Toxic to pets and people

Crown of Thorns can cause irritation or illness if chewed or swallowed. Keep it out of reach of pets and small children.

Irritant: Diterpene esters in milky latex
Severity: mild
Symptoms: The milky white latex sap found in all plant parts can cause mild to severe contact dermatitis. If contact with the eyes occurs the sap can cause temporary to permanent damage to the cornea.

The Full Picture

The Crown of Thorns is technically a succulent, not a true cactus. It wants more water than a standard cactus, but much less than a regular houseplant. If it gets too dry, it will drop all its leaves to conserve water—but don't throw it out! Once you resume watering, it will grow them all back. Be extremely careful when pruning: it bleeds a thick, white latex sap that is highly toxic and irritating to the skin and eyes.
