[1] It is found for instance in Geranium thunbergii, which is one of the most popular folk medicines and also an official antidiarrheic drug in Japan.

[3] It mediates apoptosis by cleavage of focal adhesion kinase through up-regulation of Fas ligand expression in human melanoma cells.

[1] Geraniin has also been shown to possess immunomodularity properties, as it inhibits tumor necrosis factor-alpha, and NF-κB in ovarian cancer cells.

[4] Geraniin was studied for its anticancer activity and shown to target apoptosis via inactivation of PI3K/Akt/mTOR signaling pathway involving NF-κB when treated against HT-29 human colorectal adenocarcinoma cells.

[citation needed] Chebulagic acid is formed from geraniin through a glutathione-mediated conversion.
