A plant native to China. There is also a patented medicine called Jin Bu Huan which contains this plant (Horowitz 1996). It is used in traditional Chinese medicine which attributes to it analgesic, sedative and other properties, none of which have been clearly scientifically proven (Fu 2011). There is little published literature. Since the last update we have not published data on its excretion in breast milk. It has caused cases of acute hepatitis and extreme fatigue in adults (Teschke 2012-2014, Conti 2008, Divinsky 2002, McRae 2002, Stickel 2000, Picciotto 1998, Horowitz 1996, Kaptchuk 1995, CDC 1994, Woolf 1994, CDC 1993), drowsiness, muscle weakness, respiratory depression and bradycardia in children (Horowitz 1996, CDC 1993) and has been withdrawn from sale in several countries (Health Canada 2008). 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.
