Kala is aniyathasidha nimitta karana, hence oushadha employed in a proper kala will result in expected karya, so our acharyas explain about the kshanadi and vyadhiavastha kala while administering medicine². Many functions of human body vary throughout day and night. Doshic variations exist in respect to end, middle and beginning of the age, day, night and digestion³. The advanced research in chrono-therapeutics also spread light into the above said concept to biological changes.
