This is a common question. While both oils are derived from the same plant, their uses are slightly different: Rosemary extract oil is often diluted and used in cosmetics or food products. Pure rosemary essential oil is highly concentrated and used for therapeutic benefits like hair growth, skincare, and aromatherapy. TruVeda offers both, but if you’re looking for real health and beauty benefits, our organic rosemary essential oil is your best choice. It’s versatile, potent, and 100% natural.
