Anciently, it was used to treat leprosy, calm the nerves, increase mental and physical power, to stimulate and rejuvenate the brain, to prevent nervous disorders, mental fatigue and senility.
Gotu kola is considered to be one of the best herbal tonics. A tonic is a substance that works to put the body into balance or normality. To be in balance means to work properly and to be in a healthy state.
An herbal tonic helps to promote an optimum state in the body systems. Gotu kola helps to gradually build the nervous system as a nervous system tonic. It has been used for many different ailments including nervous disorders, deficient mental function, memory problems, epilepsy and schizophrenia.
It works by cleansing and purifying the blood by neutralizing acids and helps the body defend itself against toxins.

Research done in India found the water extract of fresh leaves to help improve memory and learning. It was also found to help improve and overcome the negative effects associated with stress and fatigue.
Other clinical trials in India have found that gotu kola can help increase the I.Q. and mental ability of mentally retarded children. The children involved in the study showed improved mental capacity as well as improved behavior.

Researchers in Madagascar began the modern studies on gotu kola in 1949.
An extract was injected into the leprosy patients directly on nodules and ulcerated areas. The extract was found to aid in dissolving the covering to promote eventual healing in the subjects. This opened the door to the use of gotu kola for healing skin ailments. 255 There have also been excellent results from studies done in treating burn patients with second and third degree burns due to boiling water, electrical rent, or gas explosions. The gotu kola extract helped limit the swelling and shrinking of skin which is a result of burning. It reduced infections and scarring and increased healing time.
Gotu kola contains two saponin glycosides known as brahmoside and brahminoside which are known to promote relaxation. A study done on animals showed large doses caused a sedative action.
