Herb Robert (Geranium robertianum) is a traditional medicinal herb used in various folk medicine systems. Its use for anxiety is rooted primarily in herbal tradition rather than scientific validation. Historically, Herb Robert has been employed as a general tonic and for a range of ailments including digestive issues, wounds, and infections. Some herbalists have recommended it for its purported calming or adaptogenic effects, but there is minimal documentation in historical texts specifically linking it to anxiety treatment. The plant contains compounds such as tannins, flavonoids, and geraniin, which have general antioxidant and anti-inflammatory properties, but there is no robust evidence that these constituents directly impact anxiety pathways.

A search of modern scientific literature reveals no clinical studies or preclinical animal research specifically evaluating Herb Robert for anxiety or related mood disorders. It is not listed in major herbal pharmacopeias or guides as a primary or even secondary remedy for anxiety. Therefore, any use of Herb Robert for anxiety rests almost entirely on anecdotal or traditional usage, without scientific substantiation.

In summary, while Herb Robert has a long history in folk medicine, its use for anxiety is limited to traditional claims. There is a lack of scientific evidence or formal recognition for this indication, and the overall evidence rating is low.
