Estrogens also regulate GAGs in the skin, and losing these hormones results in dehydrated, itchy skin. Estrogenic loss also reduces the number of blood vessels in the skin, resulting in pale skin with a lack of nutrients traveling to the skinâs surface.2 In all, we get pale, thin and dry skin.
Joseph Black recognized magnesium as an element in 1755. It was isolated by Sir Humphry Davy (1778-1829) in 1808 almost 200 years after its discovery. He electrolysised mixture of magnesia (magnesium oxide, MgO) and mercuric oxide (HgO). Davy's first suggestion for a name was magnium but the name magnesium is now used.
In 1618 a farmer at Epsom in England attempted to give his cows water from a well. This they refused to drink because of the water's bitter taste. However the farmer noticed that the water seemed to heal scratches and rashes. The fame of Epsom salts spread. Eventually they were recognised to be magnesium sulphate, MgSO 4.
