Look up dr. Richard Schulze ,on internet he practiced 20 years.Do not use epson salts.you must get your colon working at least 2 times a day before using any cleaner.iI have followed schulze over 15 years and seen no doctor in 50 years. 2 doctors almostdid away with me my younger brother died at 39 cause doctors wouldnt listen.My mother walked in to the hospital saying she thought she was having a heart attack. doctor admitted she was having a slight heart attack.So they took away both hearing aids making her deaf.took away her glasses making her blind . Put her among the dying,and expensive area.she couldnt see couldnt hear all she felt was the vibrations of the heart pumps. THEY scared her to death.DR Schultz you can trust.I cured myself of prostate cancer because I followed his writings. chuck witkowski
