Outer canthus itching refers to an uncomfortable, irritating sensation at the outer edge of the eyes. This symptom is characterized by a persistent need to scratch the outer corners of the eyes, often accompanied by redness or swelling.
It can be caused by various factors, including environmental allergens, dry eyes, or infections like conjunctivitis. The sensation of itchiness in this specific area can be bothersome and may interfere with daily activities, prompting individuals to seek relief.
Traditional Chinese Medicine (TCM) approaches outer canthus itching through a lens that differs significantly from Western medicine. In TCM, this symptom is often seen as a reflection of underlying imbalances within the body's energy systems. It is commonly associated with Liver Fire or Wind-Heat in the Liver Channel, leading to irritation and inflammation at the outer corners of the eyes.
TCM practitioners focus on identifying and treating these internal disharmonies, which may involve the use of herbs, acupuncture, and lifestyle adjustments to restore balance and alleviate symptoms.
In TCM, the treatment of outer canthus itching often involves acupuncture, targeting specific points believed to be effective in relieving the symptom. One such acupoint is Tongziliao GB-1, located in the Gall Bladder Channel. This point, found lateral to the outer canthus in the depression on the lateral side of the orbit, is known for its ability to clear Heat in the eyes, expel Wind from the eyes and head, and subdue Liver Yang and Liver Fire.
Stimulating Tongziliao GB-1 can provide relief from the itching and contribute to the overall balance and health of the eyes according to TCM principles. The selection of this and other acupoints is based on a holistic assessment of the individual's condition and the specific patterns of disharmony present.
