Elderflower

Background

Elderflower is the flower of the elder tree. An extract of the flower is used to make medicine.

Elderflower is used for common cold, flu (influenza), swelling (inflammation) of the nasal cavity and sinuses (rhinosinusitis), and many other conditions, but there is no good scientific evidence to support these uses.

In foods and beverages, elderflower is used as a flavoring component.

In manufacturing, elderflower extracts are used in perfumes.
When taken by mouth: Elderflower is LIKELY SAFE when used in amounts found in foods. Elderflower is POSSIBLY SAFE for most people when used short-term as medicine, or in small amounts as part of a combination product containing elderflower, sorrel, gentian root, verbena, and cowslip flower (SinuComp, Sinupret). The combination product can cause digestive system upset and sometimes allergic skin rash.

Elderflower is POSSIBLY UNSAFE when used in excessive amounts. Some parts of the elder tree contain a cyanide-producing chemical which can cause nausea, vomiting, and diarrhea. Cooking removes this chemical.

Special Precautions & Warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if elderflower is safe to use when pregnant or breast-feeding. Stay on the safe side and avoid use.

Diabetes: There is a concern that elderflower might lower blood sugar levels. If taken with diabetes medications, it might make blood sugar levels go too low. If you have diabetes and use elderflower, be sure to monitor your blood sugar levels carefully.

Surgery: Elderflower might lower blood sugar levels. There is some concern that it might interfere with blood sugar control during and after surgery. Stop using elderflower at least 2 weeks before a scheduled surgery.
