My Herbal PDR copy is a few years old. I need to get a new one. My wife is an MD psychiatrist so I usually bounce my thoughts off her when I get into pharmacology over my head.
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. ;^)
