Tragacanth gum

Subject

Tragacanth gum is a natural gum obtained from the dried sap of the Astragalus species (Leguminosae family). While it shares similar uses to gum arabic, it produces more viscous solutions and is more expensive.

Tragacanth gum is exuded from the tree Astragalus gummifer, which grows in desert areas. It is native to parts of Turkey and the Middle East (Iran, Iraq, Khurdistan, and Syria).
