Inula graveolens

Inula graveolens is harvested mostly in Corsica. It is an annual plant that has so far escaped cultivation. There are years when the wild plant is not very abundant and distillers forgo harvesting. 

Inula graveolens is spectacularly effective in ridding the lungs of excess mucous, be it caused by chronic bronchitis or cystic fibrosis. Inula also helps to eliminate pathogenic pollutants that have been inhaled, such as smoke, dust, flour etc. The oil derives its properties from an unusual mix of components including a high concentration of bornyl acetate and smaller amounts of sesquiterpene lactones. Modern French aromatherapy credits the oil with excellent efficacy in the context of cystic fibrosis, heart palpitations and COPD.
