Doctors Health Press, a division of Lombardi Publishing Corporation, and publisher of various natural health newsletters, books, and reports, including the popular online Doctors Health Press e-Bulletin, is reporting on a new study that indicates that the herb rosemary could be an effective preventive for macular degeneration.
As Doctors Health Press e-Bulletin (http://www.doctorshealthpress.com/food-and-nutrition-articles/this-herb-can-help-save-your-sight) notes, macular degeneration is the most common vision problem among older adults, and is also the leading cause of blindness in North America. While macular degeneration has many suspected causes, studies have shown that antioxidant compounds could protect against it.
As the article “This Herb Can Help Save Your Sight” reports, this new study—conducted at the Sanford-Burnham Medical Research Institute in California—found that “carnosic acid,” which is a component of rosemary, promotes overall eye health. In particular, it protects retinas from degeneration and toxicity, which are related to macular degeneration. The Sanford-Burnham researchers earlier found that carnosic acid acts as an antioxidant in the brain.
The Doctors Health Press e-Bulletin article states that in the new study, researchers tested carnosic acid on cells from the retina exposed to hydrogen peroxide, which would trigger oxidative stress. Not surprisingly, the cells treated with carnosic acid had antioxidant enzyme production, which indicates cell protection.
The article adds that researchers also tested rosemary’s core ingredient in an animal model, where eyes were exposed to light-induced damage. Those rodents pre-treated with carnosic acid had a thicker outer nuclear layer in the eye, indicating that their photoreceptors were protected; they had a measurably better photoreceptor function after the test.
As the Doctors Health Press e-Bulletin article concludes, while pharmaceutical firms are developing different types of synthetic carnosic acid and related compounds to protect the retina and related tissues from degenerative conditions, there are natural alternatives, like rosemary, already available. It adds that rosemary has also been shown to have other healthy properties, including the ability to protect against memory loss.
