NOW Foods Hyssop Essential Oil is a 100% pure, steam-distilled oil from Hyssopus officinalis, an aromatic Mediterranean herb with a complex, herbaceous, slightly sweet aroma that has been used in traditional European medicine and spiritual practices for thousands of years. In aromatherapy, hyssop is valued for its respiratory-supporting properties and its ability to promote mental clarity and a sense of purification. It is particularly useful in blends designed to support breathing comfort and clear, focused thinking during times of mental fatigue.
