Toxicity

Many Euphorbia species produce a milky sap or latex that is toxic and can cause skin irritation. Some species are highly toxic and can be fatal if ingested.

Species

There are over 2,000 species in the genus Euphorbia. Some of the most well-known include Euphorbia pulcherrima (poinsettia), Euphorbia milii (crown of thorns), and Euphorbia tirucalli (pencil tree).
