There are Two stones sizing upto 5mm in my left

Sat Nam,

Yoga can help you improve your kidney function. However, if you already have stones, you should consult a doctor, or a herbalist…I heard there are some herbs excellent to disolve kidney stones.

These exercises will help your kidneys to function better.
