Korean moxa wheels increase white blood cell count. The marks on her upper back (UB 43) are from the wheels. Very warming, tonifying technique. The wheels below (on UB 23) have needles in the center so the heat can penetrate even more deeply. Moxa on SP 10 also boosts low blood counts. The three huangs* points also have demonstrable laboratory results. Huang Shu = UB 43, which is the tonification point for cases of weakness and deficiency, especially from chronic illness.
