Chun Pi
What is Chun Pi?
Tree-of-Heaven Bark (chun pi, 椿皮), also known as Cortex Ailanthi, refers to the root bark or stem bark of Ailanthus altissima (Mil.) Swingle. This plant is often found in the China provinces of Shandong, Liaoning, Henan and Anhui. It was introduced to the United States as an ornamental plant in the late 1700s, and has become one of the most prevalent invasive trees in North Carolina.
This plant is typically a small tree, but is able to grow up to 80 feet tall. It has very large leaves, which can measure up to two to four feet long. Its leaves and other parts can release a strong, unpleasant odour that is somewhat similar to burnt peanut butter.
In Traditional Chinese Medicine (TCM), Chun Pi falls under the category of ‘Herbs that stabilise and bind’. Such herbs can treat abnormal discharges and displacement of organs, including conditions such as diarrhoea, abnormal discharges from the vagina, penis or rectum, and prolapse of the uterus or rectum.
