Aconitum Fischeri
Also known as Fischer's monkshood.
Aconitum fischeri is a name applied by nineteenth century Eclectic physicians to a monkshood root used as a substitute for the European Aconitum napellus, though the plant they intended is now generally regarded as the same species complex as the Siberian and northern European Aconitum septentrionale rather than a true American native. Monkshoods are perennial herbs of temperate woodlands and mountain meadows across the Northern Hemisphere, and the tuberous root is the part historically prepared. Within the Eclectic and earlier regular medical traditions of North America, this and related aconite species were prized as rapid-acting antipyretics and analgesics, though their extreme toxicity has left them almost entirely out of contemporary herbal practice.
