Pu-Erh has been said to have a wide range of health benefits. Ripe pu-erh especially is known to be good for the digestion, and is often drunk after meals in China. This makes it a wonderful replacement for coffee for drinkers with sensitive stomachs or gastrointestinal disorders such as acid reflux. It can also be drunk throughout the day, even before bedtime, as its caffeine boost is significantly more mellow than other teas.
