The smell of sage is thought to release negative ions that help to improve the symptoms of allergies. This is especially helpful for allergies related to pet dander, dust, pollution, and mold. The scent may also be useful for those with asthma or other respiratory conditions, but you should be sure not to inhale the smoke directly if you do have a breathing condition.
Burning sage incense may also help to relieve negative moods, dispel negative energy, and bring spiritual clarity to a room. Additionally, the scent of sage can soothe stress and anxiety, making sage incense a perfect thing to burn before turning in for the night.
