Thanks andre! Gua sha seems to be a winner in practicality, although i probably wouldnt use a coin they are dirty things even after cleaning them , their metallic nature I dont like. But thats just me , and in a situation where you had no spoons or scrapers very practical.
Yesterday at the clinic the bleeding LU11 technique gave instant relief to a TCM student/patient. The topic served to remind what was meant to be done beforehand. Yay for appropriate bleeding.
