Gotu Kola: Background and Properties
-
Brief History and Traditional Use
Gotu Kola has a rich history in traditional medicine, particularly in Ayurveda and Chinese medicine. It has been employed for its anti-inflammatory, antimicrobial, neuroprotective, and life-extending qualities.
In Ayurveda, Gotu Kola is known as “Brahmi,” which translates to “God-like.” It is believed to enhance brain function, promote mental clarity, and improve memory. In Chinese medicine, it is called “Ji Xue Cao,” which means “herb that strengthens the bones and muscles.” Conditions of the skin, the gastrointestinal tract, and the respiratory system are all treated with it.
-
Chemical Composition of Gotu Kola
Several bioactive chemicals found in Gotu Kola are responsible for the plant’s therapeutic effects. Asiaticoside and asiatic acid are two of the most vital components.
Asiaticoside
Gotu kola contains a potent triterpenoid saponin called asiaticoside. Many pharmacological actions, such as anti-inflammatory, antioxidant, and wound-healing, have been demonstrated.
Asiaticoside has been shown to hasten the recovery time of skin wounds by boosting blood flow and encouraging collagen formation. It may also aid in cognitive improvement and has been demonstrated to have neuroprotective properties.Asiatic Acid
Gotu kola also contains a third triterpenoid component called asiatic acid. Collagen synthesis and wound healing are boosted, and it also possesses anti-inflammatory and antioxidant properties.
Furthermore, asiatic acid has showed promise as an anti-cancer agent. Inhibiting cancer cell development and inducing apoptosis (cell death) have both shown promise in laboratory studies of various cancers (Wu et al., 2017).

Research Studies on Gotu Kola and Neuroprotection
Protection Against Oxidative Stress and Inflammation
Research suggests that Gotu Kola’s antioxidant and anti-inflammatory qualities can shield neurons from damage caused by free radicals and inflammation. Gotu kola extract, for instance, has been shown to lessen oxidative stress and inflammation in the brains of Alzheimer’s disease rats, according to a study published in the journal inflammopharmacology (Giribabu et al., 2020). Gotu kola extract decreased inflammation and oxidative stress in the brains of PD rats, according to another study published in Advances in Pharmacology (Wong et al., 2021).
Effects on Cognitive Function and Memory
Several studies have found that Gotu Kola extract may improve cognitive function and memory in both healthy individuals and those with cognitive impairment. For example, a study published in the journal of Exercise Rehabilitation found that Gotu Kola extract improved cognitive function and memory in healthy individuals (Phoemsapthawee et al., 2022). Another study published in Basic Clinical Neuroscience found that Gotu Kola extract improved cognitive function and memory in rats with Alzheimer’s disease (Sahraei et al., 2022).

Potential Use In The Prevention And Treatment Of Neurodegenerative Diseases
Gotu Kola May Make It Useful In Lowering Alzheimer’s Risk
Gotu kola extract has been shown to diminish beta-amyloid-induced neurotoxicity in cell cultures, suggesting it may be useful as a treatment agent for Alzheimer’s disease, according to a study published in the Journal of Alzheimer’s Disease (Gray et al., 2015). The results of another study on aged rats suggest that Gotu kola extract may be useful in reducing age-related cognitive decline by enhancing cognitive performance and decreasing oxidative stress (Amala Soumyanath, 2012).
Loss of dopaminergic neurons in the brain is a hallmark of neurodegenerative disorders like Parkinson’s disease. Many factors, including oxidative stress, mitochondrial malfunction, and inflammation, contribute to the development of Parkinson’s disease. The loss of dopaminergic neurons is a hallmark of Parkinson’s disease, but recent research suggests that Gotu kola may help guard against this loss.
Gotu kola extract enhanced motor performance and decreased oxidative stress in a rat model of Parkinson’s disease, according to research published in the Journal of Medical Sciences (Lokanathan et al., 2016). Dopaminergic neurons in cell cultures were also protected from oxidative stress-induced cell death by Gotu kola extract, suggesting its potential as a treatment agent for Parkinson’s disease (Orhan, 2012).

Overview of the Mechanisms Of Action
- Antioxidant properties: Gotu kola contains various antioxidants that help to reduce oxidative stress and inflammation. These include flavonoids, triterpenoids, and ascorbic acid, which scavenge free radicals and protect cells from damage.
- Anti-inflammatory effects: The anti-inflammatory properties of gotu kola have been demonstrated by its ability to reduce the generation of cytokines that contribute to chronic inflammation and many illnesses.
- Wound healing: Gotu kola has been used for generations for its beneficial effects on wound healing. It has been demonstrated in studies to hasten recovery times by increasing collagen synthesis and blood flow.
- Neuroprotective effects: Gotu kola’s neuroprotective properties suggest it may be useful for warding off cognitive decline and neurodegenerative conditions. It has been demonstrated to increase levels of BDNF, a neurotrophic factor crucial to cell proliferation and survival
-
Role of Asiaticoside and Asiatic Acid
Two of the key compounds in Gotu kola are asiaticoside and asiatic acid. Asiaticoside has been shown to have wound healing properties and may help to reduce scarring by inhibiting the production of collagen. Anti-inflammatory properties have been observed, which suggests it may alleviate pain and inflammation.
Cognitive decline and neurodegenerative illnesses may be averted with the use of asiatic acid, which has been demonstrated to have neuroprotective benefits. It has been proven to increase BDNF production, which is critical for neuronal survival and development.
-
Effects on Neurotransmitters and Brain-Derived Neurotrophic Factor (BDNF)
In order to promote neuronal growth and survival, gotu kola has been demonstrated to increase the synthesis of brain-derived neurotrophic factor (BDNF). Decreased levels of BDNF have been linked to cognitive decline and neurodegenerative illnesses, where it plays a crucial role in learning and memory.
Gotu kola may also affect neurotransmitter levels in the brain. Studies have shown that it can increase the levels of dopamine, norepinephrine, and serotonin, which are important for mood regulation and cognitive function.
