We all know taking a dip in the sea is very good for you; ocean water differs from river water in that it has significantly higher amounts of minerals, including sodium, chloride, sulphate, magnesium and calcium. This is why it’s highly useful for skin conditions such as psoriasis, but did you know humans have been using sea water for medicinal puroses since at least ancient greek times?

Plato said, “The sea cures all ailments of man.”  Euripides said, “The sea washes away all men’s illnesses.”  Plato, Hippocrates and Aristotle recommended hot seawater baths.  Cato the Elder served his slaves a mixture of wine and seawater to restore their energy. Animals on Earth originally evolved in the sea, making it our biological “home”. Chemically, it is spookily similar to our own blood plasma.

I don’t much fancy drinking it, but Rene Quinton, a French biologist, recognised the benefits of purified sea water which he called “Quniton Plasma” and admistered it to 100s of children and adults in the early part of the 20th century, curing cholera, athrepsia, dyspepsia, rheumatism, psoriasis, alopecia, colitis and many other ailments. Today, you can still experience sea-water therapies under the banner of “Thalassotherapy”, which I noticed a lot of whilst in Barcelona. Oh, and back in England don’t forget to check out Newcastle’s Ocean Baths.
