Forsythia

Background

Forsythia is a shrub. The dried fruit is used for medicine.

Forsythia is used for airway illnesses, swelling, fever, and other conditions. But there is no good scientific research to support any use.
When taken by mouth: There isn't enough reliable information available to know if forsythia is safe or what the side effects might be.

When given by IV: There isn't enough reliable information available to know if forsythia is safe or what the side effects might be.

Special Precautions & Warnings:

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

Surgery: Because forsythia might slow blood clotting, there is a concern that it might cause extra bleeding during and after surgery. Stop taking forsythia at least two weeks before a scheduled surgery.
