Background: Hyperlipidemia is a condition involving abnormally high levels of lipids in the blood. Hyperlipidemia is a major risk factor for cardiovascular diseases and refers to either high levels of triglycerides (TGL) or cholesterol. Herbal supplements have been used in the management of cholesterol levels in Ayurveda, a complete medical system originating in India. KaraHeart is a multi-herbal extract synergistic blend that may help in the management of healthy cholesterol levels. The current study tested the efficacy, tolerability, and safety of KaraHeart versus a placebo in the management of cholesterol levels of patients with mild hyperlipidemia.

Methods: This was a randomized, double-blind, parallel, and placebo-controlled study. A total of 100 patients were divided into two groups. One group was given KaraHeart and the other group was given a placebo for 120 days. Treatment results were assessed by checking the lipid profile parameters such as total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), very-low-density lipoprotein (VLDL), and TGL.

Results: The study found that the herbal supplement KaraHeart significantly reduced levels of LDL, VLDL, TGL, and total cholesterol, while increasing the levels of HDL in the blood. Additionally, the study concluded that KaraHeartwas safe to use.

Conclusions: KaraHeart was shown to be safe and effective in the management of cholesterol levels.
