1. Kalmegh for Inflammatory Conditions

Kalmegh contains the potent compound andrographolide, which research shows has anti-inflammatory and immune-modulating properties.

2. Kalmegh as an Antioxidant

In addition to andrographolide, kalmegh is rich in other antioxidants like flavonoids that combat oxidative stress. Oxidative stress implies cellular damage caused by free radicals and is central to aging and disease. As an antioxidant, kalmegh extract helps preserve crucial cell constituents and protects organs like the liver, kidneys, and brain cells from free radical harm.  

3. Kalmegh for Liver Health  

kalmegh strongly promotes liver health in multiple ways - it stimulates bile acid secretion to improve digestion and eliminate toxins. It also boosts levels of necessary liver enzymes, signifying improved hepatic function. Kalmegh even assists liver regeneration by stimulating protein and nucleic acid synthesis in liver cells after toxic injury or infection.

Andrographolide induces cancer cell death by interfering with cell communication pathways that propagate malignant cells.

Traditional Ayurvedic medicine has long used kalmegh as a natural fever reducer. Compounds present in the herb limit the production of inflammatory mediators (cytokines), which promote fever generation. This helps lower body temperature in infectious fevers.

6. Kalmegh for Diabetes Management  

Human and animal studies show kalmegh extracts lower blood glucose levels and boost insulin secretion and sensitivity. Though not a replacement for standard treatment, kalmegh appears to help manage high blood sugar in diabetes when taken along with other diabetic medication.

7. Kalmegh for Healthy Digestion

Kalmegh increases secretion of bile acids and gastric juices, leading to better digestion of food. At the same time, its antispasmodic action helps relax intestinal muscles, alleviating cramps, bloating, and constipation issues. The herb also protects the GI lining and stimulates gut-friendly microbe growth.
