Patient Bleeds Dark Green Blood, is Not Vulcan
According to medical journal The Lancet, some doctors got quite a shock while they were operating; a patient started bleeding dark green blood. A little investigation turned out the fact that he was taking 200mg of sumatriptan (migraine medication) per day. This caused sulfhaemoglobinaemia, a condition in which sulfur becomes incorporated into the hemoglobin in your blood cells.
He made a full recovery after the surgery. He has since stopped taking the medication, after which, the condition disappeared in about 5 weeks.
