Yes all parts of the plant can be used for something all the way to the roots for making( non thc/very low) tinctures or tea,a general Google search will yield endless links,or you can stop by our very own Farmacy for some great ideas..I saved everything from my first two grows hoping to make "something" out of "everything" ,it just turned into a hoard and went to the burn pile,,,good luck in your journey cause there are multiple uses for every part. When you do start making a variety of products don't forget to share them with us !!! Nowadays I just make the standard extracts,cannabutter,pain salves...Cheers
