Medicinal Plants
If you grow Panax ginseng or use root extracts, this decade-long review explains the actual cellular reasons behind the herb's centuries-old reputation as a body-balancing tonic rather than a simple immune booster.
Red ginseng is made by steaming and drying the root of the ginseng plant, a traditional practice in Asian medicine. Researchers pulled together a decade of lab and human studies and found the processed root doesn't just push the immune system in one direction: it can calm an overactive immune response or perk up a sluggish one, depending on what a person's body needs. The effects trace back to specific compounds in the root, including rare ginsenosides and complex sugars, that interact with immune cells like macrophages and T cells.
Key Findings
Review covers clinical and preclinical studies on red ginseng's immune effects published from 2015 to 2025
Key bioactive compounds identified include rare ginsenosides, polysaccharides, and Arginyl-Fructose, which act on both innate immune cells (macrophages, dendritic cells, neutrophils) and adaptive immune cells (T and B cells)
Effects operate through multiple signaling pathways including TLR4/NF-κB, RORγ, glucocorticoid receptors, and gut microbiota interactions

A 10-year review of research finds that red ginseng, a steamed and dried preparation of Panax ginseng root, can both boost and calm the immune system depending on a person's health status, supporting its long traditional use for building resilience.
