Clearly urine is not toxic, although some end substances might be
present in urine in small amounts, especially if one is ill. This
small amount of end substances possibly contributes to the
effectiveness of urine therapy. If these triggering substances enter
the body, the body's defense mechanisms are called into action
(immune system). If substances, which leave the body via the urine,
are the same as those involved in the illness process, they can
stimulate the defense system to attack and in this way urine therapy
has proven so helpful in treating allergies.
A similar process takes place when a person is vaccinated against
certain disease, in which case, a small amount of poisonous
substances is injected into a healthy body. This stimulates the
immune system to manufacture antibodies (and thus defend the body),
and could be called a homeopathic or isopathic effect. The practice
of drinking and massaging with urine allows the antibodies, greater
access to the body, which stimulates the immune system. The possible
significance of urea and glutamine for the immune system is earlier
discussed.
Abele suggests that the presence of antigens and antibodies in urine
strengthens the immune system when urine is re-introduced into the
body. The re-introduction of small amounts of bacteria or parasites
found in urine may stimulate the production of IgE. IgA (a virus
inhibiting substance that prevents micro-organisms from becoming
embedded in the mucous) also plays a role here. IgA is found in
mucous and in excretions of body, and therefore also in urine. Urine
therapy increases the production of IgA which possibly explains why
this therapy has a positive effect on infections of the urinary
passages and the kidneys while other treatments offer little relief.
