This is the latest in a series of studies on the embryotoxicity of one of the main ginseng extracts. It is important to note that even though the agent is an isolate of ginseng, other epidemiological data has also shown higher incidences of problems in humans using ginseng. Now, we have no controls for pesticides, etc., so it may not be the ginseng but just to be safe, we advise all pregnant patients to avoid ginseng.
