TL;DR: Inhibition of the fibroblast proliferation induced by prostatic growth factors and of the production of the chemotactic leukotrienes from human polymorphonuclear cells, as well as of the 5α-reductase and aromatase activities, seems to play a role in the clinical efficacy of the extract.

TL;DR: Results revealed that F. exasperata has a remarkable potential for the treatment of gastrointestinal diseases and significantly and dose-dependently protected rats from induced ulcers.
