Antioxidants are stable atom that plays a critical role in protecting the body against the attack of free radicals.
In other words, antioxidants inhibited the onset of free radical before they can cause a chain reaction in facilitating the protein, lipid and cell damage.
Antioxidants can either produced by the liver or intake from dietary sources. Under normal conditions, antioxidant enzymes produced by the body in a healthy individual are good enough to counter the bombardment of free radical attacks.
However, in people with a weakened immune system, intake dietary sources of antioxidants may be necessary.
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 ozone, cigarette smoking, air pollutants, and industrial chemicals.
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.
In order to counter the overexpression of free radicals which add to the body's burden, 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 is a condition caused by an imbalance of the ratio of free radicals and antioxidants in the body.
In other words, oxidative stress is either caused by overexpression of free radical or depletion of antioxidant enzymes in the body.
Cramp Bark is an ornamental plant, genus Viburnum, belongings to the family Adoxaceae, native to Europe and Asia. It has been used in traditional and herbal medicine as anti-spasmodic, anti-inflammatory, nervine. hypotensive agent and to treat menstrual cramps and pain, afterbirth, postpartum pains, excessive blood loss in periods, bleeding associated with the menopause, etc.
On finding a potential herbal medicine for the prevention and treatment of associated with oxidative stress diseases, researchers examined the antioxidant properties of fruit juices of six Viburnum opulus genotypes.
According to the antioxidant assays,
* V. opulus var. sargentii fruit juice demonstrated a remarkably stronger antioxidant activity, compared to others juice.
* Chlorogenic acid, the main phenolic compound in berry juices) depending on plant cultivar varied in the range of 0.54-6.93 mg/ml was found to be the dominant radical scavenger in V. opulus P3 (74%), compared to epicatechin and catechin (the main antioxidants in V. opulus var. sargentii) contributed to 40% and 23%, respectively.

More precisely, V. opulus var. sargentii followed by V. opulus P3 and V. opulus var. americanum possessed the highest antioxidant capacity.
Based on the findings, researchers said, "The obtained results may assist in selecting the most valuable V. opulus genotypes for the production of fruits possessing the strong antioxidant capacity and containing beneficial phenolic constituents".

Taken altogether, cramp bark(Viburnum opulus) depending on the types may be considered a functional herb for the prevention and treatment of diseases caused by oxidative stress, pending to the confirmation of the larger sample size and multicenter human study.
