Gentian lutea is a plant with yellow flowers that grows in Europe. The root has been used to treat digestive problems and lack of energy. It has also been used to make medicine, foods, and drinks. It can be taken as a pill, powder, extract, or made into a tea. It can also be applied to the skin.
There are no advised doses for gentian.
There is not enough data to support that gentian is helpful in treating health problems. We will review future studies as they are published.
Editorial process and description of evidence categories can be found at EBSCO NAT Editorial Process.
It may be safe to take gentian orally or use gentian on the skin for a short time. Not enough studies have been done to say whether it is safe to use for a long period.
Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse.
