Myrrh is a very thick and resinous essential oil. In order to get it out of the bottle, it needs to be warmed. Holding the bottle in the palm of your hand for a few minutes and rolling it, is usually enough. If not, sitting it in a hot water bath for a short time should do the trick. DO NOT USE MYRRH IN A HYDROSONIC DIFFUSER. It will clog and ruin your diffuser. It can be blended with other essential oils to the point it will be thinned out enough to be useable in a hydrosonic (water) diffuser.
