Overview

Gardenia fruit is familiar in Korean kitchens as a natural yellow food dye (chija-mul), but the Donguibogam records it primarily as a fire-draining medicine for heat lodged in the chest and heart, prized for settling the restless, sleepless irritability that comes with internal heat.

TranslationIts nature is cold, its taste bitter, and it is non-toxic. It mainly treats great heat of the chest, heart, and large and small intestines, heat qi in the stomach, and vexation and oppression in the heart. It removes heat-toxin wind, benefits the five stranguries, unblocks urination, clears the five kinds of jaundice, and stops wasting-thirst. It treats dry mouth, red and swollen painful eyes, redness of the face, wine-flush papules, red nose, and both pale and red forms of scaling skin disease, sores, and counters the toxin of the zhezhong insect.
