I use the Chi machine for emotional and stress clearing at least twice a week. At onset of menses, it can feel like a heavy cloak descends on my being. After treatment, this feeling lightens and cramps are lessened considerably. PMS and perimenopausal symptoms. Menstrual cramps, anxiety, mood swings (I bought my first CHI machine 6 years ago for a knee injury that it helped heal and discovered it for this use, which I continue use). (Body) place around abdomen – area of cramps for 5 minutes. Move to different areas. (Mind) treat the 7 chakras, 1 minute each. (Spirit) over thymus and on balls of feet. Sweep entire body. Cramps dissipate, emotions balance out. Feel calm and centered. Usually only need to treat once during cycle. If needed, repeat procedure. Optimism.
