People do not realize how much rotten waste is trapped in the cells of the human body. When a person "FAST" their body odor can chase away anyone, the rotten waste is expelled anyway the body can get rid of it, the breath can be the worse as well as the feet, etc.
People who not experinced will wonder why they feel this and that and wonder if the herbs are doing harm. experince will always be your best teacher and I always suggest reduing your dosage when in doubt, you have the rest of your life, do not get in a big hurry. Learning to correct the diet is goal one.
