Karaya is a very 'gummy' gum that has mucilaginous properties when wet. It is sometimes known as Indian Tragacanth as it is employed similarly as a 'sticking' agent. This property can be incorporated into incense blends' though it is less useful for binding oils than Gum Tragacanth. In India it is largely valued for its medicinal properties. When burnt it emits a pungent smell, which is most suitable for banishing and exorcism blends.
Since people first came together to honour the Gods and spirits of nature they used gums, resins and fragrant herbs to bring them closer to the divine beings and to give fragrant wings to their prayers. Every culture has their own sacred herbs that are particular to its region, yet, precious incense herbs and gums have also always been traded far beyond their country of origin.
