Gotu Kola / Centella
Gotu kola has a long history of use, dating back to ancient Chinese and Ayurvedic medicine. Gotu kola is mentioned in the Shennong Herbal, compiled in China roughly 2000 years ago, and has been widely used medicinally since 1700 AD. Used in the ayurvedic tradition, Gotu Kola may stimulate nerve regeneration, according to researchers in the Department of Neurology at Oregon Health and Science University in Portland, Oregon. An extract of the herb caused measurable growth in a tissue culture of human nerve cells. In a laboratory animal portion of the study, doses of 300 mg per kilogram of body weight per day of gotu kola resulted in more rapid nerve regrowth and function recovery compared to a control group that did not receive the herb. The study appeared in the September 2005 issue of the “Journal of Pharmacy and Pharmacology.”
In addition to its neurological benefits, Gotu Kola has long been recommended for the treatment of scars and has been used as a topical cream in a comprehensive scar management programs. According to pharmacological studies, one outcome of gotu kola’s complex actions is a balanced effect on cells and tissues participating in the process of healing, particularly connective tissues. One of its constituents, asiaticoside, works to stimulate the regeneration of skin cells and underlying connective tissue. In a study published in Annals of Plastic Surgery, gotu kola accelerates healing of burns and minimizes scarring. Observationally, it was found to improve scar maturity from an average of six months without treatment to three months with treatment.
