Hybridises with : Canadian Fleabane

Blue Fleabane can releive tooth-ache and arthritic pains.

A new diterpene, acetylarabinoside, has been found in Blue Fleabane.

Blue Fleabane contains derivatives of aromadendrane-type sesquiterpenes, such as 4alpha-10beta-alloaromadendranediol and 4beta-10beta-aromadendranediol. The Aromadendrane skeleton is shown with the three fused rings, one a three, another a five and the third a seven-membered ring bearing a resemblance to the Tigliane Series. Alongside it is one of the Aromadendranes found within Blue Fleabane.
