Just for follow up, my friend told me the dried yarrow I gave her helped! :yahoo: I had recommended she merely tuck a pinch between the cheek and gum, and not directly into the fractured tooth (as it could get trapped in there and make it worse) and it worked. The pain, inflammation, and swelling went down.
In another case, I had given some yarrow to some relatives for other general use. A friend of theirs visited with a bad tooth. My relatives gave him a pinch of yarrow, and it helped him get through an entire shift at his work. Later, after having the tooth extracted by a qualified dentist, he returned for more yarrow to help with the residual pain from the extraction.
It’s neat to know I can help people with my knowledge of herbs! 🙂
