Drainage is the process of detoxifying the body, at cellular level, by opening the routes of elimination and discharging the toxic accumulations. These drainage routes (or emunctories as they were historically called) are separated into two categories:

1. primary, which includes most of the abdominal organs (liver, kidney, intestines, lungs, stomach and pancreas) and
2.  secondary, which includes the other naturally existing routes of elimination such as the skin, mucus membranes, nose and genitals.

In chronic disease, often one or more systems of elimination are blocked or sluggish, which may result in an overload of other systems.

Drainage is distinctly different from “detoxification,” which refers to the removal of extracellular waste products from the liver and colon.
 
Detoxification does not address intracellular toxins that can accumulate in these and other areas of the body. Drainage alone is effective in permanent removal of toxins, and simultaneously works to improve the functioning of weakened systems of the body.

Biotherapeutic Drainage helps to assist the body in optimizing elimination of these waste products. If the impurities are not removed first, lasting health can not be achieved. Therefore, drainage is a way to cleanse and rebalance the system to optimize the function of the immune system and improve overall health.
