Title: Osage orange thorn in foot in Redford MO
Answered by: Barbara Medford
We are always amazed when our correspondents contact us before they see a doctor in situations like this. If there were toxin in the thorn, you would already know about it. We could find no indications that Maclura pomifera (osage orange) has any poisonous parts, including the thorns. However, any injury like that is susceptible to infection, which could be very serious. Or a piece of the thorn could still be in your foot, which also is dangerous. We have two suggestions: (1) see a doctor and (2) wear shoes when you go outside.
