„Using steam distillation, the dried berries of Cinnamomum glaucescens produce the essential oil commonly known as sugandha kokila oil, which is yellow in colour and has a camphoraceous, spicy aroma… However, Non-timber forest products, such as Cinnamomum glaucescens, are over harvested, and if the current rate of collection occurs, may disappear from Nepalese forests.“

Major components of the commercially available essential oil of Cinnamomum glaucescens fruits (with seeds) were 1,8-cineole (13%), methyl cinnamate (14%), α-terpineol (7%) and many mono- and sesquiterpene hydrocarbons. The pericarp oil consisted mainly of 1,8-cineole (56%) and α-terpineol (10%).
