Known Hazards

Hedysarum boreale mackenzii is widely regarded as toxic and warnings about confusing it with its edible cousin Hedysarum alpinum Richardson (Eskimo potato) abound. After exhaustive research, no chemical basis for toxicity could be found. In addition, a critical examination of the literature could find no credible evidence that the species is toxic in spite of these widespread rumours[
