Perilla oil, derived from the steam distillation of perilla plant leaves, is an essential oil characterized by a high perillaldehyde content (≥55%), giving it a distinctive minty, herbaceous aroma. It is primarily used in the fragrance and flavor industries to impart fresh, herbal notes in perfumes, cosmetics, soaps, and food flavorings. In aromatherapy, perilla oil is employed for its calming, uplifting, and stress-relieving properties. The oil also demonstrates antimicrobial, antioxidant, and anti-inflammatory effects, making it valuable in natural skincare products, natural preservatives, and pharmaceutical formulations for skin health and minor irritations. Its light yellow to yellow oily liquid appearance and refractive index (1.4985-1.512) confirm its purity and suitability for specialty applications.
