The lapis lazuli is a metamorphic rock. Its use is very old, tonic at 7.000 years. The name derives from Latin lapis lazuli, who mean stone, and from Persian, لاژورد lajevard, which means blue.
During the Roman epoch, lapis lazuli had the reputation to be an aphrodisiac.
With the Middle Ages, other medicinal virtues were allotted to it: good for the robustness of the members, and preventing the spirit of the fear, the doubt and the desire.
It was drunk crushed, mixed with milk.
