What is Pomegranate Seed Oil?
Pomegranate seed oil is a powerful and fragrant natural oil that is cold pressed from the seeds of the pomegranate fruit. Bearing the scientific name Punica granatum, pomegranate seeds and fruit are widely considered some of the healthiest fruit-based substances, due to their high concentrations of nutrients and antioxidants. The seeds of a pomegranate, also known as arils, are what people eat in this fruit and the cold-pressing of these seeds is done to acquire the potent oil. You will find pomegranate seed oil in many different cosmetic products, such as shampoos, soaps, moisturizers, and skin salves, but this oil is also used in aromatherapy and diffusers. This oil is extremely concentrated, so only a very small amount is required for the effects to be felt. The oil is not only on the expensive side, but can also cause allergic reactions, so culinary use is not common. However, internal consumption is considered safe in very cautious moderation. The many benefits of the oil come from its high levels of punicic acid, vitamin C, flavonoids, linoleic acid, and oleic acid, among various other active components.
