Gyeongokgo is a traditional tonic made of rehmannia, poria, ginseng, and honey, and was favored even in the Joseon royal court. Its key effect is replenishing lung-kidney yin deficiency, a state in which the yin energy and fluids of the lungs and kidneys have been depleted. It suits those with dry skin, a frequent dry cough, a dry mouth, and a sense of accelerated aging.

Traditional Korean Medicine Perspective

At Dongjedang Korean Medicine Clinic, we use Gyeongokgo as a tonic on a different axis from Gongjindan. If Gongjindan opens and fills, Gyeongokgo moistens and replenishes. Gyeongokgo is more suitable for those whose bodies are hot and dry with insufficient fluids, or for those who have lost much of their body fluids after a serious illness or chemotherapy.
