नारीणामप्रजातानांनराणांचाप्यपत्यदाः। उभयार्थकरादृष्टाःस्नेहबस्तिनिरूहयोः॥२२॥
Both, sneha and niruha basti (medicated enema with and without oil) give ishta (desired) results. These yapana bastis serve both the purposes i.e. snehana (oleation) and shodhana (elimination of vitiated doshas) from the body.
