In traditional Chinese medicine anger covers a wide range of related emotions and should be perceived in an extensive broader sense. It incorporates emotions such as irritability, impatience, frustration, stubbornness, rudeness, arrogance, resentment, aggression, rage, and suppressed anger - depression and apathy.
There is active, explosive anger, which can be labeled “hot anger” and passive, repressed anger that can be labeled “cold anger”. "Hot anger" manifests with "heat signs", while "cold anger" manifests with "cold signs". Active, explosive, "hot anger" makes the Qi rise upward (as heat flares upward) and symptoms manifest predominantly in the head. Typical symptoms of active anger are red face and cheeks, dizziness, headache. Other symptoms could include heart palpitations and rapid pulse, ringing in the ears, thirst, etc. Passive, repressed, "cold anger" manifests with "cold signs" such as paleness, lack of energy, lack of mood, apathy, depression.
On a mental level the best way to counteract anger is to practice patience.
