As of 2015, Hoodia has not been evaluated by the FDA for safety, and all potential risks may not be known, explains Drugs.com. There is no data suggesting adverse effects, according to Adrienne Youdim, MD, director of the Comprehensive Weight Loss Program at Cedars-Sinai Medical Center, reports WebMD.
Patients with diabetes, heart problems, blood clotting disorders or anorexia, bulimia or other eating disorders are advised not to take Hoodia without first speaking with their doctor, warns Drugs.com. Children and patients that are pregnant or could become pregnant, should also consult their physician prior to use. Citing the uncertainty of hoodia and its wide availability, president of American Herbal Products Association Michael McGuffin suggests patients buy a reputable brand from a reputable store, reports WebMD.
