"An important characteristic of the Hubbard detoxification program is the use of niacin. Niacin has the well-known effect of causing "vasodilation", often called the niacin flush, which is an opening of the small blood vessels, the capillaries, so that more blood flows through them. These are the blood vessels which are of most value in reaching fatty tissues.In this way the toxins which are stored in these fatty tissues can be removed, into the bloodstream, and processed out of the body"
