When we think about dietary supplements, which are a subset of natural health products, I think a confusing thing for many people is the idea that because they're natural supplements, they're somehow benign, but that is not at all the case. Dietary supplements include products like iron tablets, which, as well as being a crucial health product for many people suffering from amenia, is also a leading cause of poisoning of young children when they inadvertently swallow the tablets. Glucosamine is an important treatment for osteoarthritis, and borne out of many clinical studies; and St John's Wort as well is a product that has many interactions with important medicines that people take. So these products can be helpful to people, and they are certainly not at all benign from a safety perspective.
