In 1983, OSA began as a company exclusively dedicated to aromatherapy and the beauty and superiority of truly unadulterated authentic essential oils. Then, as now, we believe paying a little more for a smaller quantity of an authentic oil is a much better deal than buying cheap or cleverly diluted product. We have only on objective:

Offer genuine and authentic essential oils.

We maintain that knowing the producer is the best safeguard against adulteration. We also analyze our essential oils by GC/MS, but we know that analysis alone has not kept adulterated oils out of aromatherapy. To the contrary, analysis hype is often used to sell cleverly adulterated oils and justify homogenization. We use analysis to discover the variations arising from growing regions and to confirm the fingerprint of our trusted distillers.
