Since women anatomically have a uterus and its associated
organs, and physiologically have menstruation, leukorrhea,
pregnancy, labor and breast- feeding, there is an expected
difference between women and men in terms of zang-fu organs,
channels and collaterals, yin and yang, and qi and blood in their
physiological activities of reproduction.
The human body takes the zang-fu organs, and the channels and
collaterals, as the fundamentals, and performs its function through
qi and blood. The five aspects of menstruation, leukorrhea,
pregnancy, labor and breast-feeding are manifestations of the
transforming function of zang-fu organs, channels and collaterals,
and qi and blood.
