The Haci Magnetic Acupressure suction cup has 3 components: the Plastic Cup, the magnetic tablet head (Acupressure magnet "needle") and the Negative Pressure bulb. For cupping: Put a small amount of Cupping Herbal Cream (included) on acupoint -- for best results. You may use herbal oil on the skin of point also. Just squeeze the bulb between fingers and put the suction cup on the acupoint or sensitive points on skin, then release bulb to desired pressure. The cup should have enough pressure to stay on the point; if it slips off, squeeze bulb more or use more herbal cream. Laying down or sitting position with cups positioned on points for 15 minutes is recommended. You may do cupping once or twice daily. Caution:do not fall asleep with cups on the body- may cause bruise or blistering. If a bruise appears on the skin, do not use cupping on that point until bruise disappears. Apply some Cupping Herbal Ointment to bruise or blister to assist the healing process. To remove a cup after treatment, pinch the sac (ball) and loose a cup side by side. Don't pull out a cup strongly.
