This is my first purchase with Oxyhealth as it seemed like the place to purchase products from "Globalhealingcenter" in Europe. The service was overall good and quite fast, and the products arrived in a perfect condition. The only thing that I am wondering about is whether there are instructions and guidelines that are supposed to come with the cleansing packs like "colon cleanse" or "liver cleanse" as I watched reviews about certain cleanses being provided with instructions that explain everything in detail such as the types of food to be eaten during the cleanse, etc. I personally find it vital to receive the instructions especially when it comes to these cleanses and find it's in the best interest of each individual doing the cleanse.
