Collection and preparation:
• During drought (dry season of year), bark is fissured and gum exudates
naturally.
• Incisions are made using axe or “sonki”which is moved from inside to outside
to remove bark exposing cambium.
• Cambium forms new phloem protected by gum tears formation as a result of
fermentation .

Uses
• Suspending agent.
• Cough and cold preparations, externally in sore throat and wound healing
preparations.
• It is also used for the treatment of catarrh and diarrhea
• Some studies demonstrate that it can be used as a nontoxic phytochemical
construct in the production of readily administrable biocompatible gold
nanoparticles for Cancer Imaging

Disadvantages:
• It enhances the destruction of many pharmaceutical products (phenols,
vitamins…)

Example cod liver oil
• Why?

Due to the presence of oxidase enzyme
