Ameliorative effects of herbal combinations in hyperlipidemia

Area of Science:

• Ayurvedic medicine
• Pharmacology
• Nutraceuticals

Background:

• Traditional Indian Ayurvedic plants like Glycyrrhiza glabra, Withania somnifera, Asparagus racemosus, Chlorophytum borivilianum, and Sesamum indicum are used for various ailments.
• Previous research suggests these plants possess hypolipidemic and antioxidant properties.

Purpose of the Study:

• To investigate the combined effects of these five Ayurvedic plants on hypercholesterolemic rat models.
• To evaluate the impact of different plant combinations on lipid metabolism and oxidative stress.

Main Methods:

• Hypercholesterolemic rats were administered three different combinations of plant extracts (5 gm% for four weeks).
• Evaluated plasma and hepatic lipid profiles, fecal excretion of sterols and bile acids.
• Assessed hepatic HMG-CoA reductase activity, bile acid content, and antioxidant status (catalase, SOD, ascorbic acid).
• Measured hepatic lipid peroxidation and plasma total antioxidant capacity.

Main Results:

• All three plant combinations significantly reduced plasma and hepatic lipid profiles in hypercholesterolemic rats.
• Increased fecal excretion of cholesterol, neutral sterol, and bile acids was observed.
• Enhanced hepatic HMG-CoA reductase activity and bile acid content were noted.
• Improved hepatic antioxidant status and plasma total antioxidant capacity, with reduced lipid peroxidation.

Conclusions:

• Composite formulations of Glycyrrhiza glabra, Withania somnifera, Asparagus racemosus, Chlorophytum borivilianum, and Sesamum indicum demonstrate significant hypolipidemic and antioxidant effects.
• Combination I exhibited the most pronounced benefits, suggesting a dose-dependent or synergistic relationship among phytocomponents.
• These findings support the therapeutic potential of these Ayurvedic plants in managing hypercholesterolemia and associated oxidative stress.
