Clinical commentary 臨床
Mahwang-tang's hot-natured twin — Gyeji swapped for cold Seokgo, converting a cold-dispersing formula into the definitive treatment for heat wheezing. Four herbs demonstrating that one substitution can reverse a formula's temperature. — Eui Young (Justin) Chung, L.Ac., Dipl. O.M.
