What is Andrographis paniculata?

Andrographis paniculata, the king of bitters, is a mainstay of Ayurvedic and Chinese medicine for fever and infection. Its active andrographolides have some of the stronger clinical support among immune herbs: randomized trials and reviews find standardized extracts can reduce the severity and duration of common colds and upper-respiratory symptoms, often within the first days of illness. It is used short-term at the onset of symptoms rather than continuously. Standardize to andrographolide content, commonly 10 to 30 percent. Avoid in pregnancy and with autoimmune conditions or fertility concerns, and stop if you notice digestive upset.
