Background

Mountain ash is a tree. People use the berries and flowers to make medicine. The berries may be used fresh, dried, or cooked and then dried.

People take mountain ash for diabetes, diarrhea, gout, heart disease, and many other conditions, but there is no good scientific research to support any of these uses. Eating large amounts of fresh mountain ash berries can also be unsafe.

In manufacturing, mountain ash is used as an ingredient in marmalade, stewed fruit, juice, liqueur, vinegar, and in tea mixtures.
When taken by mouth: Fresh mountain ash berries are POSSIBLY UNSAFE. Eating large amounts can cause stomach irritation and pain, vomiting, queasiness, diarrhea, kidney damage, and other side effects. There isn't enough reliable information to know if dried or cooked mountain ash berries are safe or what the side effects might be.

Special Precautions & Warnings:

Pregnancy and breast-feeding: It's POSSIBLY UNSAFE to use large amounts of fresh mountain ash berries. Not enough is known about the safety of dried or cooked berries. Stay on the safe side and avoid using any mountain ash product.

Kidney disease: There is a chemical in mountain ash berries that might harm the kidneys. If you have kidney disease, don't risk making it worse by taking mountain ash berries.
