Edible Uses
Edible Parts: Leaves;  Oil;  Root;  Stem.
Edible Uses: Curdling agent;  Oil.

Root of first year plants - raw or cooked[183]. Nutritious but rather bland, they are best used in a mixture with other vegetables[9]. The root is likely to be rich in inulin, a starch that cannot be digested by humans. This starch thus passes straight through the digestive system and, in some people, ferments to produce flatulence[K]. Stems - they are peeled and cooked like asparagus or rhubarb[9, 12, 177, 183]. Leaves - raw or cooked[177, 183]. A fairly bland flavour, but the prickles need to be removed before the leaves can be eaten - not only is this rather fiddly but very little edible leaf remains[K]. The leaves are also used to coagulate plant milks etc[46, 61, 183].

The plant contains a volatile alkaloid and a glycoside called cnicin, which has emetic and emmenagogue properties[240]. The leaves are antiphlogistic[207]. They cause inflammation and have irritating properties[207[.

Re: eating the leaves of Cirsium arvense and C. vulgare: I pick these in quantity when the plant is under 1 foot/.3 meters high, then rinse them to remove dirt and bugs. I find that rinsing (at least under a stream of water) tends to disable the prickers to a noticeable extent. I cut the plant's stem with scissors via gloved hands, but rinse the leaves with bare hands. Then I cook them in water or stock (the latter is tastier) and the prickers are fully disabled. I then puree the leaves with a good quantity of milk (or milk substitute), season to taste with onion, garlic, salt, etc. and have a cream soup. I also put it in quiche or savory pancakes. I tell my friends I'm serving them something special, but don't say what until after they have tasted it and have exclaimed how good it is. You do NOT have to remove the prickers by hand from the raw plant, so it is not a fiddly process. It's a great green vegetable source. I hope you can include this on your American website as well, so people can stop being afraid of eating the leaves of this plant when it is young. Thank you for an excellent website. I live in CO, USA
