Research Gist
This review gathered the published evidence on Centella asiatica and its effects on the nervous system. It covers the plant's traditional use in Ayurveda as a brain tonic alongside the modern research that has examined those claims. The review discusses antioxidant activity, protection of neurons against various insults, and specific work on dopamine neurotoxicity relevant to Parkinson's research. The author notes that while preclinical evidence is reasonably consistent, human cognition trials have been modest in size and produced mixed results. This makes the review useful for understanding what is and is not established.
