Uva ursi, parsley capsules, juniper berries and bucha leaves are common herbal remedies purported to effectively prevent the accumulation of toxic materials in the body by acting as diuretics. However, these herbal supplements may have adverse side effects, states the United States' National Kidney Foundation.
Herbal remedies are a group of botanically-derived products commonly used in traditional medicine, according to MedicineNet. These supplements are not monitored by the U.S. Food and Drug Administration and may contain certain ingredients, such as phosphorus and potassium. These particular minerals are detrimental to people diagnosed with a kidney disease.
Other herbal remedies may also cause dangerous drug interactions with prescription medications. These herbs include ginkgo, ginseng, garlic, blue cohosh and St. John's Wort. Patients with renal problems are strongly recommended not to use any herbal remedy, suggests the National Kidney Foundation.
