What is Centella asiatica?
Centella asiatica is a perennial herbaceous plant from the Apiaceae family that grows in tropical and subtropical regions. The plant, also known as "Indian Suteki" in Türkiye, has been used as both a food and medicinal plant in South and Southeast Asia for thousands of years. in ayurveda mandukparni, in traditional Chinese medicine Ji Xue Cao It is called by name.
The main bioactive power of the plant is asiaticoside (asiaticoside), madecassoside (madecassoside), asiatic acid And madecassic acidIt originates from pentacyclic triterpenoids formed from These compounds have versatile effects on both the nervous system and connective tissue.
Brahmi Confusion - Important Note
Do not confuse Bacopa monnieri with: In India, both Centella asiatica and Bacopa monnieri are occasionally referred to as "Brahmi". This causes serious confusion on product labels. The two are different plants, with different mechanisms and profiles. When purchasing centella asiatica or Bacopa monnieri Check the Latin name.
Mechanisms of Effect
1. BDNF and Neuroplasticity
asiaticoside and madecassoside in animal models BDNF (Brain-Derived Neurotrophic Factor) It has been shown to increase dendritic elongation and synaptic plasticity. This effect is evident in the hippocampus region, which is critical for learning and memory consolidation.
2. Anxiolytic and Calming Effect
It is suggested that Centella asiatica extracts positively affect the GABAergic system. There is evidence that it reduces markers of anxiety in both animal studies and human pilot studies. With this feature, it exhibits an adaptogenic plant profile; By balancing the stress response, it provides a calming-focusing profile, not an energy-lowering one.
3. Brain Microcirculation and Vascular Support
Triterpenoids are known to improve endothelial function and support capillary integrity. Strengthening brain microcirculation indirectly supports cognitive performance by improving neuronal oxygen and glucose supply. This effect also contributes to connective tissue health by increasing collagen synthesis.
4. Antioxidant and Neuroprotective Effect
It has been reported that Centella asiatica components have a protective effect against oxidative stress and reduce amyloid-beta accumulation in animal models. These findings are interesting for research on age-related cognitive decline; however, the number of robust RCTs (randomized controlled trials) confirming it in humans is still limited.
Traditional Use
In the Ayurvedic tradition, Centella asiatica, Medhya Rasayana It is in the class of plants that strengthen the mind. Used for memory, focus and longevity; He has also been accepted as a supporter of meditation. Its fresh leaves are consumed as food in Southeast Asia; It is served as "gotukola sambol" in Sri Lanka.
Clinical Evidence
Human studies are still in the early stages; However, some controlled studies provide promising findings. Wattanathorn et al. (2008, Journal of Ethnopharmacology) reported that Centella asiatica standardized extract improved attention and cognitive processing speed in healthy elderly individuals. Bradwejn et al. (2000) evaluated its anxiolytic potential through acoustic startle response.
⚠ Limitation of Evidence
Level of evidence: There are few large-scale, double-blind RCTs for use in cognitive enhancement in healthy young individuals. Available data are predominantly based on older individuals, animal models, or small pilot studies. The evidence for a strong nootropic effect is more limited compared to Bacopa monnieri.
Dosage and Usage
| form | Daily Dose | Notes |
|---|---|---|
| Standard extract (10% asiaticoside) | 500–1000 mg/day | The most commonly used in studies |
| Raw grass / dry leaves | 2–4 g/day | Bioavailability variable |
| Highly concentrated extract (40+%) | 100–200 mg/day | Dosage should be adjusted carefully |
The effects of Centella asiatica are chronic and cumulative; for significant effect in most studies 4–8 weeks of regular use It is recommended. Since it contains fat-soluble components, taking it with food may increase bioavailability.
- Combination with Bacopa monnieri: Both herbs are used together in traditional Ayurvedic formulas; Synergy of memory and attention has been reported.
- Combination with Ashwagandha: Adaptogenic profiles complement each other, recommended for stress-cognitive balance.
- Combination with Ginkgo biloba: A synergistic effect on vascular support and microcirculation is expected.
Safety and Side Effects
Centella asiatica is generally considered safe as it has been consumed as food for centuries. Rare side effects are usually observed with high doses and long-term use.
| Possible Impact | frequency | Management |
|---|---|---|
| Nausea/digestive upset | rare | Take with food |
| Headache/dizziness | very rare | reduce dose |
| Liver enzyme elevation (high dose) | very rare | Avoid prolonged high doses |
| Allergic skin reaction (topical) | rare | Internal use generally safe |
⚠ Special Cases
Situations to be considered: There is no sufficient safety data for use during pregnancy and breastfeeding. It is recommended that those with liver disease avoid high doses of the extract. Caution should be exercised in combination with sedating drugs (benzodiazepine, etc.). This content does not constitute medical advice.

Frequently Asked Questions
Centella asiatica; It supports cognitive health with its versatile effects such as BDNF increase and neuroplasticity support, anxiolytic/calming effect, strengthening of brain microcirculation and neuroprotection. In Ayurveda, it is included in the 'Medhya Rasayana' class of plants that strengthen the mind.
No, they are different plants. Although both are occasionally called 'Brahmi' in India, Centella asiatica (Apiaceae) and Bacopa monnieri (Plantaginaceae) are completely different species. Be sure to check the Latin name when purchasing a product.
For the standard extract (10% asiaticoside), 500–1000 mg per day is a common usage range. Considering that the effect is cumulative, regular use of at least 4–8 weeks is recommended. Taking it with food may increase bioavailability.
Since it is a plant that has been consumed as food for centuries, it is well tolerated in general use. In rare cases, digestive complaints or elevated liver enzymes have been reported with very high doses. It is recommended to be careful during pregnancy and breastfeeding, liver patients and those using sedative drugs.
Most effects are chronic and cumulative. Studies have evaluated 4–12 weeks of regular use for attention and cognitive improvement. As with herbal adaptogens such as Bacopa monnieri, the expectation of rapid (acute) effects is unrealistic.
