An animal study has revealed the antioxidant properties of hawthorn tree leaves and how they may be used to fight cataracts.

Hawthorn leaf extract was dropped into the eyes of rats with selenite-induced oxidative stress.  Researchers were able to measure significant increases in antioxidant levels in the eyes after the administration of the  drops.  According to study authors, “These results may be applied in the future for the prevention and treatment of cataracts.”

One of the leading causes of cataracts is the presence of free radicals.  The natural byproducts of metabolism,  these highly reactive chemicals cause oxidation, which in turn leads to the development of the opaque spot in the eye of a cataract.

Studies have shown beneficial effects of lipoic acid treatment on cataracts in rats. It may be of therapeutic use in preventing human cataracts and their associated complications. Lipoic acid has also been used to treat glaucoma.

Lipoic acid, also known as alpha-lipoic acid, is a sulfur-containing fatty acid. It is found inside every cell of the body, where it helps generate the energy that keeps us alive and functioning. Lipoic acid is a key part of the metabolic machinery that turns glucose (blood sugar) into energy for the body’s needs.

Lipoic acid is an antioxidant, which means that it neutralizes naturally occurring but harmful chemicals known as free radicals. Unlike other antioxidants, which work only in water or fatty tissues, lipoic acid is unusual in that it functions in both water and fat. By comparison, vitamin E works only in fat and vitamin C works only in water. This gives lipoic acid an unusually broad spectrum of antioxidant action.

In the July 28, 2009 issue of the journal Biochemistry, Italian researchers reported that the dipeptide carnosine can potentially treat and prevent cataracts.  Enrico Rizzarelli of the University of Catania and his colleagues tested the effects of D- and L-carnosine on bovine cultured alpha-crystallin, the major structural protein in the lens of the eye. This discovery further supports those of other researchers over the past decade, including that of Chinese researchers who, in 1999, discovered that carnosine has pronounced effect on primary senile cataracts (an effective rate of 100%) as well as mature senile cataracts (the effect rate was 80%).
