Guggul
Parts Used & Where Grown
The mukul myrrh (Commiphora mukul) tree is a small, thorny plant distributed throughout India. Guggul and gum guggulu are the names given to a yellowish resin produced by the stem of the plant. This resin has been used historically and is also the source of modern extracts of guggul.
How It Works
Guggul contains resin, volatile oils, and gum. The extract isolates ketonic steroid compounds known as guggulsterones. These compounds have been shown to provide the cholesterol- and triglyceride-lowering actions noted for guggul.1 Guggul significantly lowers serum triglycerides and cholesterol as well as LDL and VLDL cholesterols (the “bad” cholesterols).2 At the same time, it raises levels of HDL cholesterol (the “good” cholesterol). As antioxidants, guggulsterones keep LDL cholesterol from oxidizing, an action which protects against atherosclerosis.3 Guggul has also been shown to reduce the stickiness of platelets—another effect that lowers the risk of coronary artery disease.4 One double-blind trial found guggul extract similar to the drug clofibrate for lowering cholesterol levels.5 Other clinical trials in India (using 1,500 mg of extract per day) have confirmed guggul extracts improve lipid levels in humans.6
A combination of guggul, phosphate salts, hydroxycitrate, and tyrosine coupled with exercise has been shown in a double-blind trial to improve mood with a slight tendency to improve weight loss in overweight adults.7
One small clinical trial found that guggul (Commiphora mukul) compared favorably to tetracycline in the treatment of cystic acne.8 The amount of guggul extract taken in the trial was 500 mg twice per day.
