There are many kidney cleanse programs available on the Internet and at local health food stores. Each will usually involve the use of herbs and drinking large amounts of water. A kidney cleanse is done in order to cleanse the delicate kidney tubules and supporting tissues from foreign substances which have collected there due to the body's inability to eliminate them. The kidneys are one of the major eliminative organs. They must be thoroughly cleansed in order to prepare the body for any eliminative crisis which might result when further demands are placed upon them due to cleansing taking place elsewhere in the body, or detoxifying treatments being employed,
.
The following herbs are often found in kidney cleanse programs:
hydrangea root (Hydrangea arborescens), gravel root (Eupatorium purpureum), marshmallow root (Althaea officinalis), cleaver’s herb (Galium aparine), golden rod (Solidago virgaurea), fresh parsley (Petroselinum sativum), uva ursi leaves (Arctostaphylos Uva-Ursi), ginger (Zingiber officinale) and juniper berries. Other traditional kidney herbs are: shave grass, cedar berries, butcher's broom and cornsilk.

A kidney cleanse should be done twice a year if possible. They are typically several weeks in duration or longer.
Elderly persons, those suffering from the eliminative process of cancer and special cases should do only half of a kidney cleansing regimen. This would be:
1) 1/2 dosage of kidney herbs for first five days
2) Full dosage for two weeks
3) Half dosage for three months.
