Oxidative stress is a medical condition characterized by the imbalance of the ratio of free radicals and antioxidant enzymes produced by the host tissue.
In some cases, this reaction also is caused long-term accumulation of toxic substances in the body, such as lead, cadmium, mercury, and arsenic.
Sadly, a prolonged period of oxidative stress presented in the human body can cause oxidative damage to biomolecules, (lipids, proteins, DNA) and the death of healthy cells through cytotoxicity.
More precisely, exogenous factors, such as cigarette smoke, and endogenous factors, such as the oxidative burst from activated macrophages are some of the factors involved in the risk of oxidative stress.
The Liver Pathophysiology, 2017 in the explanation of the cause of oxidative stress, wrote, " (1) the presence of xenobiotics, (2) the activation of the immune system in response to invading microorganisms (inflammation), and (3) radiation, which makes oxidative stress a common denominator of toxicity or stress".
In other words, oxidative stress may be preventable by following a diet rich in antioxidants such as a diet with higher fruits and vegetable consumption accompanied by moderate exercise and reducing intake of saturated and trans fat and processed foods.
Eyebright is one of the species of flowering plants, genus Euphrasia, belonging to the family Orobanchaceae, native to Europe.
* The eye drops exerted a strong antioxidant activity by decreasing ROS levels and protein and lipid oxidative damage.
Based on the results, researchers suggest, "...an eye drop containing Matricaria chamomilla and Euphrasia officinalis extracts exerts positive effects against UVB induced oxidative stress and inflammation and may be useful in protecting corneal epithelial cells from UVB exposure".
