Immunomodulation in Ayurveda: a Comprehensive Review
Year: 2026
Type: article
Study design: Systematic Review
Abstract: Background: The immune system involves a complex interplay of cellular and humoral components that protect the host against pathogens and maintain homeostasis. In Ayurveda, the concept of immunity is encapsulated in terms like Vyadhikshamatva (disease resistance) and Ojas (vital essence). As global health paradigms shift towards preventive medicine, the immunomodulatory potential of Ayurvedic herbs and formulations (Rasayanas) has garnered significant scientific interest. Methods: A systematic search was conducted using databases including PubMed, Scopus, Google Scholar, and the DHARA interface. Keywords included "Immunomodulation," "Ayurveda," "Rasayana," "Vyadhikshamatva," and specific medicinal plants. Classical texts (Charaka Samhita, Sushruta Samhita) were reviewed for theoretical frameworks. The study synthesises data on pharmacological mechanisms, in vitro/in vivo studies, and clinical applications. Results: Ayurvedic immunomodulation functions through three primary dimensions: Rasayana (rejuvenation), Vyadhibala Virodhitvam (attenuating disease progression), and Vyadhikutpadaka Pratibandhakatvam (preventing disease origin). Key herbs such as Withania somnifera (Ashwagandha), Tinospora cordifolia (Guduchi), and Emblica officinalis (Amalaki) demonstrate dual capabilities: immunostimulation against infections and immunosuppression in autoimmune conditions. Mechanisms include the modulation of cytokine expression (IL-2, IFN-γ, TNF-α), regulation of oxidative stress via antioxidant pathways, and influence on the gut microbiome (Agni). Polyherbal formulations like Chyawanprash show synergistic effects on Natural Killer (NK) cell activity. Conclusion: Ayurvedic immunomodulators offer a holistic approach to host defence, distinct from the specific antigen-antibody focus of modern immunology. By stabilising the neuro-endocrine-immune axis, these interventions hold promise for integrative management of immunodeficiency, cancer, and autoimmune disorders. Further standardised clinical trials are essential to validate these mechanisms globally.
