Zukoh is a finely ground powder made from the same ingredients that fine incense is made of: cinnamon, cassia, clove, sandalwood, borneol, star anise, etc. Buddhist monks have used it for centuries for purification before ceremonies, preparing meals, or even touching another person. It has its origins in ancient India where hygiene and spreading germs was a major concern. It can be rubbed on any pulse point, behind your ears and/or used on your hands. It has a very natural fragrance. It can be rubbed between the palms for hand sanitation. Zukoh can also be burned as incense using Koh Do style. It can be burned on charcoal, makko, or used in incense formulas.
