The herb St. Johns Wort is perfectly safe for your dog when used properly as it is in our Nerve Tonic remedy. St. Johns Wort receives some hype online due to a few factors. In studies, when taken in very large amounts, which one would never consume outside a laboratory setting, or used in topical creams (which dogs and cats don't use) St. Johns Wort can cause photosensitization when exposed to strong UV light. St. Johns Wort can also cause the liver to more quickly detoxify medications, so Nerve Tonic should be given at least two hours away from any medications being given to a cat or dog. Lastly, St. Johns Wort is often recommended as an antidepressant because it can increase serotonin in the brain. As a result this herb shouldn't be used with any antidepressant or anti-seizure medications. Neurological symptoms in a dog with cushings are caused be excessive levels of cortisol. Our Nerve Tonic was a good choice, however I would rather have you try our Cushings Support Package and the Flaxseed Lignans to help support healthy levels of cortisol and see if that resolves your dog's neurological complaints.
