Is it safe to use herbal supplements if I have kidney disease? No. You may think about using herbal supplements to help with any health concerns you may have, but as a patient with kidney disease, you should not use herbal supplements. Use of herbal supplements is unsafe if you have kidney disease since some herbal products can cause harm to your kidneys and even make your kidney disease worse. Also, your kidneys cannot clear waste products that can build up in your body.
