What is Chinese White Olive (Qing Guo)?

Chinese White Olive (qing guo, 青果) , also known as Fructus Canarii, is the ripe fruit of Canarium album, an evergreen tree belonging to the family Burseraceae. Canarium album is a famous subtropical fruit tree that is native to Southern China, and has at least 2000 years of cultivation history. 

Found in China, Japan, Vietnam, Laos, Cambodia, Thailand, Myanmar, India, and Malaysia, Canarium album has many medicinal and commercial uses. Chinese White Olive was first recorded in Ri Hua-Zi’s Collected Materia Medica (Ri Hua Zi Ben Cao, 日华子本草) during the Five Dynasties and Ten Kingdoms (907 AD – 979 AD). Other than being used to make items such as furniture, farm tools and construction materials, its ripe fruits are gathered every autumn for medicinal usage.

In addition, Chinese White Olive is also eaten as food, and used as an ingredient in Southeast Asia dishes such as Khao phat nam liap.
