Based on Traditional Chinese Medicine, auricular acupuncture focuses on points in the ear to help support a wide variety of conditions including trauma, anxiety, PTSD, insomnia, and much more.  There are over 200 points on the ear alone that are believed to correspond to points on the body including physical, and emotional.
Ear seeds are another tool to stimulate these points. They're a safe and effective alternative to acupuncture.
Ear seeds are made from the Vaccaria plant, which is known to stimulate blood flow and energy throughout the body. Because they're worn externally on the outside of the body, ear seeds have a "time-release" effect and stimulate the points through light pressure over long periods. They are often left on for several days, can be worn alone, and clients should press on them several times per day to help stimulate the points.
