Herbs are selected according to their dominant properties for healing. Herbal treatment for your condition will take into account the weaknesses that present themselves, and may include treatment for organs and systems that do not seem to be directly involved with your symptoms. This is because in herbal medicine we treat the whole person.
There is no need to isolate out the active ingredients from these powerful and magnificent plants. When you split apart a whole plant, you fractionate its wholeness, and produce compounds that are concentrated, and just as capable of causing harm as good in your body.
