Four Constitutions. One System.

Korean Medicine has understood for centuries what Western wellness is only beginning to ask: that no two bodies need the same thing. Its answer is constitution — a lifelong pattern of yin and yang that shapes how your body holds heat, releases tension, and returns to rest.

There are four. TAE-YIN and SO-YIN, the greater and lesser yin. TAE-YANG and SO-YANG, the greater and lesser yang. Each moves with one of the five elements and one season of the year. Earth, the fifth element, sits at the center — the still axis the other four turn around.

Find yours by your birthday. Then run the bath.
