A lot of these astralagus species accumulate high levels of toxic selenium from the soil. Other locoweeds produce the poisonous alkaloid swainsonine, although sometimes this alkaloid is produced by fungi living inside the plants, rather than the plants themselves. selenium hyperaccumulation makes the genus useful in plant-based prospecting, a technique which utilizes plant populations to find interesting mineral deposits. This can be accomplished just by trying to find the existence of ‘sign plants’, consisting of particular astragalus types, or by taking samples of plant material and performing chemical analyses for selenium.
