It does sound like yarrow is worthy of investigation, but in the absence of NMCD info I’d need to at least do a review of the scientific literature before I could recommend it to my patients. I’m sure you understand why my advice must be...conservative. ;^)
LOL..... I am conservative as well. I understand. In the interim, yarrow sure is a beautiful flower in my fields.
I grew up with Native American blood on both sides of my parent’s ancestry. Both my parents knew the wild plants and herbal lore better than anyone I ever met. People are now trying to learn the same knowledge of edible wild plants that we ate on our table all the time.
Currently, my focus is neuroscience research, thus I can understand how the biochemistry of the old ways had merit.
