A woman of the household of Zuhayr (may Allah have mercy on him) said: I had pain in my throat, so I came to Sayyidah Mulaykah bint Amr al-Zaydiyyah (may Allah be pleased with her), who was from the descendants of Zaydullah bin Sa'd. She put out cow's ghee for me and said: the Messenger of Allah (peace and blessings be upon him) said: "Its milk is a cure, its ghee is a remedy, and its meat is a disease."
