Q Do herbal tonics really help with immunity? I catch colds often—will they actually help?
A The key herbs in tonics—deer antler, astragalus, and ginseng—have research-confirmed effects on immune cell activation and immune regulation. Strengthening the spleen-stomach and Lung Qi often improves frequent colds and respiratory weakness together.
Detailed Answer
Astragalus (黃芪) has been confirmed in multiple studies to activate NK (natural killer) cells and regulate immunity. Ginseng is well known for boosting immunity and reducing fatigue, while deer antler helps with blood formation and immune strengthening. People who catch colds frequently often have Lung Qi deficiency or spleen-stomach weakness as the underlying cause, so replenishing these with a tonic reduces minor recurring illnesses.
Our Korean Medicine Clinic's Perspective
At Dongjedang Korean Medicine Clinic, when prescribing tonics for immune strengthening, we focus on reinforcing Lung Qi and spleen-stomach function. Many patients who start taking it right before seasonal transitions get through winter without catching a cold.
