Hedysarum alpinum flower. This plant is a perennial herb producing several erect stems from its caudex. It grows to 70 centimetres (28 inches) in height. The taproot is thick and woody, and it has rhizomes which can produce new stems. The leaves are each divided into a number of leaflets up to 3.5 centimetres (1.4 inches) long.
A sample of fresh Hedysarum alpinum seeds was sent to a laboratory for HPLC analysis. Results showed that the seeds contained 0.394% beta-ODAP by weight, a concentration well within the levels known to cause lathyrism in humans, although the interpretation of the results has been disputed by other chemists.

Hedysarum species are used as food plants by the larvae of some Lepidoptera (moth and butterfly) species including Coleophora accordella.Some species, such as Hedysarum alpinum also known as Alpine sweetvetch or wild potato, were eaten by the Inuit to help ward off the effects of scurvy due to it being rich in vitamin C, containing about 21 mg/100g.
The Eskimo potato is a type of edible plant that grows in the northern areas of Canada and Alaska. The plant's scientific name is variously attributed as either Claytonia tuberosa [1] [2] (Inuit: oatkuk [3]) or Hedysarum alpinum (Inuit: mashu [3]).
In March 2015, Krakauer co-authored a scientific analysis of the Hedysarum alpinum seeds McCandless ate. The report found relatively high levels of L-canavanine (an antimetabolite toxic to mammals) in the H. alpinum seeds and concluded "it is highly likely that the consumption of H. alpinum seeds contributed to the death of Chris McCandless."

The Chiefs clinched the No. 1 seed and a first-round bye before their Week 18 game in Denver, which Mahomes sat out with many of their best players. And that meant he was able to focus on the ...
The toxicity of canavanine may be enhanced under conditions of protein starvation, [1] and canavanine toxicity, resulting from consumption of Hedysarum alpinum seeds with a concentration of 1.2% canavanine weight/weight, has been implicated in the death of a malnourished Christopher McCandless. [2]
