Background: In Ayurveda, Lehana is a specialized therapeutic practice described under Kaumarabhritya (pediatrics) aimed at enhancing immunity (Vyādhi Kṣamatva), promoting intellectual development (Medhā), and supporting optimal growth and digestion in children. It involves the administration of selected herbs and formulations such as Ghṛta, Madhu, Swarna Bhasma, and Medhya Rasāyanas in suitable vehicles, tailored to the child’s age, constitution, and health needs. The classical references in Kāśyapa Saṁhitā, Charaka, and Ashtānga Hṛdaya highlight Lehana as a preventive and promotive measure essential in early childhood.

Aim and Objectives: To explore and analyze the role of Lehana in enhancing immunity and neurodevelopment in children from an Ayurvedic perspective, with emphasis on classical indications, formulations, and modern relevance.

Materials and Methods: This is a literary review based on classical Ayurvedic texts including Kāśyapa Saṁhitā, Charaka Saṁhitā, Sushruta Saṁhitā, and Ashtanga Hṛdaya, along with modern pediatric literature and relevant research papers. The study focuses on the pharmacological and therapeutic aspects of commonly used Lehana Yogas, particularly their effects on Agni, Ojas, Medhā, and Bala in children.

Observations and Results: Classical Lehana practices such as Swarnaprāśana, Ghṛta-Madhu Lehana, and Medhya Rasāyana formulations were found to support digestive strength, memory, speech, immune response, and growth patterns in children. These formulations align with modern research on immunomodulation, antioxidant activity, and neurocognitive enhancement. The analysis highlights the potential of Lehana as a safe, non-invasive, and culturally acceptable intervention in pediatric healthcare.

Conclusion: Lehana holds a significant place in Ayurvedic pediatric care for boosting immunity and supporting neurodevelopment. Its rational use, based on individual constitution and developmental stage, may serve as an effective adjunct or alternative to modern nutritional and neuroenhancement strategies. Further clinical validation can support its integration into contemporary child health models.
