Andrographis
A bitter herb used in traditional medicine to support immune function and relieve cold symptoms.
Also known as: Andrographis paniculata • King of Bitters
Overview
Andrographis paniculata, commonly known as the "King of Bitters," is an herb that has been used for centuries in traditional Ayurvedic and Chinese medicine. It is well-known for its extremely bitter taste, which is attributed to its active compounds, called andrographolides. Andrographis is primarily used to support the immune system and to relieve symptoms of the common cold, such as sore throat, cough, and fever. It is believed to have anti-inflammatory, antiviral, and antibacterial properties. Modern research has begun to investigate the traditional uses of andrographis, and some studies have shown promising results. It is thought to work by stimulating the immune system and by inhibiting the growth of viruses and bacteria. In addition to its use for colds and flu, andrographis has also been studied for its potential benefits in other conditions, such as inflammatory bowel disease and rheumatoid arthritis. However, more research is needed to confirm these effects and to determine the optimal dosage and long-term safety of andrographis supplementation.
