| History | |||
| Gotu Kola has been used as a medicine in the Ayurvedic tradition of India for thousands of years. It is listed in the historic Susruta Samhita, an ancient Indian medical text. The herb is also used by the people of Java and other Indonesian islands. In China, gotu kola is one of the reported "miracle elixirs of life". This was attributed to a healer named LiChing Yun who, legends say, lived 256 years by taking a tea brewed from gotu kola and other herbs. Gotu Kola is prominently mentioned in the Shennong Herbal compiled in China over 2000 years ago. In the nineteenth century, Gotu Kola and its extracts were incorporated into the Indian pharmacopeia, wherein addition to being recommended for wound healing, it was recommended in the treatment of skin conditions such as leprosy, lupus, varicose ulcers, eczema, and psoriasis. It was also used to treat diarrhea, fever, amenorrhea, and diseases of the female genitourinary tract. Gotu Kola was first accepted as a drug in France in the 1880's. | |||

| Description | |||
|
Gotu Kola is a perennial plant native to India and other tropical countries. Its appearance changes, depending on growing conditions. In shallow water, the plant puts forth floating roots and the leaves rest on top of the water. In dry locations, it puts out numerous small roots and the leaves are small and thin. Typically, the constantly growing roots gives rise to reddish stolons. The leaves can reach a width of 1 inch and a length of 6 inches. Usually 3 to 6 red flowers arise in a sessile manner or on very short pedicels in auxiliary umbels. The fruit, formed throughout the growing season, is approximately 2 inches long with 7 to 9 ribs and a curved, strongly thickened pericarp. |
