The classical Ayurvedic description of menses was more specific; according to the Astanga Hrdayamis, “in women, the rajas (menstrual blood) which is the product of rasa (the first dhatu), flows out of the body for three days, every month, after the age of twelve years and undergoes diminision by the age of fifty years.”4There are many Sanskrit terms that refer to the menstrual cycle.In Sanskrit, “the menstrual cycle of a woman is called rajodarshana.
The hormonal flow between the three glands is a negative feedback system; if the body has enough estrogen then no LHRH is produced, however, if estrogen levels are running low, than the hypothalamus secretes LHRH.
A healthy menstrual cycle is dependent on functioning of the endocrine system.1Every month an egg matures and a woman’s body and uterus prepare for pregnancy.
However, if the egg was not fertilized then production of estrogen and progesterone drops, triggering the shedding of the endometrium-‐ the start of another menstrual cycle.2 This monthly release is the motion of apana vayu.
The subdosha of vata associated with downward movement.
According to Rosemary Gladstar, “many women have waited for months, even years, for their menstrual cycle to return after having been on birth control pills for an extended period of time.”15A woman experiencing Amenorrhea should consult a western doctor or other diagnostician in order to identify any obvious reasons for her lack of menses.
