Any longevity claims for gotu kola as farfetched as the tale of Li Ching Yu. But modern science has found support for other traditional claims for this ancient herb.
1. Wound Healing. Gotu kola may spur wound healing. It accelerates healing of burns and minimizes scarring.
2. Psoriasis. Supporting its traditional use for skin diseases, it showed that a gotu kola cream can help relieve the painful scaly red welts of psoriasis. Seven psoriasis sufferers used the cream. It healed the welts in five within two months, and only one of the five experienced any recurrence within four months after the treatment ended. Gotu kola cream is not available commercially, but you can use a compress of gotu kola infusion to help treat psoriasis.
3. Leprosy. Gotu kola’s traditional use in treating leprosy (now called Hansen’s disease) was supported by a study published in Britain. The bacteria that cause leprosy have a waxy coating, which protects them against attack by the immune system. Gotu kola contains a chemical (asiaticoside) that dissolves this waxy coating, allowing the immune system to destroy the bacteria.
4. Leg Circulation. Gotu kola also may help promote blood circulation in the lower limbs, those with venous insufficiency.
5. Intriguing Possibility. Poor circulation through the legs causes varicose veins. Gotu kola has not been studied specifically as a treatment of this condition, but it’s possible ability to improve leg circulation might help prevent and treat varicosities.
Rx for Gotu Kola
Use an infusion of gotu kola to help improve circulation in the legs. Or give it a try if you have insomnia. For an infusion, use ½ teaspoon per cup of boiling water. Drink up to 2 cups a day. Gotu kola tastes bitter and astringent; adding sugar, honey, and lemon, or mixing it into an herbal beverage blend will improve its flavor.
The only confirmed side effect in humans is skin rash in sensitive individuals.
The FDA considers gotu kola an herb of “undefined safety.” For otherwise healthy non-pregnant, non-nursing adults who have no history of cancer and are not taking other tranquilizers or sedatives, gotu kola is considered relatively safe in amounts typically recommended.
