It turns out that you don’t have to be a Vulcan like Spock or Tuvok to have green blood.
No, you merely need to have migraines.
A team of Canadian surgeons discovered during an operation that their patient had dark green blood. Why? Because of the migraine medication he was on, sumatriptan.
The result?
This had caused a rare condition called sulfhaemoglobinaemia, where sulphur is incorporated into the oxygen-carrying compound haemoglobin in red blood cells.
Describing the case in the Lancet, the doctors, led by Dr Alana Flexman from St Paul’s Hospital, Vancouver, wrote: “The patient recovered uneventfully, and stopped taking sumatriptan after discharge.
“When seen five weeks after his last dose, he was found to have no sulfhaemoglobin in his blood.”
Green blood.
The world is a weird damn place sometimes.
