Guggul, a resin extracted from the Commiphora mukul tree, has a longstanding history of use in Ayurvedic medicine for promoting fat metabolism and managing lipid disorders. Traditionally, it has been used to treat "medoroga" (obesity and lipid disorders) due to its purported ability to "scrape" excess fat from the body. In the modern context, several scientific studies have investigated guggul’s effect on lipid metabolism, focusing primarily on its active component, guggulsterone. Early research suggested that guggulsterone might stimulate thyroid function and influence cholesterol metabolism, leading to reductions in total cholesterol, LDL cholesterol, and triglycerides. However, more recent and rigorous clinical trials have produced mixed results. While some studies have found modest improvements in lipid profiles, others have failed to replicate these findings or have observed no significant effect compared to placebo. A 2003 randomized controlled trial published in the Journal of the American Medical Association found no significant benefit for cholesterol reduction and noted some adverse effects. Systematic reviews and meta-analyses generally conclude that the evidence for guggul’s efficacy in supporting fat metabolism is weak to moderate, with inconsistencies and potential safety concerns (e.g., skin rashes, drug interactions). In summary, while guggul is traditionally used for poor fat metabolism and there is some scientific interest, the clinical evidence supporting its efficacy is limited and mixed, leading to a modest evidence score.
