Toxicity of Green milkweed

Is Green milkweed toxic to humans?

Green milkweed is a toxic species that poses risks when consumed, primarily due to its cardiac glycoside content. These harmful substances can disrupt heart rhythms, leading to potentially severe outcomes, especially if significant quantities of green milkweed are ingested. The severity of symptoms varies depending on the age, weight, personal sensitivity, and overall health of the individual consuming it. Young children are particularly vulnerable to adverse effects, as they tend to be the most inquisitive and have lower body weight. Additionally, direct contact with the sap of green milkweed may result in dermatitis, which can cause the affected area to redden, itch, become inflamed, or develop blisters.
