How does Gentian work?
Gentian contains a chemical that might dilate blood vessels.
Are there safety concerns?
Gentian seems to be safe for most people when used in small amounts as part of a combination product containing gentian root, elderflower, verbena, and cowslip flower (SinuComp, Sinupret). There isn't enough information to know if gentian is safe when used in medicinal amounts other than as part of the combination product. The combination product can cause digestive system upset and occasionally allergic skin rash
The highly toxic white hellebore (Veratrum album) can be mistaken for gentian and has caused accidental poisoning when used in home-made preparations.
Do not take gentian if:
- You are pregnant or breast-feeding.
- You have low blood pressure.
- You are scheduled for surgery in the next two weeks.
