The diversity, purity and potency inherent to every NOW Pure & Natural Essential Oil has made them favorites among aromatherapists and casual users alike. Each one is highly concentrated, synthetic-free compounds and subject to the same testing as our Certified Organic oils. Each one of our pure oils is free of synthetics and is subjected to the same testing methods as our certified organic essential oils. Essential oils are highly concentrated extracts and should be used with care. They can be used at full strength for aromatherapy purposes, but for all other uses you should consult a book or other professional reference source for advice on uses other than aromatherapy. As with all NOW Solutions products, our pure essential oils are made with our industry-leading commitment to quality and are tested for potency, purity and identity to ensure you're getting a truly premium aromatherapy product. The benefits of aromatherapy are only realized with a truly pure essential oil, so be sure you're getting the most from your aromatherapy with pure aromatherapy oils from NOW Solutions.
