In aromatherapy, Myrrh has been known to aide with relief for colds, congestion, coughs, bronchitis, and phlegm. These doses are typically in essential oil form, however. As well as using it as an incense or spiritually, several medical journals have confirmed it may help with the following also:
Kill Harmful Bacteria
May Support Oral Health
Supports Skin Health and May Help Heal Sores
Combats Pain and Swelling
May Be a Powerful Antioxidant
 
It is said to have a sedative scent and inhaling it has been known to lift negative moods, promote the feeling of being grounded, and encourage the feeling of spiritual awakening. Thus more often, we tend to use it in many of the Millenheirs hair and skin products but also burn it in several of our blends. 
To burn: Light Charcoal, place in flameproof container, place a bit of resin on charcoal.
