Used to be known as Erigeron Canadensis. It has a somewhat hot taste like black pepper. I like the taste but I think it is better to use as a spice. Many use it in place of tarragon. I do not know what tarragon taste like so cannot comment on that. I used to grow it now I try and manage it. It does not take much for it to get away from you and overtake things. Some call it Horseweed, some call it mares tail. Is resistant to glyphosate so be careful where you forage it.
It helps fight cancer and reduces oxidative stress.
Phytochemicals, wow has some good ones.
Has anti-inflammatory effects, possibly by upregulating heme oxygenase-1 expression.
Prevents blood clotting.
Fights parasites and fungus.
Seems it may help with adrenal fatigue.
Reduces oxidative stress, and decreases CO2 generation in platelets.
