In a plumbing system, the ‘U’ bend traps all the debris that passes through the sink, toilet or wash basin. With time, unless proprietary cleaners are used, the bend becomes clogged and waste water cannot flow away properly. The feet are the furthest point in the circulatory system from the heart. They are also the part of the body where the effect of gravity is greatest, and are in effect, the "U’ bend of the body. It is theorized that calcium, uric acid and lymphatic deposits in the blood accumulate in the feet interfering with the normal circulation of blood and lymph.
Reflexology breaks up and moves these deposits, thus improving blood and lymph circulation.
