There are three main types of rosemary. The best one for aromatherapy use is the eucalyptol (cineol) chemotype, from Tunisia, Morocco & Italy. The camphor chemotype comes from Spain, & the verbenone chemotype comes from Algeria & Corsica. The latter is contra-indicated due to neuro-toxicity. Absolute Aromas supplies the finest top quality Tunisian Rosemary, which is the superior product. Rosemary is the classic "get up & go" oil. Try adding 3 drops of Rosemary, 2 drops of Lemon & 1 drop of Peppermint to a tepid bath before an important occasion. Adding a few drops to the final rinsing water for dark hair can help keep a natural shine. Do not use Rosemary during the first 4 months of pregnancy.
