These include recommendations on cultivating, collecting, classification, quality control, storage, etc. Although there are no official standards governing the production of herbal medicines in the world, it is also true that the potency and purity of these products may vary widely.

Many herbal medicines interact with prescription medicines, and if the treating physician doesn't know what a patient is taking, it can be extremely detrimental.
