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.

Natural Medicines rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.

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

When taken by mouth: There isn't enough reliable information to know if quince fruit is safe for medicinal use. The seeds contain cyanide, which suggests that quince seeds might not be safe.

Medications taken by mouth (Oral drugs)

Interaction Rating=Major Do not take this combination.

Quince contains a type of soft fiber called mucilage. Mucilage can decrease how much medicine the body absorbs.

To prevent this interaction take quince at least one hour after medications you take by mouth.

There are no known interactions with herbs and supplements.
