khasapalaṃ śuṇṭhīkvāthaḥ ṣoḍaśāṃśena guḍena niśi pītaḥ /
kurute ratau na puṃso retaḥ patanaṃ vināmlena //

One pala of poppy [capsules], a decoction of dry ginger, and a sixteenth part of jaggery, drunk at night, / prevents the emission of semen for a man during intercourse, unless he takes sour food.
