Can Polygonum multiflorum (He Shou Wu) be consumed by steeping directly in water?

Generally speaking, Polygonum multiflorum (He Shou Wu) should not be consumed by steeping directly in water. The specific analysis is as follows:

Polygonum multiflorum contains components such as anthraquinones and stilbene glycosides, most of which are lipid-soluble. When steeped directly in water, these components are difficult to fully dissolve in water, resulting in the ineffective release of its medicinal properties and making it hard to achieve the expected health benefits or therapeutic effects. Moreover, raw Polygonum multiflorum has certain hepatotoxicity and nephrotoxicity. Drinking water steeped with raw Polygonum multiflorum directly may cause damage to the liver and kidneys.

It is recommended to purchase properly processed Polygonum multiflorum from reputable pharmacies, and avoid using wild or unprocessed varieties. Each usage should not involve excessive amounts, as overuse may increase health risks. During consumption, individuals should closely monitor their physical condition. If symptoms such as nausea, vomiting, diarrhea or other discomforts occur, consumption should be stopped immediately and medical attention sought promptly.

In daily life, it is recommended to use any herbal ingredients under the guidance of a physician. At the same time, maintaining good living habits and a light diet can help maintain overall health.
