Ginger is effective in treating facial palsy caused by wind-cold attack, qi deficiency and blood stasis, and phlegm-dampness obstruction, but it is less effective in treating facial palsy caused by wind-heat attack, and may even aggravate the condition. The following precautions should be taken when applying ginger to treat facial palsy: 1. The thickness of the ginger slices should be about 2 cm, and several small holes should be made on the ginger surface for heat penetration; 2. Place the ginger slices on the affected area of the face, light the moxa pillar, and pad with another ginger slice if necessary; 3. Since the patient’s facial nerve is paralyzed, the temperature sensation is changed, so care should be taken to prevent burns.
