Some benefits attributed to grapeseed oil include improving various cardiovascular conditions, helping lower high cholesterol and treating eye diseases associated with diabetes, according to WebMD. Grapeseed oil is also high in antioxidants, a well-known cancer-fighting agent.
The University of Maryland Medical Center lists among the many potential benefits of grapeseed oil its usefulness in treating heart disease and other cardiovascular complications. Grapeseed oil is believed to help with heart disease due to the antioxidants and flavonoids it contains, the same ones that exist in red wine, another substance known for its ability to benefit cardiovascular health.
WebMd also says that grapeseed oil may be beneficial to the cardiovascular system and is potentially effective in treating such conditions as varicose veins, diseases of the blood vessels, hardening of the arteries, hemorrhoids, high blood pressure, heart attack and stroke. Consumption of grapeseed oil may lower levels of bad cholesterol, relax restricted blood vessels, and reduce the overall risk of coronary heart disease.
Grapeseed oil is also known for its reported ability to reduce inflammation, making it especially effective in the treatment of edema, a type of swelling caused by irritation after surgery or an injury. Studies have shown that using grapeseed oil significantly reduces the amount of swelling present after such common medical events as breast surgery or a sports injury.
Other conditions for which grapeseed oil is said to be effective in treating include attention deficit-hyperactivity disorder, chronic fatigue syndrome, uterine bleeding and canker sores.
