How Herbs Could Affect Eye Health

Please pass the rosemary!

An Investigative Ophthalmology & Visual Science journal study revealed that carnosic acid, found in the herb rosemary, is good for your eyes.

Dr. Stuart A. Lipton and his team discovered that the herb component could help fight eye diseases that affect the outer retina, including age-related macular degeneration and light-induced retinal damages.


According to a ScienceDaily article about the study: 

The researchers exposed (retinal) cells growing in the dish to hydrogen peroxide in order to induce oxidative stress, a factor thought to contribute to disease progression in eye conditions such as macular degeneration and retinitis pigmentosa. They found that cells treated with carnosic acid triggered antioxidant enzyme production in the cells, which in turn lowered levels of reactive oxygen and nitrogen species (cell-damaging free radicals and peroxides).

Dr. Lipton's lab team will now work on developing derivatives of the acid that prove more effective in protecting the retina and putting them to the test.
