The plant contains chemicals that are toxic to animals including humans, but it has also been used as a medicine. All parts of the plant contain protoanemonin, which can cause severe skin and gastrointestinal irritation, bitter taste and burning in the mouth and throat, mouth ulcers, nausea, vomiting, diarrhea, and hematemesis.

A foxtail is a spikelet or cluster of a grass, that serves to disperse its seeds as a unit. Thus, the foxtail is a type of diaspore or plant dispersal unit. Some grasses that produce a foxtail are themselves called "foxtail", also "spear grass". They can become a health hazard for dogs, cats, and other domestic animals, [1] and a nuisance for ...
The GLVs responsible for the smell of freshly cut grass play a role in plant communication and plant defence against herbivory, functioning as a distress signal warning other plants of imminent danger and, in some instances, as a way to attract predators of grass-eating insects. For humans, the smell of freshly cut grass is connected through ...
Parthenin is a major toxic chemical in Parthenium hysterophorus. Contact with the plant causes dermatitis and respiratory malfunction in humans, and dermatitis in cattle and domestic animals. The main substance responsible is parthenin, which is dangerously toxic.
The administered poison must have a low toxicity so that it does not cause further damage to other animals or plants; a popular toxin that has worked well is Botulin toxin C. [10] As for highly degraded plots of land, planting semi-artificial grassland is the umbrella term that is used to address this type of restoration. [ 2 ]

The awns containing several seeds may tangle together and the mass is blown away from the parent plant on the wind. They also stick to animals, another vector of seed dispersal. [1] Hesperostipa spartea has a bunchgrass foliage mass of 3–6 feet (0.91–1.83 m) in diameter [4] The flower stalks are upright and arching, yellow, in late Spring. [4]
