Overview

Overview Information

Quince is a small tree bearing a yellow fruit. The seed, fruit, and leaves are used as medicine.

Quince fruit syrup is sometimes used for persistent heartburn in children. Quince is also used for morning sickness, hay fever, stomach ulcers, and many other conditions, but there is no good scientific evidence to support these uses.

In foods, quince fruit is used to make jam, jelly, marmalade, and pudding. It is also used to make juice and wine.

Some chemicals in quince might reduce how the immune system responds to substances that cause allergic reactions.
