In nature, function determines the form. Consequently, the form of the brain is determined by its functions. It should not be a surprise then that one of the most precious herbal medicines in Ayurvedic Medicine and Chinese Medicine, Gotu Kola (Sanskrit: Brahmi, Latin: Centella asiatica), has leaves that looks very much like the human brain. After all, it has been revered for thousands of years for its ability to enhance cognitive function. This plant is a true panacea of healing; a true adaptogen (a term used to describe plants that have a balancing and harmonizing effect on the mind, body and spirit). For this reason, it has been highly appreciated both in India and in China, with references to plants appearing in Ayurvedic medical texts and classical texts.
1. Improving brain function and longevity
In all Asia, Gotu Kola was known as the longevity plant. Daoist Master and Plant Seed Grower, Li Ching-Yuen was, during his time, a famous promoter and user of the plant. Ancient Chinese medical texts say he died at the age of 256 and attributed his longevity mostly to the daily use of Gotu Kola. While the accuracy of these records can be debated, Gotu Kola is a well-studied plant, and the vast majority of its therapeutic properties, including the ability to extend lifetime, have been documented and validated by science and the scientific community.  Its life extension properties are most likely due to a synergistic combination of its powerful effects on the mind, body and spirit – in every sense, on the whole person. The benefits of the plant range from, to significantly improve memory, restore brain cells and nerve function ,improves blood quality and circulation, restores digestion and accelerate wound healing.

2. Increasing intelligence and cognitive function
Of particular interest in our modern world, with rapid intellectual rhythm, it is the ability of Gotu Kola to enhance almost every aspect of mental functioning [1-13]. Usually, plants or substances that can produce such effects are very stimulating; however, Gotu Kola is a modulator, which makes it ideal for anyone looking for cognitive stimulus without the undesirable and unbalanced side effects of the stimulant substances. In a study, children who took half a gram of Gotu Kola extract powder each day for one year showed a significant improvement in their intellectual level. After six months, there was a substantial improvement in intelligence, cognitive function and concentration. 
3. Rebuilds the nervous system and reduces anxiety and stress
In Ayurvedic Medicine, Gotu Kola effects classifies as a Rasayana or rejuvenate plant because of its ability to restore the balance and health in many parts of the mind and body. For example, it is an extremely healing plant for the nervous system and has been shown to repair and restore axons , which are used to transmit nerve impulses to the brain and body. As such, it has been used as an anti-anxiety, anti-stress and anti-insomnia medication throughout its long history of use. [6.12]
Gotu Kola’s ability is to improve blood quality and circulation  is probably one of the main components of its rejuvenating effects, as our blood comes in contact and feeds almost every area of our mind and body, supplying oxygen and other phytonutrients.
4. Psycho-spiritual effects: Illumination plant
Gotu Kola has been for a long time the favorite plant of taoists, monks and yogis due to its unique effects on the brain. Many Ayurvedic texts refer to the spiritual properties of the plant, which poetically refer to it as the “Illumination Plant”. Meditators in particular have sought the plant to harmonize the right and left brain hemisphere, which produces an increased awareness, commonly seen by people, that demonstrates what the famous American psychiatrist Mihaly Csikszentmihalyi has popularized as a “state of flux” – a state in which you become heavily focused and absorbed by the work you do, in which all the learning circuits (assimilation) in the brain are significantly improved.
