sanskrit

During hemanta (early winter) the body is affected by excessive cold and as such is distressed, exposed to excessively cold wind, is too much roughed and dry, and with dosha adhered; on the other hand, the drugs administered for evacuation are hot by nature which become mild in potency due to exposure to excessively cold wind. Hence in conjunction of both these, the evacuative therapy becomes ineffective and the body is inflicted with the vatika complication. During summer season the body afflicted by excessive heat becomes distressed exposed to excessively hot winds too much lax and with excessively lignified dosha; the drugs, on the other hand, administered for evacuation being hot in nature become more intense because of exposure to heat; hence in conjunction of both these, the evacuative therapy produces effects in excess and the body also gets complication like thirst etc. During rainy season, when the sky is pervaded with cloud and water the sun, the moon and the stars are hidden and there are torrential rains. The earth is covered with mud and water; the body of living beings is moistened and the entire herbal wealth is damaged in nature, the evacuative measures become dull in action and the human bodies sluggish in recovery due to exposure to wind associated with moisture and clouds. Therefore, the measures like emesis etc. are stopped in the seasons ending with the rains (early winter, summer and rainy seasons) except in case of emergency. In emergency too, one should administer the therapy with great care after modifying the seasonal effects sufficiently by artificial means producing qualities contrary to the seasons and by making the measure appropriate in standard potency with variation in combination, processing and quantity.
