The common Scullcap (Scutellaria galericulata) is a herb and can be found all around the northern hemisphere shorelines. Found these on a small island. It is still used for medicinal purposes but as there are many various species you need to leave it for the experts. In other words, don’t try this at home.
In Swedish it is called “Frossört” and the name probably comes from its medicinal use to reduce fever. “Frossa” is the Swedish word for fever chill.
I’m a bit tempted to test as I sit here with a slight fever from the second Covi-19 vaccine shot. Ha de Gött!
