Ginseng and Deodeok: Two Roots That Look Alike but Aren't

Sliced and dried, ginseng and deodeok can look confusingly similar. The Donguibogam draws the line between them not by appearance, but by which direction they push the body.

Ginseng (人蔘) and deodeok (沙參, Adenophora root) are different plants, but as dried, sliced root — the form most people actually encounter — they can look close enough to confuse a non-specialist. The Donguibogam itself addresses this pairing directly, and the distinction it draws has nothing to do with appearance.

The same direction, opposite temperature

A citation the Donguibogam preserves from the physician Zhu Danxi states it plainly: ginseng is bitter and slightly warm, tonifying the yang of the five viscera, while deodeok (사삼) is bitter and slightly cold, tonifying their yin. Both are framed as tonics for the same general category of deficiency — but pointed in opposite directions, one warming, one cooling.

Why this pairing shows up as a caution, not just a comparison

This distinction appears in our sources specifically as guidance about substitution: for someone with a lingering cough or a constitution already running hot, the same source recommends using deodeok in place of ginseng, precisely because ginseng's warming action was thought to aggravate 'lung fire' in that situation. In other words, the two roots aren't interchangeable substitutes for convenience — the choice between them was itself part of the traditional diagnosis.

Two roots, two separate pages

We keep this distinction intact by documenting each root on its own terms: ginseng's entry and deodeok's entry record different natures, different classical uses, and this same caution about when one was traditionally preferred over the other.
