Does Ashwagandha affect immune health?

Ashwagandha has a positive effect on immune health, mainly through the following mechanisms:

Enhancing immune cell function: Ashwagandha can increase the activity of immune cells such as natural killer cells, T – lymphocytes, and macrophages. Natural killer cells are crucial for the body’s innate immune response, capable of directly killing virus – infected cells and tumor cells. T – lymphocytes play a central role in cell – mediated immunity, while macrophages are responsible for phagocytosing pathogens and presenting antigens. By enhancing the function of these immune cells, Ashwagandha helps the body better identify and eliminate foreign invaders, thereby strengthening the immune defense.

Modulating cytokine production: Cytokines are important signaling molecules in the immune system. Ashwagandha can regulate the production of cytokines, such as increasing the production of anti – inflammatory cytokines like interleukin – 10 (IL – 10) and decreasing the production of pro – inflammatory cytokines like tumor necrosis factor – alpha (TNF – α) and interleukin – 6 (IL – 6). This helps maintain a balanced immune response, preventing excessive inflammation that can damage tissues and organs.

Antioxidant effects: Oxidative stress can damage immune cells and affect their function. Ashwagandha contains antioxidant compounds that can scavenge free radicals, reduce oxidative stress, and protect immune cells from damage. This allows immune cells to function properly and contribute to a healthy immune system.
In summary, Ashwagandha can enhance immune health by influencing various aspects of the immune system. However, more research is needed to fully understand its mechanisms of action and to determine the optimal dosage and usage for different individuals.
