It's a multi-million dollar industry and it's growing fast. Herbal remedies have become very popular as consumers are increasingly demanding natural products. But consumers may not always be getting what they bargained for. Many natural products contain toxins and other harmful ingredients and because herbal remedies are considered food and not drugs, manufacturers do not usually list maximum doses and possible side-effects. Also, because they are unregulated, there have been cases where the herb listed on the bottle was not even the one in the container.
