Inula is a most powerful mucolytic essential oil helpful for all respiratory and lung issues. It is known to ease asthma and bronchitis symptoms. As a cardio-tonic it will regulate blood pressure as it calms and eases the nerves. With such an affinity to Inula and wanting to share the incredible health values I need to be absolutely certain of the safety. I research all of what I work with and create with, yet this is one essential oil I rely on for personal medicine. That is my choice, I am not suggesting that one do this unless they have adequate knowledge; they then have the free will to use these products for personal health care choices. I have researched the safety and chemistry of this very potent and extraordinary effective plant oil. In the Essential Oil Safety Guide by Tisserand and Young it states that there Inula has no known level of toxicity or adverse skin reactions. Also of note is that they mention that there is limited availability of this substance. The value of this lovely healing botanical to me though is priceless for immune enhancement and restoring respiratory wellness. When we are healthy we are vibrant. When we breathe fully our chi flows; allowing our selves to be living, not just surviving. I prefer to emphasize the positive, yet some of the conditions in this world can be harsh and downright toxic unfortunately. Fortunately Inula assists with creating a personal field of wellness as we inhale the essence and better yet when we incorporate the essential oil in therapeutic formulations for direct body applications.
