Garcinia

Other Name Gambooge, Brindleberry, Brindall berry, Malabar tamarind
Details

is a subtropical species of Garcinia native to Indonesia. The yellowish fruit is pumpkin-shaped.

   
  Cultivation and uses
Gambooge is grown for its fruit in southeast Asia, and west and central Africa. It thrives in moist forests.
In Indian traditional medicine, this species was prescribed for edema, delayed menstruation, constipation and intestinal parasites. In the form of precoction, it was also used for rheumatism and bowel complaints. The extract and rind of Garcinia cambogia is a curry condiment in India.
Research taking place in 1965 found that hydroxycitric acid (HCA) is the principal active compound in the rind and flesh of gambooge fruits. Although HCA seems to reduce the synthesis of fatty acids and cholesterol in vitro (lipogenesis inhibition), a study in 1998 (Garcinia cambogia (Hydroxycitric Acid) as a Potential Antiobesity Agent, JAMA 280: 1596-1600, by Steven B. Heymsfield, MD, et al.) found no statistically significant difference in weight loss between those given the compound and those given a placebo. Nonetheless, extract from this species is nowadays widely sold as a component of dietary supplements and most recently as Skinny Water.

  Garcinia cambogia, also known as malabar tamarind and brindle berry, is a relatively small purple fruit that contains a chemical compound called Hydroxycitric acid (HCA). HCA is much like a derivative of the same citric acid that can be found in many other citric fruits whose chemical make up is only slightly different. Studies indicate that HCA may assist in weight loss because of its ability to regulate metabolism.
  Specifically, hydroxycitric acid is a competitive inhibitor of adenosine triphosphate-citrate. In the cytosol, ATP citrate lyase catalyzes the conversion of citrate and coenzyme A to oxaloacetate and acetyl coenzyme A (commonly referred to as acetyl CoA). Acetyl CoA is required for the synthesis of fatty acids, cholesterol and triglycerides.
  Oxaloacetate may enter the gluconeogenic pathway, which can lead to the production of glucose and glycogen. Many researchers and experts assert that the putative antiobesity effect of hydroxycitric acid is due to suppression of fatty acid and fat synthesis. Additionally, hydroxycitric acid is believed to suppress food intake via an anorectic effect, which also supports the belief that HCA may assist in weight loss.
   
  Studies suggest that garcinia cambogia may assist in weight loss for the following reasons:
 
  • HCA appears to block the conversion of sugars and starches into fats, that this, HCA is believed to help inhibit fat production.
  • HCA may suppress appetite by raising levels of certain brain chemicals such as serotonin, a key stimulator of appetite.
  However, there is no concrete evidence that supports the conclusion that garcinia cambogia can in fact cause weight loss. However, in a study of 60 overweight participants who took the supplement for 2 months, HCA appeared to help participants lose weight when compared with other study participants who were given a placebo.
   
  Dosage and Administration
While there is no recommended dosage, a normal dosage of HCA would likely be 250 to 1,000 mg taken 3 times per day. The reason that we say 250 to 1,000 mg of HCA as opposed to garcinia cambogia itself is because more products labeled garcinia cambogia are standardized to contain a fixed amount of HCA.
   
  Side Effects
To date no serious side effects involving either garcinia cambogia fruit extracts or the concentrated chemical HCA have been reported.
