In Chinese medicine, chronic ill-temper is attributed to poor liver function. The liver can get bogged down by a constant influx of toxins in foods and the environment. This can also result in fat storage, digestive issues, and hormone imbalance. If you suspect you have what is called an “angry liver,” start nourishing it with foods like kale, walnuts, beets, lemon, and avocado. A supplement of dandelion root also supports liver function. Drink water and exercise to flush out the toxins. Finally, you should develop a strategy to reduce stress.
