Hey, Shari - first of all thank you so very much for your support and donation to our cause under our friend, Claire's, Fishyculture raffle. " A friend in need, is a friend, indeed!" Secondly, I share your avid interest in medicinal herbs and regularly use greenmedinfo.com as an excellent online resource of peer-reviewed literature on all things healthwise, including medicinal herbs. And finally, for some more formal training, here is https://theherbalacademy.com/ in case you are interested. In any case, again, thank you from Bear and me.
