Most natural things don't bother me either. I put Patchouli oil all over me if the mosquitoes are out. I have been using Blue Chamomile oil on clients with inflammation. I use Cedar oil on clients who need some power Chakra work. The Neroli doesn't wash out of the sheets for eternity, so I stopped using that oil. Massage clients don't get anything on their skin that they couldn't eat. Nonetheless, I don't use these things in public so I don't make someone else sick.
Flowers outside in the air are always okay. I did have to move the I. pallidas and Fabian outside. I had cut 3 flowers to ID them with the HIPS pictures and I got pretty stuffed up. Honorabile isn't so smelly.
When I ID my gazillion noIDs, I may have to use an exhaust fan. Or maybe by then I will have a laptop so I can go out to the flowers.
