Antioxidants are stable molecules that inhibit oxidation induced by free radicals.
Some foods are antioxidants producers such as fruits and vegetables and whole-grain, while others such as processed meats, alcohol are radicals producers. Particularly, fats and oils can easily be oxidized if they are cooked in high heat.

A free radical is a highly reactive atom with a single electron in the outer ring.
Free radicals produced in our body are a natural process derived either from essential metabolism through the processes of food intake or from external sources through directly contacting the skin or the air we breathe including exposure to X-rays, ozone, cigarette smoking, air pollutants, and industrial chemicals.
In order to counter the overexpression of free radicals which add to the body's burden. However, our body produces enzymes antioxidants and metal carrier proteins to neutralize them before they can cause damage.
Depending on the degrees of free radical invasion, antioxidant enzymes can be categorized into first, second, third and even fourth line of defense.

Oxidative stress has been found to induce widespread damage due to a set of a chain reaction auto-catalytically by free radicals that attacks the lipid bilayers of the cell walls, induces lipid, protein damage and alternation of cell DNA, leading to the onset of chronic diseases, including cancers.
On finding a natural ingredient for the prevention and treatment of diseases of oxidative stress, scientists compared the chemical profile that induces the antityrosinase and antioxidant activities of ethanol (EtOH) and methanol (MeOH) extracts of Sambucus nigra L. (Adoxaceae) flowers and leaves
Elder or Common Elder, is a shrub or small tree of the genus Sambucus of 30 species, belonging to the family Adoxaceae, native to the temperate-to-subtropical regions of both the Northern Hemisphere and the Southern Hemisphere.

The herb has been used in traditional and herbal medicine to treat constipation, colic, diarrhea, colds, flu, bronchial and upper-respiratory, irritation of the skin, rheumatism, etc.
Based on the results, researchers suggest, " ...the present investigation revealed the potential benefits of NF application in S. nigra extracts processing, suggesting the use of retentate fractions as a promising source for antioxidant and tyrosinase inhibitory compounds which could pave the way for future applications".
Taken altogether, Dandelion may be considered an antioxidative remedy for the treatment of diseases induced by oxidative stress, pending to the confirmation of the larger sample size and multicenter human study.
