Can't find Info on that particular Blend, but there are several others available that do list the contents and all those are blended with pine. Between 30% to 50%.
That makes me wonder if the Blend you all use is not blended with Pine, OR if the Pine isn't actually as dangerous as some people say.
Because after all, the proof is in the pudding , it seems to work well and for a lot of people, too !!
Since I only have a very small collection I might try to hunt down pure cypress if I get a Blood. Or put him on coco.
