What Is Garcinia Cambogia? The fruit Garcinia cambogia was once just the less popular cousin of a trendy fruit the mangosteen. But now nutritional supplements containing Garcinia cambogia extract have become the rage touted for their purported ability to curb appetite and stop weight gain.  The gambooge fruit also known as the Malabar tamarind grows across southwest India Myanmar and Indonesia. It ripens to a red or yellowish fruit about the size of an orange but resembling the shape of a pumpkin. People have long used the dried gambooge rinds for chutneys or curries and sometimes as an aid for stomach problems. But in the late 1960s scientists identified a substance in the rind of the fruit called hydroxycitric acid or HCA which has some potentially attractive qualities. Some studies have shown that HCA stops an enzyme that turns sugar into fat said Catherine Ulbricht senior pharmacist at Massachusetts General Hospital in Boston and co-founder of Natural Standard Research Collaboration which reviews evidence on herbs and supplements. A fruit extract that could interfere with the body's production of fat? The appeal is obvious. However good results in test tubes don't always translate to an entire person.
