Gotu kola (Asian pennywort) for memory and concentration
Gotu kola gained the most popularity as a dietary supplement for memory and concentration, which has scientific justification.
As scientists have shown, Gotu kola activates the release of neurotrophic factor of brain (BDNF) – a protein that stimulates the formation of new brain cells.
In addition, Gotu kola contributes to the development of dendrite (this is the element of the neuron, the structure transmitting signals received from other neurons by the synapses to the body of which it’s part), thereby increasing brain plasticity and communication between brain cells.
Gotu kola also contributes to the stimulation of nerve growth factor (NGF) and protects the brain against the harmful effects of free radicals and neurotoxins
Gotu kola (Asiatic pennywort) for calming and depression
Indian researchers from the Institute of History of Medicine and Medical Research in New Delhi have shown that water extract from the Gotu kola reduces spontaneous activity in mice and prolongs sleep time. All thanks to two glycosides called the Bramosid and Braharnozide. The calming effect of these substances corresponds to the action of a mild sedative from the pharmacy shelf. Studies comparing the action on mice with an aqueous extract of dipper and diazepam (a psychotropic drug from the benzodiazepine group) have shown that aqueous extract reduces spontaneous activity to the same extent as diazepam. The extract also reduced convulsions caused in mice. In addition, the anxiolytic effect in mice was milder than after benzodiazepine.
Gotu kola (Asian pennywort) for stomach ulcers
Chinese scientists from The University of Hong Kong showed that the water extract from the Asian pennywort, as well as its main ingredient, Asiaticoside, accelerated the healing of stomach ulcers. Administration of the extract to rats resulted in a reduction in the size of the ulcer within 3 to 7 days, depending on the dose administered. In other studies, stomach ulcers were induced in mice. It was observed that subcutaneous administration of Asiaticoside for 3 hours before induction of ulcers significantly reduced their formation.
