Sanyinjiao is one of the pre-eminent
acupuncture points. As its name states it is the meeting
point of the three Yin channels of the leg... the
Spleen, the Liver and the Kidney channels.
Sanyinjiao is especially useful
as a 'balancing' point. That is whatever the disharmony,
the action of Sanyinjiao is to bring things
back into balance regardless whether the disharmony
is an excess or a deficiency. This quality, along
with its strong effect on all three Yin organs of
the leg gives it an extraordinarily broad range of
While its main action is on the Spleen,
it also has a strong effect on both the Liver and
Its main function is to harmonize the
Spleen in all its functions. Not only is the Spleen
responsible for the transformation and transportation
of Qi in the body, it is also responsible
for 'keeping things in their place'... referring to
organs in their proper place, blood within arteries
and veins, etc.
Sanyinjiao then is indicated
for undigested food in the stool, diarrhea, abdominal
distention and fullness, borborygmus and other such
It is indicated for blood deficiency
arising out of Spleen inability to provide adequate
Qi to the body, manifesting as palpitations,
blurred vision, painful menstruation, and postpartum
It is indicated for conditions arising
out of the Spleen's failure to 'hold things in their
place', such as uterine bleeding, hernia, uterine
A deficient Spleen makes the body susceptible
to dampness, whether accompanied by heat or cold,
manifesting as heaviness of the body, heaviness of
the limbs, and especially in the lower jiao
manifesting as diarrhea, leucorrhoea.
The three yin channels of the leg all
pass through and the genital area. Sanyinjiao
is the distal point of choice for virtually any disharmony
involving any gynecological disorder, menstruation,
conception, leucorrhoea, and the external genitals.
However, because if its ability to induce
labour, and expel a dead foetus it is generally contraindicated
during an otherwise healthy pregnancy.
Sanyinjiao is an important
point in the treatment of any sexual disorder in both
women and men including pain and contraction, seminal
emission, impotence, and excessive sexual drive.
Most urinary disorders including difficult
urination, retention of urine, enuresis (bed wetting),
& cloudy urine, can all be treated with Sanyinjiao.
is not restricted to the Lower Jiao. It is often indicated
for treatment of insomnia. The Spleen's involvement
is explained by the fact that the Spleen is responsible
for the Transformation and Transportation of Qi.
Disharmonies arising out of Qi deficiency, or Qi and
Blood deficiency, in other parts of the body can be
traced back to the Spleen. An essential part of the
treatment for any disharmony diagnosed as a deficiency
of Qi or Qi and Blood, would include
fortifying the Spleen.
Finally, it is an essential assumption
of TCM diagnosis that everything is connected to everything
else in the body. At the centre of everything is the
Spleen. It is the organ responsible for producing
the 'motive force' of the body, Qi. Sanyinjiao
is the single most important point for balancing the
Spleen, not only regarding its ability to do its job,
but in its relationships with other organs.
