Folk History and Use:
Historical use is mentioned in the Chinese Shennong Herbal (circa 1st-2nd century CE). Chinese herbalist, Li Ching-Yun, regularly used Gotu kola and was believed to have lived until he was 197 years old. The herb was therefore called “miracle elixirs of life”. It was used as an aphrodisiac and for treating abscesses, asthma, diarrhea, epilepsy, fever, hepatitis, high blood pressure, mental fatigue, stomach ulcers, and syphilis.
Common use today includes treatment of chronic venous insufficiency, burn wounds, stress-related duodenal ulcers, toning stomach, scleroderma, psoriatic arthritis, and scabies.
In Ayurvedic medicine, Gotu kola is used as a tonic to reduce mental fatigue and improve mental clarity. It is also used for internal and external ulcers, blood circulation, and reducing edema. Treatment listed in the Ayurvedic Pharmacopoeia includes inflammation, tastelessness, fever, cough, itching, skin diseases, excessive urination, dyspnea/asthma, and anemia. Brahma Rasayana is a mixture of herbs and fruits taken with warm milk as a cerebral tonic.
TCM uses Gotu kola for treating jaundice, heat-stroke with diarrhea, urolithiasis in the kidney, bladder, or urethra, hematuria, carbuncles, boils, and traumatic injuries.
Gotu Kola can absorb heavy metals from contaminated soils. ⁶
