Plantain, Rib Grass: Plantago major/lanceolata
Plantain is one of my herb teacher, Michael Vertolli's, favorite healing herbs for epithelia, skin and mucus membranes, for as he describes, it is a wonderful mild balance of vulnerary (healing), demulcent (stimulating health mucus), and astringent (binding/tightening).
It is useful on its own, or in combination, for all internal epithelia, gut, urinary, lungs, etc. And it can be used as a poultice externally. Or just mash it up between your hands and put the juice on wounds (where you don't fear for infection).
more to come, but I want to post this start for now.
