Personally, I am against cleansing, especially when you are unwell. The only way to cleanse is when you truly know what you are doing and what minerals to supply your body with during the cleanse. Knowing what minerals is the challenge as with every different cleanse different minerals can be lost...the worst thing you can do when your ill is deplete your minerals. When the body doesn't have the correct proportion of minerals it can't function properly and allergies develop and the organs will begin to use any minerals they can find such as heavy metals, like mercury or lead to perform the lacking minerals duties.
