One thing you should bear in mind, whatever you do, is that the sap of Euphorbias can be pretty nasty. So if and when you decide to make a cut, be sure to wear gloves and avoid getting the sap on your skin, especially on your face. That way you can avoid a rash or potentially more serious problems. I have no experience with this particular plant, and it could be innocuous, but it's good to keep Euphorbias at a safe distance when in doubt.
