Health Benefits of Gotu Kola
Science has shown that there are several active ingredients behind gotu kola's properties. These are some of the main benefits of gotu kola:
Enhancing memory. The neuroprotective properties of gotu kola has shown to improve cognitive function in people with Alzheimer's disease and various age-related diseases.

How It Works
Gotu kola possesses triterpenoid compounds (mainly asiaticoside), which are responsible for improving age-related cognitive deficits by stimulating vascular activity in the brain.1,2 They also play a key role in its wound healing effects by stimulating collagen production.3
Goty kola's content also includes high levels of carotenoids as well as polyphenols, mainly flavonoids, volatile oils, and tannins, all of which are credited for the regenerative, anti-aging properties of this herb.
Another reason for gotu kola's varied medicinal properties is its high nutritional value. The herb contains large amounts of vital nutrients, including B-group vitamins and vitamin C (ascorbic acid), calcium, iron, serine, lysine, magnesium, and glutamate.

Aloe and jojoba also speed up wound healing, whereas ginkgo and rosemary increase blood circulation.
