You are supposed to wait until the fall to make dandelion tincture. You dig up the roots and wash them. If you have had a couple of frosts, you can use the greens in a sauté, but if they will be terribly bitter if you haven't had a frost yet.
Cut up the root into small pieces and place in 90 proof (or better) alcohol for two weeks. You should shake it every day, then strain it and place it in dark glass bottles.
My root is still curing. But I'm curious to see how it turns out. As always, if you try making something like this, be absolutely sure you know the plant is dandelion, and talk with your doctor before using.
I'll let you know how it goes! Readers, do you use any sorts of herbal remedies? I want to try making dandelion coffee next.
