Abstract
Gum guggul extracts (GGEs) are botanical preparations derived from the oleoresin of the Commiphora mukul tree. The preparations are traditionally used in Ayurvedic medicine to treat hyperlipidemia, obesity, diabetes, atherosclerosis, and inflammatory conditions such as arthritis. In the United States, GGEs are marketed as dietary supplements. GGE toxicity was evaluated due to widespread human exposure through increasing dietary supplement use, demonstrated metabolic and hormone-altering effects, and a lack of available information to adequately assess safe use in humans. Male and female Sprague Dawley (Hsd:Sprague Dawley SD) rats and B6C3F1/N mice were administered a GGE formulation in corn oil by gavage for 28 days or 3 months. Oral gavage was chosen as the route of exposure for these studies because human exposure primarily occurs by ingestion of encapsulated GGE supplements. (Abstract Abridged).
