Although Hoodia was discovered relatively recently, the San Bushmen of the Kalahari desert have been eating it for a very long time. The Bushmen, who live off the berth, would cut off part of the Hoodia stem and eat it to ward off hunger and thirst during nomadic hunting trips. They also used Hoodia for severe abdominal cramps, haemorrhoids, tuberculosis, indigestion, hypertension and diabetes.
In 1937, a Dutch anthropologist studying the San Bushmen noted that they used Hoodia to suppress appetite. But it wasn't until 1963 when scientists at the Council for Scientific and Industrial Research, South Africa's national laboratory, began studying Hoodia. Initial results were promising lab animals lost weight after taking Hoodia. The South African scientists, working with a British company named Phytopharm, isolated the active ingredient in Hoodia, a steroidal glycoside, which they named p57. After receipt a patent in 1995, they licensed P57 to Phytopharm. Phytopharm has spent more than $20 million on Hoodia research.
Hoodia appears to suppress appetite. Much of the buzz about Hoodia started after 60 Minutes correspondent Leslie Stahl and crew traveled to Africa to try hoodia. They hired a local Bushman to go with them into the desert and track down some Hoodia. Stahl ate it, describing it as cucumbery in texture, but not superlative. She lost the desire to eat or drink the entire day. She also didn't experience any going on side effects, such as indigestion or heart palpitations. Stahl concluded, "I'd have to pronounce it did work."
