Body systems

Immune System

The body’s defence network — barrier tissues, white cells, and lymphoid organs that detect and clear pathogens.

General herbal approach

The herbal toolkit splits into two complementary strategies. Immunomodulators and deep immune tonics (astragalus, reishi, medicinal mushrooms) are taken over weeks to months to train and strengthen baseline resilience. Immunostimulants (echinacea) are used acutely at the first sign of infection to rally a rapid response. Alongside these, antimicrobials, antivirals, and diaphoretics help the body meet and move through an active infection, while lymphatics and alteratives support clearance and recovery.
