Wild Geranium is one of the plants students of the field botany program see a lot of.  Although it is common and thus commonly overlooked, it has a rich history of medicinal uses. The root is a superior astringent with tonic properties, and usually quite acceptable to the stomach.  It is not so intense as oak, but much stronger than rubus.  It is among the most useful agents of its class, not so suddenly drying the mucous membranes as some agents do.  It is employed for its astringent and tonic influence on mucous membranes in any sort of digestive condition involving a damaged or lax gastrointestinal tract.  It is famous for its use in diarrhea, both as a tea or tincture, but can also be used for any sort of ulcer, abrasion, or inflammation of the digestive tract to dry, draw, and shrink swollen tissues while promoting healing.
