India's traditional medicine system, Ayurveda, has emphasised immune-supporting herbs for millennia — and modern science is validating many of these claims. The advantage of Ayurvedic approaches to immunity: these herbs work through multiple mechanisms rather than a single pathway.
Tulsi and ashwagandha have the strongest clinical evidence for immunity and stress reduction among Ayurvedic herbs. Rather than taking them in isolation, a stacked approach (3–4 herbs combined) is more effective than any single herb.
Key Ayurvedic Immunity Herbs
Tulsi — anti-inflammatory, antimicrobial, antiviral. Ashwagandha — reduces cortisol and stress, supports immunity. Neem — antimicrobial against bacteria, viruses, fungi. Giloy — fever reducer, immunity booster, liver support. Brahmi — balances immunity, antioxidant effects.
