Chuan Xin Lian (Andrographis Paniculata)

What Is Chuan Xin Lian

Chuan Xin Lian is also known as Andrographis Paniculata, which is an annual herb belonging to the family Acanthaceae. It is commonly used in Chinese herbal medicine and Ayurvedic medicine with a medicinal history of over 5000 years.

This plant is native to India and Sri Lanka and is now widely distributed in South and Southeast Asia. Indians use it to treat diabetes, dysentery, hepatitis, skin infections, and snake bites. Thai people use it to treat common colds and non-infectious diarrhea.

In the early autumn of each year, people gather the above-ground part of Andrographis paniculata, wash them with water, remove their impurities, cut them into segments, dry them in the sun, and make them into Chinese herbal medicines.
