- Hoodia is a cactus-like plant that grows in Africa’s Kalahari Desert. Historically, the San Bushmen are believed to have used hoodia to suppress appetite.
- Today, hoodia dietary supplements are promoted as appetite suppressants for weight loss.
- We know very little about hoodia because only one study of this herb has been done in people.
- The one small study of hoodia in people involved women who were overweight. Those who took hoodia for 15 days didn't lose more weight than those who took a placebo.
- Little is known about the safety of hoodia. However, the one completed study in people raises concerns. In that study, participants taking hoodia had more side effects than those taking placebos, including nausea, vomiting, dizziness, and odd skin sensations. Of concern, hoodia significantly affected some clinical and safety parameters, such as blood pressure, bilirubin, and electrocardiogram (heart function) measures.
- Little is known about whether it’s safe to use hoodia during pregnancy or while breastfeeding.
- Whether hoodia interacts with medicines or other supplements is not known.
- Talk to your health care providers about any complementary health approaches before you use. It may be contraindicated with any medications you are currently taking.
