Kalmegh (Andrographis paniculata) is a herb commonly used in Ayurvedic and traditional Chinese medicine. It is believed to have a wide range of benefits, including boosting the immune system, reducing inflammation, and improving liver function. Studies have shown that Kalmegh can help to boost the immune system by increasing the number of white blood cells and helping to fight off infections. It is also thought to have anti-inflammatory properties and may be useful in reducing inflammation and pain in conditions such as osteoarthritis and rheumatoid arthritis. Additionally, Kalmegh is believed to have hepatoprotective properties and may be useful in treating liver disease and improving liver function. It is also considered to be an adaptogen, which means that it can help the body cope with stress. It is also believed to have antioxidant properties and may be useful in preventing cellular damage. Kalmegh is considered safe, but it's always recommended to consult an Ayurvedic practitioner before using it.
