Alkahest (or alcahest) is a hypothetical universal solvent, having the power to dissolve every other substance, including gold. It was much sought after by alchemists for what they thought would be its invaluable medicinal qualities. The name is believed to have been invented by Paracelsus (1493–1541) from Switzerland, who modelled it on similar words taken from Arabic, such as ‘alkali’. Paracelsus' own recipe was based on caustic lime, alcohol, and carbonate of potash. He believed that this element alkahest was, in fact, the philosopher's stone.
In modern times, water is sometimes called the universal solvent as well, because it can dissolve more substances than any other known solvent, due to its chemical polarity.
