Robert’s Herb or Herb Robert cranesbill, Geranium robertianum L., and wild or spotted cranesbill, G. maculatum L. [Fam. Geraniaceae], are perennial wild flowers native to Europe and North America. Herb Robert is a popular folk remedy against abnormal growths recommended by a Russian doctor as part of a ‘Breuss Cure’. The leaf tea was also used against malaria, tuberculosis and digestive disorders. Additionally, Herb Robert leaf tea was used similarly to the more widely used tannin-rich roots (10-28%) of wild or spotted geranium that are highly astringent. Cranesbill tea was traditionally used as a styptic to stop bleeding and also to treat diarrhea, dysentry, relieve piles and gum disease and act as a diuretic. Wild geranium root tea was used as a tonic in folk medicine and was additionally used to treat burns, abnormal growths, cholera, gingivitis, hemorrhoids, leucorrhea, infections (including the plague), internal bleeding, canker sores, wounds, toothache, sore mouth and throat, ulcers, and various stomach problems. Cranesbill is particularly suitable for treating diarrhea in children and is reputedly devoid of unpleasant side effects. The astringent tannins of Herb Robert and wild cranesbill tea directly improve the tone and function of mucous membranes and the tea may be ingested or used externally. A cranesbill poultice was specifically recommended to relieve the pain of swollen breasts. The English took cranesbill for hemorrhages, jaundice, and urinary system infections. Cranesbill is more popular in Europe than in North America. Geranium maculatum is also popularly used by Peruvian people in different locations of Peru for the treatment of diarrhea, with good success. Based on an “in vitro” study, Geranium maculatum showed no bactericidal effect to stop cholera spreading. Nevada tribes used cranesbill tea as a method of birth control, and it was believed that the user would not become pregnant for a year.
