientific literature about this ingredient and its effects on the skin.

This plant, closely related to Lily of the valley, contains toxic cardiac glycosides. The rhizome extract used for skincare purposes, however, should not contain any.

Polygonatum officinale has a long tradition of use in Chinese traditional medicine as a cardiovascular tonic and diuretic.
