Grows primarily on the trunk and branches of oak trees, but is also commonly found on the bark of other deciduous trees and conifers such as fir and pine. Oakmoss is commercially harvested in countries of South-Central Europe and usually exported to the Grasse region of France where its fragrant compounds are extracted as oakmoss absolutes and extracts. Its use in perfumes is now highly restricted by International Fragrance Association regulations, and many scents have been reformulated in recent years with other chemicals substituted for Oakmoss. Oakmoss should be avoided by people with known skin sensitization issues.
