Why do some Yarrah products contain devil’s claw?

We use organic devil's claw from Albania, Croatia, France and Poland in our senior dog food. Devil's claw contains gluco-iridoids. These have anti-inflammatory, analgesic, sedative and diuretic properties. Perfect for the older dog. After all, it's good for detoxification and the suppleness of joints as well as reducing joint pain. Devil’s claw has a relaxing effect on the muscles. Furthermore, it encourages the excretion of waste and can help remedy poor appetite and digestive problems.
