The fruits and seeds are used from this shrub, which grows in Russia, China, Japan and Korea. Used in traditional Chinese medicine attributing to it astringent, invigorating, detoxifying and liver protection properties, none of which have been scientifically proven (WHO 2007: p.296-313).

Precautions when taking plant preparations: 1. Ensure that they are from a reliable source: poisoning has occurred due to confusing one plant with another with toxic properties, as well as poisoning from heavy metals extracted from the ground and food poisoning due to contamination with bacteria or fungi. 2. Do not take in large amounts; follow recommendations from professional experts in phytotherapy. "Natural" products are not always good in any quantity: plants contain active substances from which much of our traditional pharmacopoeia has been obtained and can result in poisoning or act as endocrine disruptors if taken in excessive amounts or time periods.
