Japanese-sunflower
Tithonia diversifolia
Tithonia diversifolia, a plant native to Mexico and parts of Central America, has not been traditionally used for medicinal purposes. Scientific studies have identified several bioactive compounds that suggest potential antidiabetic effects through various pharmacological mechanisms. The antimicrobial activity of Tithonia diversifolia, particularly the tagitinin C-rich extract, is well-documented with strong activity against certain bacteria and significant biofilm disruption. Additionally, its forage meal has been noted for high crude protein and mineral content but may reduce in vitro digestibility at higher inclusion levels when used in pig diets. Safety data indicates no major issues have been recorded for Tithonia diversifolia. There are currently no reported drug interactions associated with this plant.
