What are the medicinal properties of olive oil.?can it help to improve the skin and take care of skin disorder

I don't know what skin disorder you are referring to, that is a broad question. The skin improving properties of olive oil is that it had a moderate supply of essential fatty acids that are necessary for skin health. It makes for a good natural moisturizer by putting a few drops in your hand and applying to damp skin, ie. legs and face etc. DL
