There's evidence of systematic and effective medicine in Egypt a millennium before Hippocrates:
The research team from the KNH Centre for Biomedical Egyptology at The University of Manchester discovered the evidence in medical papyri written in 1,500BC...
"When we compared the ancient remedies against modern pharmaceutical protocols and standards, we found the prescriptions in the ancient documents not only compared with pharmaceutical preparations of today but that many of the remedies had therapeutic merit."
The medical documents, which were first discovered in the mid-19th century, showed that ancient Egyptian physicians treated wounds with honey, resins and metals known to be antimicrobial.
The team also discovered prescriptions for laxatives of castor oil and colocynth and bulk laxatives of figs and bran. Other references show that colic was treated with hyoscyamus, which is still used today, and that cumin and coriander were used as intestinal carminatives.
Further evidence showed that musculo-skeletal disorders were treated with rubefacients to stimulate blood flow and poultices to warm and soothe. They used celery and saffron for rheumatism, which are currently topics of pharmaceutical research, and pomegranate was used to eradicate tapeworms, a remedy that remained in clinical use until 50 years ago.
