Burning sage is an ancient practice that removes negative energy from your area. It has also been said to to have antibacterial components. 

To burn sage, light the end until it glows, and along with a dish to catch the ask and/or falling embers carry throughout your home wafting the smoke into corners and throughout your living area. PLEASE open a window/door during this so you do not ‘smoke yourself out’. Can cause asthma reactions, please burn with extreme caution.
