petty spurge, Euphorbia peplus

If only I had known sooner! This insignificant weed has white sap. If you get some on your fingers and forget it, and later rub your eyes, you will never again think of it as insignificant. You might start calling it by its other name, radium weed. On the other hand that sap is genuinely effective for treating actinic keratosis and skin cancer. If I had known all this I could have saves a lot of trips to treatment! No eye flushing! No liquid nitrogen! Most of all no scalpels? Or maybe just not mess with it. If it gets in your garden, be careful. And wear hats! Petty spurge has been reported from every state and province except AR, FL, KS, KY, MN, MO, MS, NE, OK, SC, SD, TX, WY, LB, NT, NU, YT, and is on SPM. Lenawee Co MI, 7/5/18. Spurge family, Euphorbiaceae.
