No, Jackson Galaxy Solutions will not interfere with any medications, including the anaesthesia used for surgery or dental cleaning. Dr Jean Hofve, leading holistic veterinarian and co-creator of Jackson Galaxy Solutions says, “because essences work on an energetic rather than physical level, they do not interfere with medical treatments like drugs and surgery; or with alternative therapies such as homoeopathy, acupuncture, or herbs; or any other therapy that affects the physical body.” Please consult with your veterinarian should you have any questions.
