Scientists in France say they have recreated the perfume of the pharaohs which they believe was used by the ancient Egyptians to boost their love-lives. But as the ingredients of Kyphi perfume, said to be an aphrodisiac which helps wearers relax, includes cannabis, it cannot be commercially produced. Experts from L’Oreal and C2RMF, the Centre for Research and Restoration of French Museums, succeeded in recreating the legendary Kyphi perfume. French researcher Sandrine Videault, who for years had attempted to recreate the aroma, was finally able to do so with the help of Greek historiographer Plutarch. The Greek writer had written that "Kyphi had the power to send someone to sleep, to help them have sweet dreams, to relax them, to drive away the worries of the day and to bring peace." But Videault said: "Kyphi will never be sold because some of the ingredients are illegal substances. In any case the smell is probably much too pungent for the modern world."
