Glycyrrhizin IV delivers a licorice-derived compound to support liver function and general condition. It is understood to calm inflammatory responses and protect liver cells. Its approved indications in Korea are improving liver function and easing allergy symptoms; fatigue recovery is a use outside that.

Once a week is recommended. When you feel it varies between people, because the experience differs for someone whose liver values were poor to begin with and someone using it for general condition. How many sessions to have is decided from the purpose and test results.

Heavy long-term use can raise blood pressure or cause swelling, because the licorice component acts to retain sodium in the body. You must disclose high blood pressure beforehand, and if you plan to repeat it over a long period, monitoring blood pressure and electrolytes as you go is the safe course.
