Earthworm (Prepared) Chinese Herb
Earthworm (Prepared) (Di Long): A Channel-Unblocking Herb for Spasms, High Fever, and Swelling
Introduction
Prepared earthworm, known as Di Long (地龙) in Traditional Chinese Medicine (TCM), is a unique medicinal substance used to clear heat, open the channels, stop spasms, and calm wheezing. Salty and cold in nature, Di Long is most commonly used in cases of high fever with convulsions, hot joint pain, stroke recovery, and urinary difficulty. Though unusual in modern wellness circles, it remains a powerful agent for addressing heat and stagnation in the body.
What Is Prepared Earthworm?
Di Long refers to the dried body of Pheretima aspergillum, a species of earthworm used in TCM. It is typically processed and dried before being powdered or sliced for use. In TCM, it is classified as salty and cold, entering the Bladder, Liver, Lung, and Spleen meridians. Earthworm is traditionally used to drain heat, unblock channels, promote urination, and settle internal wind—making it especially helpful for stroke, seizures, and inflammation-related symptoms.
