Ayurveda has given prime importance to Mutravaha srotas (urinary system) and Srotogata Vikaras (urinary disorders). Being a system responsible for homeostasis of fluids in the body it also detoxifies the body by eliminating certain waste products through urine. When diseased, people produce symptoms such as, increased or decreased urine production, painful maturition, formation of stones, and thereby obstructed micturition, increased frequency of micturition, and so on. There are many herbs with varied actions specifically aimed at mitigating urinary system disorders. Drugs such as Jambu, Amrasthi, and the like, reduce the increased flow of urine, and hence, are considered as Mutrasangrahaneeya, whereas, drugs like Ikshu, Kustha, and so on, increase the flow of urine, and hence, are considered as Mutravirechaneeya. There are drugs like Padma, Utpala, and so on, which impart normal color to the urine and are known as Mutravirajaneeya dravyas. Asmarighna dravyas break down the calculi and remove them through the urine. These dravyas, when used under proper direction, help in relieving the pain and apathy caused by the disease.
