Q Why does my child catch colds so often?
A When Lung Qi (폐기허) and Spleen-Stomach weakness deplete Defensive Qi (衛氣, Wei Qi), the body cannot ward off external pathogens.
Detailed Answer
Frequent colds are not simply a matter of low immunity — they reflect an overlapping constitutional issue of Lung Qi deficiency (폐기허), Spleen-Stomach weakness, and insufficient Defensive Qi (衛氣, Wei Qi). Defensive Qi acts as a protective energy layer along the skin and mucous membranes, shielding the body from external pathogens. When it is depleted, even minor seasonal changes or temperature fluctuations can trigger a cold.
Korean Medicine Clinic Perspective
At Dongjedang, we approach this by restoring respiratory mucosal defenses through formulas based on Yuping Feng San (玉屏風散 — Astragalus/황기, Atractylodes/백출, Siler/방풍), which strengthen both Lung Qi and Defensive Qi.
