Overview
Lavender is one of the most beloved and versatile medicinal herbs, renowned worldwide for its exquisite fragrance and remarkable therapeutic properties. Native to the Mediterranean region, lavender has been used for over 2,500 years for its calming, antiseptic, and analgesic effects. Its essential oil is among the most studied in aromatherapy, with clinical evidence supporting its use for anxiety, insomnia, pain, and skin conditions.
Traditional Use
Lavender has been used since ancient times. The Romans added lavender to their baths (the name comes from the Latin "lavare" — to wash) and used it as a perfume and insect repellent. Ancient Egyptians used lavender in mummification and perfumery. In medieval Europe, lavender was strewn on floors to freshen air and repel insects. Traditional herbalists used lavender for headaches, anxiety, insomnia, and as an antiseptic for wounds. During World War I, lavender oil was used to disinfect wounds when conventional antiseptics ran out.
