Description
Oregano Essential Oil is steam-distilled from the leaves of Origanum vulgare, a robust perennial herb from Europe and Asia. With a potent, herbaceous scent, it is recognized for its antimicrobial and immune-supportive properties. It pairs well with thyme, rosemary, and spice oils, making it a powerful addition to aromatherapy blends and herbal preparations. Used sparingly in personal care, it enhances cleansing formulations. Its strong nature makes it a trusted component in holistic remedies and wellness applications.
