Bai Yao Jian is a multiherb concoction containing Wu Bei Zi, tea and other ingredients. It is hard to obtain and usually replaced with Er Cha in prepared versions in Japan and Taiwan. In the UK it has to be replaced due to the prohibition on animal products which applies to Wu Bei Zi, being the product of an insect's interaction with a Chinese Sumac tree.
