In a state of liver fire flaring upward, foods that add heat can lower the anger threshold. The main things to watch out for are as follows. Alcohol weakens inhibitory circuits and directly raises liver heat, so it is the most important thing to avoid. Excessive caffeine also overstimulates the sympathetic nervous system and increases impulsivity. Spicy, stimulating foods promote fire in Korean medicine terms. On the other hand, heat-clearing foods such as mung beans, lotus root, and chrysanthemum tea, along with adequate hydration and regular meals, help stabilize liver qi.
