Injuries inside the throat that prevent swallowing can be treated by taking one egg, drilling a hole to remove the yolk and keeping the white, adding a piece of raw Pinellia, and simmering it over low heat until cooked. Consuming the egg white will heal the injury. This also proves that throat injuries caused by knives or needles can be treated with raw Pinellia and egg white, which have the ability to heal wounds and alleviate pain.
