It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that once a Jewish woman presented poisoned meat of a goat to the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) ate a morsel or so and immediately stopped eating, and the woman was summoned. He asked her, "Why did you do this?" She replied, "I intended that if you are truly a Prophet, Allah will inform you about it, and if you are not a Prophet, then people will be rid of you through me." The narrator says that whenever the Prophet (peace and blessings be upon him) felt the effects of this poison, he would have cupping done. That is why, once when the Prophet (peace and blessings be upon him) set out on a journey and put on Ihram, he felt some effects of it, so the Prophet (peace and blessings be upon him) had cupping done.
