Palo Santo has been used by people of many cultures over the centuries to purify the energy of themselves, loved ones, or their homes. Palo Santo comes from the Palo Santo tree found in Peru, Ecuador, and several other countries in Central and South America. The high resin content of Palo Santo wood is believed to have purifying properties when it’s burned, hence why it is used to cleanse negative energy and purify spaces as well as people. Its sweet scent is said to be relaxing and helps relieve stress. Palo Santo can also be used to repel bugs.
