abnormal menstrual flows as per ayurveda

Ayurvedic texts define normal menstruation [2] as one which is not associated with pain or burning sensation, excreted blood is not unctuous, not very scanty or excessive in amount, and the color of the blood resembles the red juice of lac, rabbit’s blood. This normal menstruation occurs when the three Doshas exist in a proper balanced state and any imbalance in them will cause abnormal menstruation.

A Vatika menstrual flow, for example, will be accompanied by pain. This is so because, the presence of Vata in excess, will result in its Sheetha and Khara qualities to cause constriction of blood vessels, which in turn will result in very less menstrual discharge and will also obstruct the free flow of Vata, thus causing pain. On the other hand, a Paittika menstrual flow will result in heavy bleeding and the Pitta Dosha will cause swollen breasts, acne, etc.  Kapha Dosha is by nature dull, heavy and sticky and hence a Khaphaja menstrual flow will cause heavier flow with clots in the menstrual blood. It is to be noted that all these external symptoms of pain, scanty flow, excess flow, etc. are considered signs of abnormal flow.
