The cause of amenorrhea (absence of menstruation) in women is due to fatigue damaging qi and blood, leading to bodily deficiency. Wind-cold pathogenic factors invade the interior of the uterus (Bao Gong), injuring the Chong Mai (Penetrating Vessel) and Ren Mai (Conception Vessel), as well as the Hand-Taiyang Small Intestine Meridian and Hand-Shaoyin Heart Meridian. This results in the complete obstruction of blood within the uterine collaterals. The Chong and Ren vessels originate from the interior of the uterus and serve as the sea of the twelve meridians. The Hand-Taiyang meridian belongs to the Small Intestine, and the Hand-Shaoyin meridian belongs to the Heart; these two meridians are exterior-interior pairs, governing the transformation of fluids into milk above and menstruation below. When wind-cold injures the blood within the meridians, blood flows freely when warmed but becomes stagnant and closed when cooled. Since it is constrained by wind-cold, blood coagulates internally, causing amenorrhea. It is also stated: "Intestinal rumbling indicates amenorrhea; the root of the disease lies in the Stomach." If Stomach qi is deficient and unable to digest food and drink, jinye (body fluids) cannot generate qi and blood. (Thus, in *Mei Shi Fang*, using only Hou Po (Magnoliae Officinalis Cortex) reveals this principle; see also *Yi Jian Fang*). It is further stated: "Having intercourse while intoxicated exhausts internal qi and injures the Liver, causing menstrual scarcity or cessation." This occurs because the Liver stores blood; excessive fatigue leads to depletion of qi and blood internally. Additionally, prior hemoptysis, hematemesis, or hematochezia constitute "blood loss" (Tuo Xue), named "blood exhaustion" (Xue Ku), which also results in amenorrhea. This happens because jinye (body fluids) are diminished. By replenishing jinye, the menses will naturally resume. A faint and choppy pulse at the Kidney position indicates amenorrhea. Furthermore, a floating pulse at the posterior Guan and inner Chi positions on the left hand indicates Yang exhaustion and absence of the Bladder pulse, leading to menstrual closure. A deep and rapid Liver pulse yields similar findings. Symptoms include difficulty urinating, severe dizziness and headache, lower back pain, cold feet with intermittent pain, and amenorrhea; this may stem from a fall during conception. Prolonged amenorrhea causes blood to coagulate internally, forming masses, transforming into Xue Jia (Blood Masses), or presenting as Xue Zheng (Blood Syndromes). When blood and water merge, causing stagnation and obstruction, and Spleen-Stomach qi is weak, edema may develop. This is because the Spleen corresponds to the muscles of the body and symbolizes Earth; Earth controls Water. When water and blood merge, if Spleen qi is weak and fails to control Water, fluid overflows and infiltrates the muscles, resulting in swelling and fullness.
