Gotu kola (Centella asiatica) is a frontline medicine in most herbal traditions. In Ayurveda, it’s called “brahmi,”which means “godlike,” a reference to its prodigious benefits. It strengthens memory, concentration, and intelligence; promotes longevity; and improves the voice, physical strength, and complexion. A 2020 scientific review pointed out its use in neurological, endocrine, skin, cardiovascular, gastrointestinal, immune, and gynecological diseases, and mentioned anti-inflammatory, antioxidative stress effects.
Gotu kola strengthens memory, concentration, and intelligence, and stabilizes mood. A 2017 scientific assessment found that it also increases alertness and reduces anger. Recently, a Korean study concluded that components in gotu kola show potential for treating Alzheimer’s disease, a very promising direction. Follow-up animal research from India used gotu kola tea to improve cognitive behavior in two different laboratory models of Alzheimer’s disease. A thorough 2020 study in the journal Brain Science described gotu kola as having extensive promise in this area, and another study reported that gotu kola constituents reversed cognitive deficits in an Alzheimer’s model.

Gotu kola is used in the repair of nerve tissues from crushing trauma, such as spinal injury and neuromuscular disorders. The herb has shown potential in enhancing neuroregeneration, including the regeneration of crushed sciatic nerves and protection from neuronal injury in hypoxia conditions. A recent discovery from Oregon Health and Science University validated gotu kola’s use for treating diabetic neuropathy, and in 2020, scientists reported that gotu kola helped regenerate a peripheral nerve.
