Absolutely .... I've never met anyone outside of the northern communities who knew about it.
In our language we call it 'KA-KEE-KEH-POO-KWA' .... I think the word stems from the word 'KA-KEE-KEH', which translates as 'forever' ... because you can even find this plant frozen in the wilderness in the dead of winter and still make tea from it.
However, it makes a very weak mild tea ... highly nutritious but it doesn't taste like much. I got the bright idea one summer to make it extra strong and boiled a small bushel to make a dark tea. A more scientific friend of mine later warned me that the drink has to be mild because in stronger doses, it can be poisonous.
