My beef with herbal concoctions is not that they cannot work (like homeopathy or therapeutic touch) but that they are not properly regulated. Herbs contain chemicals that can have a pharmacological action in the body, can alter metabolism, have toxicity, and can interact with other drugs. In other words – they are drugs. They are simply not purified and quantified, and most countries do not require testing for herbs similar to pharmaceuticals. So they are unreliable drugs.

The most common example of this are diet supplements, which commonly contain stimulants. I recently surveyed all the diet supplement products at my local grocery store and almost all of them had some form of caffeine as a major ingredient. It used to be common for such products to contain ephedra (another stimulant) – until it was banned by the FDA for causing cardiac deaths.
