One of the more interesting ways of taking an herb in Chinese medicine is the topical tincture. Herbs are soaked in liquor for a period of several months. The liquid is filtered and applied to the skin for a variety of conditions. The advantage of applying a medicine topically to an affected area is that compared to drinking an herbal concoction, there is less risk of adverse systemic affects, such as allergies or interactions with other medicines. This particular mixture is modified from a traditional formula used by martial artists to help them recover from the constant injuries they suffered as a result of their strenuous physical conditioning.
