White sage is both antimicrobial and antibacterial, and helps to repel insects.

Also can be used as a ritual tool to rid yourself or your space  of negativity. This includes past traumas, bad experiences, or negative energies from others  and  improving  your mood. 

Burning white sage step by step:

Open a window or door before you start burning the sage. This allows the smoke to exit your house.

Put the sage in the burning container and light it. Let it burn for several seconds and then blow it out so that it keeps smoking. 

Walk to each room you wish to purify and let the smoke enter it. Do not allow any space to fill with too much smoke. Avoid inhaling the smoke directly.
