Ampelopsis grossedentata, commonly known as moyeam, is a species of plant in the Vitaceae family. It is mainly distributed in central and southern China, but can also be found in some southeast Asian countries. The leaves and stems are used to make a herbal tea called "moyeam". The product has been popular in China for generations and is now consumed in some other countries. The English name "moyeam" comes from the Chinese name "茅岩莓". Most moyeam is grown on Zhang Jiajie, a mountain in Hunan Province in central China.
