Some options to cleanse the kidneys include herbal supplements, eating certain foods and taking vitamins, according to About.com. It is also important to drink a lot of water, stay at a healthy weight and avoid smoking, to encourage the kidneys to cleanse themselves.
Many people use herbal supplements to cleanse the kidneys, such as dandelion, juniper, marshmallow root, parsley and nettles, explains About.com. Ginger, red clover and goldenrod also help to cleanse the kidneys. Diet is important when cleansing the kidneys, and food such as lemon juice, watermelon, pumpkin seeds and cranberry juice are good to ingest. Vitamins such as magnesium and vitamins B6 and B2 are also taken to cleanse the kidneys.
Kidney cleanses may help to keep blood pressure under control, improve urinary tract function, clear toxins from the body and boost immunity, states About.com. Although the individual components of a kidney cleanse may offer benefits to those who use them, there is no evidence that these cleanses help to prevent kidney stones, as of 2015. There are foods, however, that may help to reduce the instance of kidney stones, such as okra, chocolate, sesame seeds, sweet potatoes and spinach. It can also help if individuals cut back on sodium intake and drink more water.
