Palo santo, which translates literally to “holy wood” in Spanish, is the harvested wood from palo santo trees which are found primarily in South America and in some regions of Central America. They're part of the citrus family, with a relation to frankincense and myrrh. It has a woody scent with hints of pine, lemon, and mint. Thanks to its high resin content, palo santo wood is believed to release its purifying properties when burned. In the Shamanic history of South America, palo santo is said to remove negativity and obstacles and attract good fortune. Over the years, smudging has been used more commonly and is said to get rid of negative energy, restore harmony, and connect us to a spiritual plane. In other words, doing so could make you feel more balance. 
To cleanse any space’s energy, simply light a stick and then extinguish the flame, gently waving the stick in the air or waving your hand over the stick. White smoke will be emitted from the smoldering stick, which can disperse around you or your space.
The price is for one 4 inch stick.
