According to Chinese medicine, anger is hot liver, or hot liver causes anger which is inflammation. Many things cause inflamed liver like chemicals, alcohol, diet, hormones, stress. I had a very high stress job & would take burdock root. It worked great. Bring 1-2 tbsps of the dried root to boil in 1-2 cups water, lower heat & simmer covered with lid for about 10-20 minutes. Remove from heat & drink.
Burdock does many great things like purify the blood &; detox the liver. Highly recommend. If stress related, try GABA with inositol which is also calming. Don't listen to media news, it never changes & we can't change the world, only ourselves, which is where meditation helps.
