🌿 Introduction
Kalmegh (Andrographis paniculata) is one of Ayurveda's most valued medicinal herbs and is widely known as the 'King of Bitters' because of its intensely bitter taste. Used for centuries in Ayurveda, Siddha and Traditional Chinese Medicine, Kalmegh is traditionally recommended for supporting immunity, liver function, digestion and recovery from seasonal illnesses. Modern scientific research has identified andrographolide, its major bioactive compound, which possesses antioxidant, anti-inflammatory and immunomodulatory properties. Today Kalmegh is commonly consumed as herbal tea, powder, capsules and standardized extracts.

📉 Glycemic Index
Kalmegh has a very low glycemic index because it contains very little digestible carbohydrate and is consumed only in small medicinal quantities.
🧬 Bioactive Compounds
Kalmegh is exceptionally rich in andrographolide, the compound responsible for most of its medicinal properties. It also contains neoandrographolide, deoxyandrographolide, flavonoids, diterpenoid lactones, polyphenols and various antioxidant phytochemicals that contribute to its immune-supporting and hepatoprotective effects.
💊 Vitamins & Minerals Explained
Although Kalmegh contains calcium, iron, magnesium and potassium, its health benefits primarily come from its diterpenoid compounds rather than its nutritional value because medicinal doses are relatively small.
🕉️ Ayurvedic Properties & Dosha Effect
According to Ayurveda, Kalmegh has an intensely Tikta (bitter) taste with a cooling potency (Sheeta Veerya). It helps balance Pitta and Kapha Doshas, supports healthy liver function, improves digestion, removes excess heat from the body and promotes natural detoxification. Ayurveda also considers Kalmegh beneficial for maintaining healthy skin and supporting recovery during seasonal illnesses.
