No one should be handling and using H2O2 (Hydrogen-Peroxid) for these purposes without understanding what it is and how to safely and effectively handle it. It's already a controlled substance even though it is one of the most powerful and beneficial and natural there are. Making mistakes like this can cause further laws to be put in place. First of all, always use FOOD GRADE H2O2. Always. No other kind is safe to touch the body or put in the body. Secondly, very small amounts are needed. Please go to this link which is a free online pdf file which is a huge resource on H2O2 (Hydrogen-Peroxid) called "TheTruthAboutFGHP.pdf. (https://docs.google.com/file/d/0B4tXX-29p_D2Ql9TOHRVTjRHdUk/edit). I've done many enemas using intuitive readings. Most of the time I get 18 or so drops of 35% H2O2 (Hydrogen-Peroxid) per gallon but this can vary according to what my bodymind knows is priority. I use up the whole gallon in one sitting each time which means 2 to 4 retentions for me. I've never had a problem because I always go with intuitive readings which ALWAYS find priority health action since I ask what is the priority health action? from a list of all health actions that I am versed in. When enema comes up I have a list of the ingredients from straight distilled water to various other additives such as apple cider vinegar, essential oils, juices of various kinds (like lemon), and of course H2O2. Once you know how to glean information from the bodymind accurately you never have any of these sort of problems and you rely less and less on so called expert opinions. Just make sure that you are well read on the subject and start small. Even one drop of H2O2 might be too much at a certain time or an enema at a certain time may be entirely the wrong thing. So know about enemas and how and when to use them.
