Gotu Kola (Centella asiatica) is well known to the natives of Madagascar, India and Sri Lanka. It is also found in North Australia, China, Indonesia, Iran, Malaysia, New Guinea, and other parts of tropical and sub tropical regions of the world. It is an easily grown plant and creeps over land vigorously. Just spread the seeds and they will come out and cover the soil. It spreads fast and has stolon type of stem. Its leaves are reniform and well raised on their petioles. It is a member of the umbelliferae family of the class magniolopsida and division anthophyta. Carrot, parsley and coriander are closely related and belong to the same family. Gotu Kola is also known as Indian pennywort, marsh penny, water pennywort and hydrocotyle - just a few names out of many.
Gotu Kola has been known to treat a variety of human ailments right from skin problems, circulation of blood, nerve soothing to memory enhancement. It has been clinically proven to raise mental concentration and comprehension. It stabilizes the central nervous system. Its antibacterial, antiviral and anti inflammatory properties are well known. The leaves and stem of this herb contribute to these medical benefits. By observing elephants feeding on the herb, people in the ancient past came to the conclusion that gotu kola adds to longevity. Gotu Kola does have the reputation of being a longevity promoter. A popular Sinhalese saying is “Two leaves a day keeps old age away”. Gotu Kola may not add years to your life, but it could stimulate the immune system, accelerate wound healing, help treat psoriasis and improve circulation of blood in the legs which in turn helps prevent varicose veins. In the olden days, many health practitioners were aware of gotu kola's benefits for leprosy. According to one report “in 1852 Dr. Boileau of India, being infected for many years with leprosy, experimented with this herb and recovered”.
In China a story goes that master herbalist Li Cheng Yun lived to be 256 years due to his usage of traditional Chinese herbs including gotu kola. In Sri Lanka, a popular folklore tale speaks of a prominent king from the 10th century named Aruna who claimed that gotu kola provided him with energy and stamina to satisfy 50 women in his harem. So that is how many fantasies go for medical wonders of gotu kola.
Naturopathic physicians suggest use of this herb, along with foods high in vitamin c, for treatment of burns. There is some evidence that combinations of vitamins and 3 compounds in gotu kola – asiatic acid, asiaticoside and madecassic acid stimulate collagen synthesis, a key element in skin repair (Collagen is a protein that forms the basic structure of skin). Gotu kola stimulates the regeneration of skin cells and underlying connective tissue. In clinical trials, it has been proven useful in treating eczema, wounds and other skin conditions. Recent researches also suggest that one compound (asiaticoside) in gotu kola is among the most prominent treatment for leprosy.
Latest studies also show benefits of gotu kola extract in venous insufficiency (lower limbs), water retention in ankles, foot swelling and varicose veins. It also strengthens veins and capillaries. It is particularly effective for patients who are inactive and confined to bed. These active compounds in gotu kola work together in giving relief to all the ailments mentioned above.
Gotu kola is available in capsules, cut and sifted, as well as in powder form. Use it as you wish. This can be added to juices, other beverages and to salads as well. In India, it is used in a popular cold drink during the summer called “thandai”. I would suggest using it in soups as well. Make sure you are not allergic to the herb, use the herb in moderate amounts or as recommended.
Always discuss these treatments with your own physician. He or she knows the best about your health. Take care of your health with knowledge and enjoy the winter season until it lasts.
My next article will be posted in the first week of March on another interesting herb. Till then take care of yourself and keep warm!
