One sage, Abaye, said: anyone who has erectile dysfunction should take three 250 cc cups and add well-ground safflower boiled in water, and drink. A different sage, Rav Yochanan, testified that this medicine is effective and said that it gave him an erection like he had had in his youth.
The sages warned that there are three things a man can do which will make his body weak: eating while standing, drinking while standing, and having sexual relations while standing. The sages also warned that there are six things which a person does which lead to his immediate death: he returns tired from a trip, is bled, goes to the bath house, drinks wine and gets drunk, sleeps on the ground, and has sexual relations. One sage qualified this warning and said that immediate death only ensues if a person performs these all actions in order, one after the other. A different sage, Abaye, added: If one does these actions in order one immediately dies, but if he mixed up their order he does not die, his body only becomes weakened. The scholars asked: Was there not an incident with a woman, Orat, who forced her servant to do only three of those actions, and yet he died? Answer: His body was already weakened, so the three actions were enough to cause his death.
