I have my own holistic veterinary practice and I use the products in my patients. I am also paid by VETiONX to answer emails thru their website and occasionally help them with instructional videos. I believe they have a a return policy on the website or you may call customer service and discuss it. I don't get involved with the business side of things. Medicine is my interest.
Generally homeopathics have few side effects because it is an energy instruction to the body to make adjustments so homeostasis is achieved. There are few molecules of the original tincture left so it is unlikely for toxicity to develop. Please let us know if you have any other questions.
