Details: Toxicity:
Although a few species of Astragalus are used as forages or human medicines, many species are toxic. Two different types of neurotoxicity, locoism and "cracker-heels", are produced; a few species also accumulate toxic levels of selenium or cause other forms of toxicity. The toxic compounds responsible for locoism are present in highest concentration in the fruits and seeds (Burrows & Tyrl 2001).
