As-Suyuti, in “Medicine of the Prophet” [pbuh] said, “The medical authorities agree that whenever an illness could be fought with nourishment and diet, then medicine should be avoided. In addition, they agree that whenever it is possible to use only one substance or ingredient as a remedy, a compound remedy should not be used. They agree that the body will be harmed if doctors over prescribe medicine. This is because the remedy might not find an illness to cure, or might find an illness that it cannot cure, or might be suitable for the illness, but an excess dose may be given, thereby compromising the health of the body.”
