Traditionally, many of these plants and herbs are used safely because the traditions dictate when and how they are to be used. It is taking them out of the traditional context and usage, that can be a problem, as I see it. Here in the West, many people do not know or understand why or how certain traditions and uses are followed, and in what proportions plants/herbs can be safely mixed with other plants/herbs to possibly balance and counteract certain adverse effects. In Ayurvedic medicine for example, that is determined on an individual basis, from what I understand. Plants/herbs are powerful drugs and used without proper guidance and knowledge, caution is advised.
