Bloody Cranesbill



COMMON NAME  : Bloody cranesbill

FAMILY  :        Geraniaceae  (Geranium family)


Popular garden plant related to American cranesbill (G. maculatum) and Herb Robert (G. robertianum). G. robertianum is a native UK species, G. maculatum is  the wild US species used by American Indians.

PARTS USED  :        dried rhizome, leaves


G. sanguineum does not appear to be traditional in UK but elsewhere in Europe e.g. Bulgaria it is also used as an astringent for diarrhoea and dysentery and has been investigated for anti-viral (herpes, influenza) activity.

American cranesbill, G. maculatum, is the one covered by Grieve and Bartram as styptic, astringent, antiseptic and tonic for haemorrhoids, diarrhoea, dysentery, internal bleeding, heavy periods and vaginal discharge. Used now to treat diarrhoea, IBS (irritable bowel syndrome) and internal bleeding and externally for prurulent wounds, haemorrhoids and vaginal discharges. It is also beneficial for urinary complaints including frequency and incontinence in young and old. Herb Robert is used mainly for bleeding anywhere in the gastrointestinal tract from mouth ulcers to piles and for nosebleeds as well as irritable bowel but not seemingly for urinary problems.

CONSTITUENTS  :  Both noted mainly for tannins of poly-phenolic type.
