The assertion states that according to Charaka, Shirovirechana is contraindicated in a person who has just undergone Sneha
-pana. This statement is true because after undergoing Sneha
-pana, the body is already lubricated, and subjecting the body to Shirovirechana (which is a procedure involving purging) may not be suitable and could lead to excess imbalances.
However, the reason given is incorrect. While Shirovirechana could indeed aggravate conditions like Kasa (cough), Shvasa (dyspnoea), and Pratishayaya (congestion), this is not the primary reason for its contraindication after Sneha
-pana. The contraindication is more about the imbalance caused by subjecting the body to further cleansing procedures after the lubrication.
Thus, while assertion (A) is true, the reason (R) provided is not the correct explanation for the assertion.
