In the 4th century AD, while visiting a doctor, Hippok accidentally discovered that olive oil was used by the wounded to smear wounds. This behavior aroused Hippok's great curiosity-does olive oil have special therapeutic effects? Since then, Hippok has started a long research on the medical use of olive oil. In the course of research, Hippok gradually summed up more than 60 different diseases that can be treated by olive oil, including skin trauma and burns, ear infections and many other problems. Hippok also became the first scholar to systematically expound the benefits of olive oil to human health. Under its influence, olive oil is no longer only used in the religious field, but gradually becomes an indispensable article for people's cooking, medical treatment and beauty.
