Palo Santo sticks are a type of incense wood that has been used as a talisman and to purify the air. The scent is released by the smoke when the incense is burned and then extinguished. The scent is similar to that of lemon and mint. (Because it is burned, the scent is similar to that of a bonfire, and there is also a slight smoke smell. It is similar to incense.) The scent will vary slightly depending on the manufacturer, but it is a good product to try out if you are wondering what Palo Santo is like. I think it's a good product to buy and try out first. One of the things I recommend is that it doesn't use artificial fragrances.
