All plants in the genus Asclepias are probably somewhat toxic, some fatally so, to both humans and other animals. The sap of some, including Asclepias oenotheroides, causes skin irritation in humans. The word zizotes in this plants common name is a Spanish term meaning skin sores. Sensitivity to a toxin varies with a person’s age, weight, physical condition, and individual susceptibility. Children are most vulnerable because of their curiosity and small size. Toxicity can vary in a plant according to season, the plant’s different parts, and its stage of growth; and plants can absorb toxic substances, such as herbicides, pesticides, and pollutants from the water, air, and soil.
