Leslie
Stahl, of CBS News, reported on hoodia last year. In fact she ate it. She said
that she had no after effects no funny taste in her mouth, no queasy
stomach, and no racing heart. She also wasn't hungry all day, even at mealtime.
She also reported that she had no desire to eat or drink the entire day. "I'd
have to say it did work," says Stahl.
The Bushmen of the Kalahari have
been eating hoodia for a very long time. The first scientific investigation of
the plant was conducted at South Africas national laboratory. Because
Bushmen were known to eat hoodia, it was included in a study of indigenous
foods.
"What they found was when they fed it to animals, the animals
ate it and lost weight," says Dr. Richard Dixey, who heads an English
pharmaceutical company called Phytopharm that is trying to develop weight-loss
products based on hoodia.
It took the South African national laboratory
30 years to isolate and identify the specific appetite-suppressing ingredient
in hoodia. When they found it, they applied for a patent and licensed it to
Phytopharm.
Phytopharm had spent more than $20 million on research by
late 2004, including clinical trials with obese volunteers that have yielded
promising results. These volunteers ended up eating about 1,000 calories a day
less than those in the control group. Consider that the average American man
consumes about 2,600 calories a day and woman about 1,900. "If you take this
compound every day, your wish to eat goes down. And we've seen that very, very
dramatically," says Dixey.
But be careful... no one has demonstrated
that the resulting product is safe. And many products claiming to contain
hoodia only have minute amounts of the active ingredient.
