According to traditional Chinese medicine (TCM), different areas of our ears correspond to different organs and systems within the body. Stimulating these parts can treat ailments in those various organs and systems. That’s the gist of auriculotherapy, a form of TCM that’s practiced via acupuncture or ear seeds, which are tiny seeds of the vaccaria plant that are stuck onto key points on the ear using adhesive tape. Ear seeds can be left on for up to five days (you can shower and sleep as usual), but they may fall off sooner, depending on where they’ve been placed.
