I have had my parasites treated successfully using Cold Laser (Low Level Laser) treatments at various freqs. My guy has used a low of 1200Hz to a high of 50,000Hz, using this devise...Erchonia PL5000 3LT Laser. I had approx 10 treatments that lasted from 45-90 min. I felt amazing results after the first few sessions. I was very ill when I started, now I feel so much better, not perfect, but an amazing improvement.
