Grapeseed oil has been used in home remedies and medicinal purposes for centuries. Grapeseed oil contains polyphenols, flavonoids, vitamin E, linoleic acid (an essential fatty acid), and oligomeric proanthocyanidin. It’s an efficient skin moisturizer, repairs damaged hair, can be used as a massage oil, and works well to treat sunburns or as a sunblock. Filtered grapeseed oil offers anti-inflammatory, antimicrobieal and adaptogenic properties, and can be used in the treatment of issues including edema, dry skin, dermatitis, acne, arthritis, bruises, PMS, weight loss, hair loss, and cardiovascular diseases. Some studies suggest that consuming grapeseed oil regularly may reduce the development of certain types of cancers, and help with liver damage caused by chemotherapy medication.
