That’s awesome. You may also want to look at Artemisia annua for the same reasons, although the compounds in that herb are mostly anti-malarial.....

I’ve tried making ‘smudge’ sticks with vulgaris, but I don’t reckon it burns that well. Which is ironic given acupuncturists use it for moxibustion, but I think it burns better when dried and ground up. We’ve got some growing here also!
