It is narrated from Sayyidah Aishah (may Allah be pleased with her) that she said: My mother tried on me every method that is tried for women (to improve their health), but none of it had any effect on me. Then, when they wanted to send me to the Messenger of Allah (peace and blessings be upon him), they fed me cucumber and dates, and it had a very good effect on me.
