Beer is bitter and cool in nature. Beer clears away heat and can temporarily promote movement of qi and blood circulation. Drinking beer in moderation can be a short term tonic to stimulate the kidneys, which may help chronic kidney inflammation, by clearing dampness and phlegm in the system. However this is only a short term solution and should not be a prolonged answer. Long term alcohol abuse will damage the stomach, kidneys, liver and heart and is very damaging to the whole body and mind.
