White sage can help with cleansing negative energy, spirits and even cleanse the air or airborne virus. When smudging with sage remember to keep a door or window open while doing so. It's is also best to follow up with Dragon Blood, Frankincense, Myrrh, Palo Santo or even Florida Water to bring in the positive energy. It is not wise to smudge with sage daily because you will also get rid of the positive energy just as much as the negative energy. Never leave sage while burning. 4-5inch stick
