SOURCE OF THE MENSES.
From whence comes the menstrual discharge? This has been a question which has caused a good deal of dispute on the part of some.
The majority of writers, of all ages, agree in regarding the menstrual flow as coming from the womb; yet some have held that it issues only from the vagina and more external parts. This latter supposition cannot hold good except, possibly, now and then, as an exception to the general rule. Blood may exude from any part of the body, from the vagina and external organs of generation, as well as from the womb. But this organ, beyond doubt, is the great and principal source of the menstrual discharge.
