Gotu kola is an outstandingly important medicinal herb that is widely used in the Orient and is becoming increasingly popular in the West. Its Indian name is ‘Brahmi’ which means ‘bringing knowledge of the Supreme Reality’ and it has long been used there medicinally and as an aid to meditation. It is a useful tonic and cleansing herb for skin problems and digestive disorders. In India it is chiefly valued as a revitalizing herb that strengthens nervous function and memory.
The whole plant is alterative, cardio-depressant, hypotensive, weakly sedative and tonic. It is a rejuvenating diuretic herb that clears toxins, reduces inflammations and fevers, improves healing and immunity, improves the memory and has a balancing effect on the nervous system[147, 152, 238, 240]. It has been suggested that regular use of the herb can rejuvenate the nervous system and it therefore deserves attention as a possible cure for a wide range of nervous disorders including multiple sclerosis[K]. Recent research has shown that gotu kola reduces scarring, improves circulatory problems in the lower limbs and speeds the healing process. It is used internally in the treatment of wounds, chronic skin conditions (including leprosy), venereal diseases, malaria, varicose veins, ulcers, nervous disorders and senility[238, 240]. Caution should be observed since excess doses cause headaches and transient unconsciousness. Externally, the herb is applied to wounds, haemorrhoids and rheumatic joints.
The plant can be harvested at any time of the year and is used fresh or dried. Another report says that the dried herb quickly loses its medicinal properties and so is best used fresh.
