Childhood is a critical period for brain development, cognitive maturation and the acquisition of learning skills. Memory, attention, concentration and information processing develop progressively during this stage and influence academic performance and overall development. In Ayurveda, Medhya Rasayana refers to a group of herbs and formulations traditionally used to support intellectual functions, memory (Smriti), comprehension (Dhi) and retention (Dhriti). These preparations have attracted interest as potential complementary approaches to supporting childhood cognitive health.
Important Medhya Rasayana herbs
Classical Ayurvedic literature describes several herbs with Medhya properties. Four commonly recognised Medhya Rasayana plants include:
- Brahmi (Bacopa monnieri): Contains bacosides, which have demonstrated antioxidant and neuroprotective properties. Experimental and clinical research suggests potential benefits for memory, attention and information processing
- Mandukaparni (Centella asiatica): Contains triterpenoids, including asiaticoside and madecassoside. These compounds have demonstrated antioxidant and neuroprotective activities in experimental studies
- Yashtimadhu (Glycyrrhiza glabra): Contains glycyrrhizin and flavonoids, which have been investigated for their antioxidant and neuroprotective potential
- Guduchi (Tinospora cordifolia): Contains alkaloids, diterpenoids and other phytoconstituents associated with antioxidant and immunomodulatory activities
Shankhapushpi (Convolvulus pluricaulis) is another traditionally recognised Medhya herb investigated for its potential effects on cognitive functions.
Potential mechanisms supporting memory and learning
Medhya Rasayana herbs are believed to influence multiple biological pathways associated with cognitive function.
Neuroprotection and antioxidant activity: Oxidative stress can affect neuronal integrity and cellular function. Bioactive compounds in Brahmi and Mandukaparni demonstrate antioxidant properties that may help protect neuronal tissues against oxidative damage.
Synaptic function and memory formation: Bacosides from Brahmi have been investigated for their influence on synaptic activity, neuronal communication and pathways involved in memory consolidation.
Neurotransmitter modulation: Experimental studies suggest that certain Medhya herbs may influence cholinergic and other neurotransmitter systems involved in attention, learning and memory.
Cognitive performance: Their traditional use focuses on supporting Dhi (comprehension), Dhriti (retention) and Smriti (memory), which collectively contribute to learning and information recall.
Clinical evidence in childhood cognition
A randomized, double-blind clinical trial published in 2025 evaluated Brahmi and Mandukaparni in 180 healthy boys aged 8–10 years over 90 days. Cognitive outcomes were assessed using the Post Graduate Institute–Children's Memory Scale (PGI-CMS) and intelligence quotient measurements.1
Both groups demonstrated significant improvements in total memory scores and several memory domains. Brahmi produced a 9.28% increase in mean total memory score, while Mandukaparni demonstrated a 13.45% increase. The study suggested comparable cognitive benefits, with some differences according to Ayurvedic Prakriti.
Clinical considerations
The use of Medhya Rasayana in children requires careful consideration of age, formulation quality, dosage and safety. Herbal preparations should not be administered without appropriate paediatric medical supervision. Potential adverse effects, herb–drug interactions and product contamination also require attention.
Adequate nutrition, quality sleep, physical activity and a supportive learning environment remain essential for healthy cognitive development.
Conclusion
Medhya Rasayana offers an important traditional Ayurvedic approach to supporting childhood memory and learning. Preliminary clinical evidence involving Brahmi and Mandukaparni suggests potential improvements in selected cognitive domains. Nevertheless, further well-designed paediatric trials are necessary to establish long-term efficacy, safety and clinical applicability.2
