Balsam of Copaiba is classified as which type of exudate?

• A. Resin
• B. Oleoresin
• C. Oleogum resin
• D. Balsam

Answer: (B)

Plant exudates are grouped by what they contain: resins are solid, non-volatile substances; if a resin carries a volatile essential oil, it becomes an oleoresin; if an exudate also has gum, it’s an oleogum resin; balsams are resinous substances rich in essential oils and resin acids. Balsam copaiba from Copaifera trees is a resinous exudate that includes a significant volatile oil, so it is classified as an oleoresin. This combination explains its semi-fluid to liquid nature and characteristic aroma, setting it apart from a pure resin, a gum-containing exudate, or a true balsam.
