In Siddha medicine, tastes (Rasas) have specific physiological effects on the body and its secretions. The bitter taste (Tikta rasa) is recognized for its cleansing, detoxifying, and purifying properties. It is especially effective in purifying body fluids, including breast milk, by eliminating toxins and balancing excessive doshas. Therefore, bitter substances are traditionally recommended in certain postpartum therapies to cleanse and improve the quality of mother’s milk.
