menyanthes trifoliata uses

The leaves of the buckbean plant contain a bitter glycoside (menyanthin), which gives the plant its stimulating properties on the digestive system. It increases appetite, stimulates digestive secretions, and as a rule, promotes digestion. It is recommended for digestive atony, bloated stomach, or chronic gastritis. It has similar effects to those of the gentian plant.

Buckbean also contains flavonic substances and alkaloids, which have not been well studied yet. These substances could explain its febrifuge, laxative, and emmenagogue properties. The plant is also used for influenza.

WARNING! When taken in high doses, it is purgative and an emetic (provokes vomiting).
