Overview

Tofu is one of the most common foods on the Korean table today, but the Donguibogam classes it as having toxicity — not in the modern sense, but as a classical caution about its cooling, qi-stagnating nature when eaten to excess. The text's warning about overeating tofu with alcohol is a striking, very specific piece of dietary advice from four centuries ago.

In the Donguibogam

性平一云冷, 味甘, 有毒. 益氣和脾胃.
Source: Donguibogam, Tangaek-pyeon (Herbology volume)
TranslationIts nature is neutral (some say cold), its taste sweet, and it has toxicity. It benefits qi and harmonizes the spleen and stomach.

Traditional functions

  • Benefits qi
  • Harmonizes the spleen and stomach

Traditional applications

  • General digestive harmonization
  • Everyday plant-protein nourishment

Traditional preparation

Eaten cooked in soups, stews, and side dishes as a daily food; the classics recommend moderation, especially alongside alcohol.

Cautions

Caution: The Donguibogam records tofu as having toxicity in the classical sense: its cold, qi-stagnating nature can trigger kidney-qi disorders, wind-type headache, and sores/scabies if overeaten. It gives an unusually specific warning that overeating tofu together with alcohol can cause dangerous bloating, worsened by drinking, and traditionally treated by drinking cold water. This reflects a four-century-old dietary caution, not a modern food-safety finding — tofu is a normal, safe food in moderation today. Consult a professional if you have concerns.
