Abstract

Ethnopharmacological relevance This study investigates the cognitive enhancing effects of the plant Centella asiatica which is widely used Ayurvedic and traditional Chinese medicine.Aim of the study The goal of this study was to determine the effects of a water extract of the medicinal plant Centella asiatica (CAW) on cognitive ability as well as mitochondrial and antioxidant response pathways in vivo.Materials and methods Old and young C57BL/6 mice were treated with CAW (2mg/mL) in their drinking water. Learning and memory was assessed using Morris Water Maze (MWM) and then tissue was collected and gene expression analyzed.Results CAW improved performance in the MWM in aged animals and had a modest effect on the performance of young animals. CAW also increased the expression of mitochondrial and antioxidant response genes in the brain and liver of both young and old animals. Expression of synaptic markers was also increased in the hippocampus and frontal cortex, but not in the cerebellum of CAW-treated animals.Conclusions These data indicate a cognitive enhancing effect of CAW in healthy mice. The gene expression changes caused by CAW suggest a possible effect on mitochondrial biogenesis, which in conjunction with activation of antioxidant response genes could contribute to cognitive improvement.

  • Preclinical studies have demonstrated that Centella asiatica compounds exhibit antioxidant and anti-inflammatory activities, promote fibroblast proliferation, enhance collagen synthesis, and protect extracellular matrix integrity.

    “Preclinical studies have demonstrated that these compounds exhibit potent antioxidant and anti-inflammatory activities, promote fibroblast proliferation, enhance collagen synthesis, and protect extracellular matrix integrity [16,17,19,22,23,24].”

    From A Randomized, Double-Blind, Placebo-Controlled Trial Assessing the Effects of Oral Centella asiatica Extract on Skin Aging-Related Parameters in Middle-Aged Korean Women. (2026) · cites this paper as [23]

    The Results (page not provided) report that a Centella asiatica water extract increased antioxidant-response gene expression in young and aged mice. The Discussion cautions that the study measured gene expression, not antioxidant function. Our copy does not establish anti-inflammatory activity, fibroblast proliferation, collagen synthesis, or protection of extracellular matrix integrity. (LLM, conf=0.86)

  • CAW treatment (200 mg/kg/d for four weeks) benefits aged WT mice in Morris water maze, object location, and novel object recognition.

    “A treatment benefit of CAW (200 mg/kg/d for four weeks) in WT animals was previously reported both in male and female aged (20 month old) WT mice (as measured by Morris water maze, object location, and novel object recognition) [1,46].”
  • Previous studies show CAW treatment is associated with elevated levels of NRF2-targeted ARE gene transcripts in Tg2576 primary neurons and hippocampus and cortex of young and aged WT mice.

    “Previous studies in our laboratory show that CAW treatment is associated with elevated levels of NRF2-targeted ARE gene transcripts in Tg2576 primary neurons [27], as well as the hippocampus and cortex of young and aged WT mice [46].”
  • Previous studies observed increased hippocampal and cortical mitochondrial gene expression and increased mitochondrial activity in response to CAW treatment.

    “We have previously observed increased hippocampal and cortical mitochondrial gene expression [46] and increased mitochondrial activity [33] in response to CAW treatment.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
