Salacia reticulata improves serum lipid profiles and glycemic control in patients with prediabetes and mild to moderate hyperlipidemia: a double-blind, placebo-controlled, randomized trial.

The present randomized, double-blind, placebo-controlled study evaluated the efficacy and safety of Salacia reticulata leaves and root bark extracts in 29 patients with prediabetes and mild to moderate hyperlipidemia. Patients received either Salacia extracts (500 mg/day) or placebo along with therapeutic lifestyle changes for a period of 6 weeks. Efficacy was evaluated in terms of change in lipid profile and glycemic levels. The safety and tolerability was evaluated by a physical examination and clinical laboratory evaluations. Improvements in lipid profiles and glycemic levels were observed in Salacia extract-treated groups when compared to placebo at week 6. A statistical significant reduction was observed in low-density lipoprotein cholesterol and fasting blood sugar (FBS) levels at week 3 and 6 when treated with root bark extract. The leaves extract-treated group showed statistically significant reduction in FBS levels at week 6 only. No adverse events occurred and all safety parameters were within normal ranges during the study. This study revealed that treatment with S. reticulata was safe and well-tolerated and may be beneficial in the management of prediabetes and mild to moderate hyperlipidemia.
