Immune herbs are plants traditionally used to support the body's natural defenses against infection and illness. This category covers herbs like echinacea, elderberry, astragalus, and ginger—compounds that contain active molecules studied for their effects on immune cells and inflammatory responses. You'll find information about what research shows regarding how these herbs work, what evidence exists from human studies versus animal research, and where gaps in our understanding remain.

The articles here answer practical questions: which herbs have the strongest research backing, how do they differ in their mechanisms, what doses appear in the studies, and what limitations exist in the current evidence. You'll learn to distinguish between established effects and emerging claims, and understand why some traditional uses have scientific support while others remain unproven.
