Herbal Clean highly recommends the use of PreTox Master Concentrated Capsules as a preliminary cleanse prior to Master Tea Flush. Urinate as often as possible. This is an important step in the cleansing process. Drink plenty of water the several days prior to your Quick Flush. Avoid all unwanted toxins for 24-48 hours prior to the time you desire to be clean. (The longer the better!) Results may be temporary, TIME IT CAREFULLY!
