Gum tragacanth: A natural polymeric backbone

The polymers in the present scenario are the main constituent of the different delivery system. Transdermal patches, ocular drug delivery, nasal drug delivery, mucosal drug delivery etc all are based on the activity of the polymer involved in it. If the polymer is biodegradable in nature it will have a great edge. The biodegradable polymers or hydrogels are totally relaying on the natural backbone. Gum tragacanthis one such material which has varied physiochemical and rheological aspects. In the present review work the assessment of polymeric aspect of Gum tragacanth is highlighted.
