Overview

Overview Information

Ash is a tree. The seeds are used to make medicine.

People use ash for diabetes, arthritis, constipation, bladder problems, and many other conditions, but there is no good scientific evidence to support these uses.

Don't confuse ash with manna ash, northern prickly ash, or southern prickly ash.

How does it work?

Certain chemicals in ash might help to lower blood sugar.

Uses

Uses & Effectiveness?

Insufficient Evidence for

  • Obesity. Taking ash extract doesn't seem to boost weight loss or improve blood sugar control in people who are already dieting. But it might help reduce fat by a small amount.
  • Fever.
  • Arthritis.
  • Bladder problems.
  • Constipation.
  • Increasing urine production to relieve water retention (as a diuretic).
  • Other conditions.
More evidence is needed to rate the effectiveness of ash for these uses.

Side Effects

Side Effects & Safety

When taken by mouth: Taking ash seed/fruit extract is POSSIBLY SAFE when used in doses of up to 1 gram daily for up to 3 months. No side effects have been reported in clinical research. But some people might be allergic to ash.

Special Precautions & Warnings:

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

Cross-allergies: Some people are allergic to chemicals in the pollen in ash. Since similar chemicals are found in other pollens, people allergic to other pollens might also be allergic to ash pollen.

Diabetes: Ash might affect blood sugar levels. Watch for signs of low blood sugar (hypoglycemia) and monitor your blood sugar carefully if you have diabetes and use ash.

Keep in mind that natural products are not always necessarily safe and dosages can be important.
