They can be very beneficial. The best machine is a gravity flow, hope yours is that. To do some of the other ones you may as well join the circus. lol It is actually relaxing, my therapist used implants... coffee for the liver and whatever she thought was needed at the time..a parasite and yeast kill, oxygen, a blood purifier and last as she called it, the cream rinse ... minerals. There can be some cramping as crud is being pulled out and goose pimples as you detox.
She designed her own machine and was selling them all over the US..quite a few in CO. Doctors sent people to her they had given up on and I saw her save lives.
She was trained by Bernard Jenson and had been in busness 13 years before I learned about her. He has a very good book about the colon that can found in health food stores. Sadly she died a few years ago, she had anuerism.
The thing to do is to have two the first time according to my therapist. The first one sets you up to release toxins and you can be very sick the next day. I know because my GP did not really underatand it all and said to only have one.
People came from all over the US to my therapist and some big names. She was named Woman of the Year in Who's is Who in alternative medicine for two years. She helped me a lot. We became good friends and I miss her. I am sure she was responsible for my 8 year remission.
I still go once in a while to a woman she trained but it is quite far. Some us are trying to get one of her machines here, her assistant was very good and she could come and operate it. We will see.
The world has become so toxic that everyone can benefit from colonics.
My therapist turned around two very sick poeple with MCS, they were both wearing masks when I met them.
Good luck!
