Jalap is classified as which type among the following options?

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

Answer: (A)

Jalap is a resin because it is a solid, non-gum plant exudate that is largely free of volatile oil. In pharmacognosy, resins are hard substances exuded by plants, insoluble in water and lacking a significant gum or essential oil fraction. Oleoresins would include essential oil, oleogum resins would contain gum, and balsams are resinous but with notable essential oil content and aromatic characteristics. Jalap’s exudate from the root is predominantly resinous with little to no essential oil or gum, so it fits the resin category best.
