Nag Champa
Nag Champa is the name for a group of fragrances. It contains a high concentration of sandalwood. Usually found as incense sticks or cones.
Nag Champa belongs to the "Champa" class of Indian incense, originating from the Champa flower. Champa incenses contain a natural ingredient indigenous to India called "halmaddi", which is a semi-liquid resin taken from the Ailanthus Malabarica tree. It is what gives Nag Champa its characteristic grey color. Halmaddi is hygroscopic which means it absorbs moisture from the air. This can cause Nag Champa incenses to have a wet feeling to them.
