Lavender essential oil has a light fresh aroma that is floral, light, with woody undertones. The most popular essential oil, it has a long list of applications dating back to antiquity- in fact, the word "lavender" comes from the Latin 'lavera,' meaning to wash. It is suitable for all skin types and is used to prevent scarring, stretch marks, and to slow the development of wrinkles. It is also known to moisturize dry scalp and hair. Aromatherapists use it to treat rheumatism, sprains, respiratory problems, abdominal cramps, depression, insomnia, tension-related problems, burns, sun-damaged skin, and various types of skin infections. It is particularly effective in treating headaches and migraines.
