Hoodia is a succulent plant native to Southern Africa, traditionally used by indigenous people to suppress hunger during long hunting trips. To use, follow the recommended dosage on the product label. Hoodia is believed to work by mimicking the effects of glucose on nerve cells, signaling the brain that the body is full. The effectiveness of Hoodia varies among users, with some reporting results within weeks. Side effects may include dry mouth, dizziness, and potential interactions with certain medications.
