What Is Hawthorn?

Hawthorn is a type of Crataegus plant that belongs to the rose family. Hawthorn is a thorny shrub that often blooms with white or pink flowers. The leaves, flowers, and berries have been used medicinally in traditional Chinese medicine.

The beneficial ingredient in Hawthorn is a flavonoid. A flavonoid is a plant chemical that is responsible for the bright coloration of many fruits and vegetables. Instead of being digested, flavonoids are utilized by bacteria in the gastrointestinal tract and result in anti-inflammatory and antioxidant benefits. It is important to note that there are different types of flavonoids, and each flavonoid can offer different benefits.

Although used for a variety of benefits in humans, hawthorn is generally administered to dogs with cardiac problems. As mentioned in an article by the VCA,1 little research has been done looking at the specific benefits of hawthorn in dogs. However, human studies have shown that hawthorn can benefit blood pressure and improve exercise tolerance and digestive concerns.

How Is Hawthorn Given?

Hawthorn is given orally and is available as a pill, capsule, or liquid. Additionally, the plant leaves and berries can be dried as well.

Hawthorn can be given with or without food. However, if hawthorn causes gastrointestinal upset when given on an empty stomach, it should be administered with food. Be sure to check the individual product packaging for instructions on how best to store hawthorn.

What Happens if You Miss a Dose?

If you miss a dose of hawthorn, you can give it when it is remembered and then continue with the normal dosing schedule. However, if it is close to the next time it is due, skip the missed dose. Do not double up on doses.

Potential Side Effects of Hawthorn

Safe use in dogs with concurrent conditions like kidney and liver disease has not been established. This is also the case for pregnant and nursing animals. The VCA also notes that hawthorn use should be avoided in animals with low blood pressure and low heart rates.

  • Barbiturates
  • Blood pressure medication
  • Anticoagulants
  • Caffeine
  • Epinephrine
