Benefits of Centella asiatica
Brain Benefits
Centella asiatica may help protect the brain from damage due to toxic metal exposure, according to a study published in the December 2012 issue of the journal “Neurological Sciences.” In the animal study, daily doses of 150 or 300 milligrams per kilogram body weight for six weeks decreased oxidative stress — the damaging effects of toxins and cellular waste products — caused by aluminum. The herb also improved memory and decreased aluminum levels. Researchers concluded that Centella asiatica shows potential as a natural supplement for protecting against cognitive dysfunction and other forms of nerve damage from exposure to aluminum.
Cancer Prevention
A study published in the December 2012 issue of the “International Journal of Molecular Medicine” found that Centella asiatica may help protect against skin cancer caused by exposure to ultraviolet radiation. Treatment of human skin cells with Centella asiatica decreased the toxic effects of ultraviolet radiation by modulating the activity of certain genetic components of the cells.
Liver Health
Asiaticoside, an extract of Centella asiatica, may help prevent liver injury, according to an animal study published in the August 2010 issue of the journal “Phytomedicine.” Doses of 5, 10 or 20 milligrams per kilogram body weight of asiaticoside daily for three days reduced elevated liver enzymes in response to a liver-toxic chemical. Asiaticoside also decreased tissue destruction and significantly improved liver function.
Antianxiety
Centella asiatica decreased anxiety in laboratory animals in a study published in the September 2012 issue of the “Journal of Ethnopharmacology.” In the study, researchers observed significant improvements in several stress-induced behaviors in Centella asiatica-supplemented animals. The herb also improved body weight and levels of stress hormones. These preliminary results suggest that Centella asiatica may be a useful, natural means for managing chronic stress.
Wound Healing
Wound healing benefits of Centella asiatica extract were demonstrated in a study published in the October 2012 issue of the journal “Phytomedicine.” In the tissue culture study of human skin cells, asiaticoside increased migration and adhesion of new skin cells to the wound site. Asiaticoside also increased the numbers of skin-producing cells. Researchers note that asiaticoside may be useful as a component of artificial skin during wound healing.
