When a herb’s medicinal traditions go back hundreds of years, there’s a good reason for its popularity. St John’s Wort’s history goes back to 400 BC and its therapeutic uses can help your dog as well.

What Is St John’s Wort?

St John’s Wort is a herb that grows in fields, along river banks, ocean shores and anywhere there’s poor soil. It got its name because it blooms around June 24th, the Feast Day of St John the Baptist. And it has some wide-ranging therapeutic properties.

The Ancient Greeks and Romans used St John’s Wort medicinally for anything from snake bites and digestive issues to depression and wound healing. In the Middle Ages its magical powers helped ward off evil and protect against disease. And you could predict your longevity by hanging a sprig of the plant near your bed overnight. If it withered, your chances for a long life were not good.

Today, it’s most famous as a natural substitute for Prozac in treating depression.

St John’s Wort Side Effects

People have used St John’s Wort safely for over 2,000 years. And even though it’s a natural herbal remedy, you should use it with caution and be aware of how it can influence other treatments.

Pharmaceuticals
St John’s Wort can interact with several types of pharmaceuticals. That’s because St. John’s Wort can cause the body to produce a type of enzyme that clears chemicals quickly from the bloodstream. So if your dog is taking meds, St. John’s Wort could lessen their effect. It can also react with common pharmaceuticals, and heart and anxiety medications.

Before using St. John’s Wort, be sure to check with your veterinarian or herbalist about any contraindications. Make sure that you tell them your dog’s medical history or if he’s on any current meds.

Diabetic Dogs
If your dog takes medication for diabetes, ask your vet before using St John’s Wort. The herb can be helpful in lowering blood glucose levels, but it could mean you need to reduce your dog’s dose of insulin or other medications to avoid triggering dangerously low blood glucose.

Avoid Before Surgery
Don’t give St John’s Wort for 48 hours before surgery as it may strengthen the effects of anesthesia.

Other Cautions
In rare cases, some animals can develop a photosensitive rash (similar to sunburn) from St John’s Wort. Use extra caution if your dog is white, has white or pink skin pigment or a short coat. If a rash develops, keep your dog out of sunlight and discontinue use.

As you can see, St John’s Wort isn’t just for depression or anxiety. Give some of these uses a try for your dog.
