The 1994 Dietary Supplement Health and Education Act impacted herbal therapies in what way?

ANS: B
The Dietary Supplement Health and Education Act of 1994 allowed companies to sell herbs as dietary supplements as long as no health claims are written on their labels. Herbal medicines do not undergo the same rigorous research as pharmaceuticals, so most have not received approval for use as drugs and are not regulated. Therefore, they cannot be labeled as safe. Herbs do not come with classification systems. Herbal supplements come in a variety of packages, elixirs, pills, salves, and tinctures, and being labeled a dietary supplement does not necessarily imply that the supplement is a food product.
