The palo santo scent is citrusy, green and woodsy. These unique ayurvedic blends are hand-rolled and non-toxic. The sticks burn for about 20 - 30 minutes but their relaxing scent lingers for hours. This fair trade incense is from the original producer of Satya Sai Baba Nag Champa Incense. It is made from dried flowers, herbs, woods and spices.
