Etymology: In medieval or modern Latin: no Latin or Greek derivation is known.

Obsolete.

A term of Paracelsian Chemistry, used in various senses: e.g. ‘the quintessence of a thing; the reunion of different principles, as oil, salt, and spirit, by long digestion; the product of the detonation of nitre with another substance’ (Mayne Exp. Lex.). According to Rolfenkius, meaning ‘compound mineral spirits’. ( New Sydenham Soc. Lexicon)
