Mugwort Leaf (Ai Ye): A Warming Herb for Cold, Bleeding, and Damp Conditions
Introduction
Mugwort leaf, known as Ai Ye (艾叶) in Traditional Chinese Medicine (TCM), is a warming, acrid, and bitter herb used to stop bleeding, warm the uterus, and dispel cold and dampness. It is particularly famous for its use in moxibustion therapy, where its heat-activating properties are applied externally. Internally, it is used for menstrual disorders, cold abdominal pain, and skin conditions. Its strong warming and moving nature makes it a vital herb for cold-related gynecological and digestive imbalances.
What Is Mugwort Leaf?
Ai Ye is derived from the dried leaves of the Artemisia argyi plant, a fragrant perennial native to China and East Asia. In TCM, it is classified as bitter, acrid, and warm, and it enters the Spleen, Liver, and Kidney meridians. Its warming qualities make it ideal for expelling internal cold, especially in the lower body.
It is used both internally in decoctions and externally in moxibustion or washes, offering a dual-action approach to restoring warmth and circulation while stopping cold-type bleeding.
