What’s in a name? The Complexity of Medicinal Plant Products
Joseph M. Betz, Ph.D., NIH Office of Dietary Supplements
Medicinal plant research ranges from discovery of new drug molecules to safety and efficacy studies of whole plants used as medicines. No matter the goal of the research, there are some basic housekeeping rules that must be followed to make sure that the results are reliable. The first rule is that the identity of the plant being studied is known and that the correct name is assigned. The second rule is that the material being studied is clean and free of dirt, bacteria, insects, and other plants. The third rule is that the final product is manufactured in a way that maintains the desirable bioactive plant chemicals and minimizes undesirable or harmful plant chemicals. For medicines made from whole or minimally processed plants (often called phytomedicines), the whole plant or its extract is considered to be the drug substance. Unlike single-chemical drugs, plant products are variable because their composition depends on natural variation, geographical origin, weather exposure, harvesting practices, and processing methods. In the U.S. there exist a wide variety of product types ranging from relatively unprocessed dried pieces, powders, and teas made from a single plant species to highly processed concentrates, metabolites, constituents, and extracts of single or multiple plant species. Some highly processed products bear little resemblance to traditional preparations. Different processes used on plants that are nominally the same will predictably result in products that are chemically and biologically different from each other. These sometimes accidental and sometimes intentional changes in composition can result in inconsistent research materials and commercial products that fundamentally different from one another even when the starting plants are the same for each. This talk will provide an overview of concepts and processes important to understanding modern botanical products.
