Coriander is an annual herb that grows three feet high and is very aromatic. Coriander seeds have been used internally for centuries. Coriander has a high linalool content, which helps skin maintain a healthy looking complexion. Coriander can be soothing when massaged into the body. Coriander’s sweet, herbaceous aroma is both relaxing and uplifting, making it a good rotation oil to use in blends to add a fresh, herbaceous note.
