Rosemary essential oil with cineole, sacred plant of the gods

In ancient Greece, rosemary branches were burned as an offering to the gods. In Athens as in Rome, rosemary was a sacred plant. The famous poet Horace (65-8 BC) also dedicated several verses to him.

A little history

Rosemary was an integral part of the recipe for “Vinegar of the Four Thieves”; a germicidal maceration used in particular to prevent the Great Plague , and was preserved for a long time in the form of a monograph in the Pharmacopoeia. It also entered into the formulation of the “Oppodeldoch” of Paracelsus to fight against all types of rheumatic pains , as well as gout .

Since the 16th century, “ Queen of Hungary Water ” (rosemary alcoholisate mixed with other medicinal plants) has been used as an “elixir of youth”. In 1378, aged 72, suffering from gout and paralysis, she received from a monastery the formula for this elixir, which miraculously restored her vitality, freshness and beauty… and subsequently married the King of Poland , despite his great age.
