Yongdamsagan-tang is a formula that strongly clears heat from the liver and gallbladder and is effective in the acute phase of anger control disorder, but the following cautions are needed. Because of its strongly cold nature, those with weak digestion may experience reduced appetite and abdominal coldness with long-term use. Generally, we review progress every 2-4 weeks and change the prescription. Once symptoms stabilize, we switch to gentler liver-soothing (so-gan) formulas such as Sihosogan-tang. Do not take it on your own for a long period; it must be prescribed under a Korean medicine doctor's diagnosis. If you are pregnant or breastfeeding, be sure to consult before taking it.
