Although it has received considerable media attention purporting its effects on weight loss, there is liver toxicity associated with commercial preparations of the fruit extract with clinical evidence indicating it has no significant effect on weight loss.

Cultivation

Garcinia gummi-gutta is grown for its fruit in Southeast Asia, coastal Karnataka/Kerala, India, and west and central Africa. It thrives in most moist forests.
G. gummi-gutta is one of several closely related Garcinia species from the plant family Clusiaceae. With thin skin and deep vertical lobes, the fruit of G. gummi-gutta and related species range from about the size of an orange to that of a grapefruit; G. gummi-gutta looks more like a small yellowish, greenish, or sometimes reddish pumpkin. The color can vary considerably. When the rinds are dried and cured in preparation for storage and extraction, they are dark brown or black in color.
Along the west coast of South India, G. gummi-gutta is popularly termed "Malabar tamarind", and shares culinary uses with the tamarind (Tamarindus indica). The latter is a small and the former a quite large evergreen tree. G. gummi-gutta is also called goraka or, in some areas, simply kattcha puli (souring fruit). It is called uppage in Kannada language and fruits are collected and dried for selling to dealers in Sirsi, Karnataka.
Cooking
G. gummi-gutta is used in cooking, including in the preparation of curries. The fruit rind and extracts of Garcinia species are called for in many traditional recipes, and various species of Garcinia are used similarly in food preparation in Assam (India), Thailand, Malaysia, Burma, and other Southeast Asian countries. In the Indian Ayurvedic medicine, "sour" flavors are said to activate digestion. The extract and rind of G. gummi-gutta is a curry condiment in India. It is an essential souring ingredient in the southern Thai variant of kaeng som, a sour curry.
G. gummi-gutta is used commercially in fish curing, especially in Sri Lanka and South India. The trees can be found in forested areas and also are protected in plantations otherwise given over to pepper, spice, and coffee production.
Weight loss
Hydroxycitric acid (HCA), the principle constituent (10-50%) of the dried fruit rind of Garcinia cambogia, has been assessed for its potential to cause weight loss. In late 2012, a United States television personality, Dr. Oz, promoted Garcinia cambogia extract as "an exciting breakthrough in natural weight loss". Dr. Oz's endorsements of dietary supplements having no or little scientific evicence of efficacy have often led to a substantial increase in consumer purchases of the promoted products.
However, medical evidence is lacking, and the results of clinical trials do not strongly support claims that extracts derived from Garcinia cambogia are effective weight-loss aids. Meta-analyses of clinical trials offers evidence for limited short term weight loss with increases of up to two-fold in adverse events. A 1998 randomized, controlled trial looked at the effects of hydroxycitric acid, the purported active component in G. gummi-gutta, as a potential antiobesity agent in 135 people. The conclusion from this trial was that Garcinia cambogia failed to produce significant weight loss and fat mass loss beyond that observed with placebo. A more recent report stated that a meta-analysis, had clear limitations, suggesting:
…a small, statistically significant difference in weight loss favouring HCA over placebo (MD: −0.88 kg; 95% CI: −1.75, −0.00). [but with] Gastrointestinal adverse events… twice as common in the HCA group compared with placebo in one included study… [leading them to conclude that while] ...Garcinia extracts/HCA can cause short-term weight loss. The magnitude of the effect is small, and the clinical relevance is uncertain.
Further, adverse events associated with use of such supplements ("side effects") — especially, hepatotoxicity, as well as gastrointestinal issues — led to one preparation being withdrawn from the market.
While it has received considerable media attention purporting impact on weight loss, the limited clinical evidence for Garcinia cambogia supports no clear effect, while gastrointestinal adverse events were two-fold more common over the placebo in a 2011 meta-analysis indicating the extract may be unsafe for human consumption.
Adverse effects
Orally, 500 mg of hydroxycitric acid four times daily can cause nausea, gastrointestinal discomfort, and headaches.
Drug Interactions
There have been several case reports of patients developing "Serotonin Syndrome" after combining their serotonergic medicines with Garcinia cambogia. Caution should be exercised in patients treated with the following class of medications who are looking to manage their weight issue using Garcinia cambogia:
