Centella asiatica, a perennial herb also known as gotu kola, produces fan-shaped, green leaves that are harvested and used for medicinal purposes. Native to China, Japan, India and Indonesia, the herb has a long history of use in these areas. Medical practitioners in the United States and Europe have recently taken an interest in the herb for its possible health benefits. Although Centella asiatica appears safe when taken as directed, the University of Maryland Medical Center warns against taking the herb for longer than six weeks without consulting a doctor. Also, individuals with liver disease or a history of cancerous skin lesions should not take Centella asiatica. Always talk to your doctor before self-treating with this or any other herb, especially if you currently take prescription medications.

Centella contains pentacyclic triterpenoids, including asiaticoside, brahmoside, asiatic acid, and brahmic acid (madecassic acid). Other constituents include centellose, centelloside, and madecassoside.
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.
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.
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.
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 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.
Used for pain relief: take the Centella asiatica to dry and grind fine, 5~7.5g per day, take 3 times.

How Centella Asiatica Extract Fights Acne Inflammation
【Centella is an effective anti-ager】
Although some chemical components of Centella vary depending on where it comes from, Centella extract is generally high in skin-benefitting phytochemicals. It’s rich in vitamin C, vitamin A, vitamin B1 and B2, niacin, and carotene, which combine to brighten skin and fight premature aging.
Centella’s high antioxidant level is also noteworthy, and this combined with its ability to promote collagen production is what makes Centella a superstar anti-ager. Centella has a remarkable level of natural antioxidants, which is comparable to that of rosemary and sage. By the way, Centella leaf extract, as opposed to the extract from its stem and roots, is where you can find the highest level of antioxidants, which is why you commonly see Centella asiatica leaf water in the ingredient list.
A major component of skin aging is the decrease in the amount of type 1 collagen in the dermis, which is the layer between your epidermis and subcutaneous tissue. Asiaticoside found in Centella extract induces production of the type 1 collagen, which then helps your skin stay plump and youthful. Centella’s ability to boost collagen level also has proved the plant to be useful in treating cellulite.
【It’s an even better ingredient for acne-prone skin 】
When it comes to Centella’s skin benefits, you also can’t ignore its anti-inflammatory properties. Madecassic acid is one of the active compounds in Centella extract, and it’s known to play an important role in suppressing inflammation by inhibiting the release of pro-inflammatory cytokines and down-regulating the expression of certain enzymes that lead to inflammation. If your skin is acne-prone and you regularly deal with irritation and redness, make sure to look for Centella in the ingredient list.
Centella’s ability to fight inflammation is why K-beauty expert Joan Kim says it’s her go-to ingredient for fading acne. “Centella is a new ingredient that a lot of Korean brands are including in their products,” she told us during our interview with her back in March. “I noticed that all the products that work amazingly on my skin have Centella in it.” So if you’re looking for a natural ingredient that fights inflammation and scarring caused by acne, Centella is what you should look for.
