Vrikshamla
Also known as: Vrikshamla, Kokum, Malabar tamarind, Garcinia cambogia
Overview
Vrikshamla refers to the fruit of Garcinia cambogia, a tropical plant native to Southeast Asia and India, widely recognized for its use in weight management and metabolic health. Its primary active compound is hydroxycitric acid (HCA). Traditionally, it has been utilized in Ayurvedic medicine to address obesity (Sthaulya) and associated metabolic disorders like dyslipidemia. In modern dietary supplements, Vrikshamla is primarily marketed for its potential to aid in weight reduction and improve lipid profiles. While research on Garcinia cambogia extracts, particularly HCA, is moderately mature with several clinical trials and some systematic reviews, high-quality meta-analyses specifically focusing on Vrikshamla are limited. The evidence quality varies, with some studies indicating positive effects, though many are constrained by methodological limitations or small sample sizes.
Benefits
Vrikshamla demonstrates evidence for several benefits, primarily in metabolic health. Its main effects include modest weight reduction and decreased body circumferences, typically observed after 60-90 days of supplementation (e.g., 500 mg twice daily). These effects have been noted in clinical trials, both when Vrikshamla is used alone or as part of multi-herbal formulations. Furthermore, it has shown potential in improving lipid profiles, specifically reducing serum cholesterol and triglycerides, suggesting a role in managing dyslipidemia. Secondary benefits include appetite suppression and inhibition of lipogenesis, both attributed to its HCA content. There are also indications of improvements in metabolic syndrome parameters, such as blood pressure and BMI. These benefits are most relevant for adults with obesity or features of metabolic syndrome, as indicated by clinical trials with sample sizes ranging from 30 to 60 participants. Studies report statistically significant reductions in these parameters (p < 0.05), although the exact effect sizes are often modest and not always clearly quantified.
How it works
The primary mechanism of action for Vrikshamla is attributed to hydroxycitric acid (HCA), which inhibits the enzyme ATP citrate lyase. This enzyme is crucial in converting citrate to acetyl-CoA, a precursor necessary for fatty acid synthesis. By inhibiting this process, HCA effectively reduces lipogenesis, thereby decreasing the body's ability to store fat. Additionally, HCA is believed to suppress appetite, possibly by increasing serotonin levels in the brain, which can lead to reduced caloric intake. It also appears to enhance fat oxidation and improve overall lipid metabolism. In Ayurvedic terms, Vrikshamla possesses properties such as Deepana (digestive stimulant), Pachana (digestive), and Medohara (fat reducing), which align with its observed modern metabolic effects. The bioavailability of HCA is moderate, with absorption efficiency varying depending on the specific formulation.
Side effects
Vrikshamla is generally considered safe when consumed at recommended doses (up to 1000 mg/day of extract or 2 g/day of powder) for short durations, typically up to 3 months. The most commonly reported side effects are mild and include gastrointestinal discomfort, nausea, and headache, affecting less than 5% of users. No significant drug interactions or contraindications have been consistently reported in the clinical trials reviewed. However, specific safety data regarding its use during pregnancy, lactation, or in children are not well established, and therefore, its use in these populations is not recommended without medical supervision. Individuals with pre-existing liver conditions should exercise caution, although direct evidence of liver toxicity is rare and often associated with products containing multiple ingredients or exceeding recommended dosages.
Dosage
Clinical studies on Vrikshamla typically utilize doses of 500 mg twice daily, either as a standalone powder/extract or as part of a polyherbal formulation. These dosages have been administered for durations ranging from 60 to 90 days. The minimum effective dose appears to be around 1 gram per day of Vrikshamla powder. For optimal efficacy, it is generally recommended to administer Vrikshamla before meals, which may help in appetite reduction and improved digestion. While no specific cofactors are required for its absorption or action, adherence to a balanced diet and a healthy lifestyle is crucial for maximizing its potential benefits. The optimal dosing and the maximum safe dose for long-term use are not yet fully defined due to the limited availability of high-quality, long-term clinical data.
FAQs
Is Vrikshamla effective for weight loss?
Clinical trials indicate that Vrikshamla can lead to modest weight loss and reductions in body circumference over 2-3 months of consistent use, particularly when combined with a healthy lifestyle.
Is Vrikshamla safe to use?
Vrikshamla is generally considered safe for short-term use (up to 3 months) at recommended doses, with mild side effects like gastrointestinal discomfort being rare. Long-term safety data is limited.
How long does it take to see results from Vrikshamla?
Benefits such as weight reduction and improved lipid profiles are typically observed after 60 to 90 days of consistent daily supplementation.
Can Vrikshamla improve cholesterol levels?
Some research suggests that Vrikshamla may help improve lipid profiles, including reductions in serum cholesterol and triglycerides, contributing to better metabolic health.
Should Vrikshamla be taken alone or in combination with other supplements?
Vrikshamla has been studied both as a standalone supplement and as part of polyherbal formulations. Its efficacy can be observed in both contexts, depending on the specific health goals.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC7329718/ – This randomized controlled trial investigated a multi-herbal formulation containing Vrikshamla. It found significant reductions in body circumferences and skinfold thickness over 90 days, suggesting efficacy in weight management. However, the small sample size and the use of a combination product limit the ability to isolate Vrikshamla's specific effects.
- https://ayushdhara.in/index.php/ayushdhara/article/view/930 – This case report detailed the use of Vrikshamla (2 g/day) over 60 days, showing improvements in dyslipidemia and subjective obesity parameters. While it suggests potential benefits, its quality is low due to being a single case study without a control group, providing only anecdotal evidence.
- https://www.iamj.in/posts/images/upload/2202_2208.pdf – This open-label clinical trial with 60 participants demonstrated significant reductions in BMI, body weight, and lipid profile parameters with 500 mg twice daily of Vrikshamla over 60 days. Despite showing positive results, the study's quality is moderate due to the lack of a placebo control group and its open-label design.
