Many herbs contain hundreds or even thousands of chemicals that have not been completely catalogued. While some may ultimately prove useful as therapeutic agents, others could well prove toxic. Most herbal products sold in different parts of the world are not standardized, which means that determining the exact amounts of their ingredients can be difficult or impossible.
