I have a lot of Echinacea, or Purple Cone Flowers. They were here when I moved in and they grow wild here in abundance. I don't think they were planted by anyone, anyway, they're real good for a headache. I make a tea from the petals. They don't taste bad, but, they don't taste great, so I throw in a regular teabag and then they just taste like tea. Echinacea has a relaxing quality, on me anyway. It's a good antibiotic too and it's the only thing I've found that works on dry socket after a bad dental visit. I can drink a lot of it, but, you can start with a few petals and see how you like it. It sure won't hurt you and it's easy to identify. It's also used to relieve urinary tract infections. You can dry it, but, you don't have to.
