After reading this post (and a quick tour around your blog, very nice!), I looked up and found out this root is also astringent and used for sore throats. I also have a lot of P. recta, sulphur cinquefoil, which is very pretty, not sure yet how to use that one. But guessing they all have similar properties. Thanks again for posting great content!
