An antidiuretic is a substance that helps the body retain water. It prevents the kidneys and bladder from removing and eliminating water from the body too quickly. Antidiuretic medicines are used to treat bed-wetting, incontinence and similar conditions. Some herbs have natural antidiuretic properties. When adding any herbal supplement to your diet, however, remember to first check with your doctor to ensure the supplement will not interfere with your other medications or conditions and that the symptoms for which you are taking the supplement do not require further medical intervention.
Licorice, also known as sweet licorice, has antidiuretic properties, according to the Indian Medicinal Plants Growers' Consortium. Licorice roots may be brewed in tea, or licorice candies may be eaten, as long as the candies contain actual licorice and not merely a licorice-like flavoring. People with high blood pressure, stomach ulcers, or who are taking medication derived from digitalis should not use licorice.
Yohimbe is typically used as an extract from the bark of the yohimbe tree, according to Vitamin Diary. It is used as an antidiuretic as well as a treatment for impotence. Use 15 to 30 mg of yohimbe extract per day under medical supervision. Patients who are taking antidepressants, nervous system stimulants, clonidine or blood pressure medication should avoid using yohimbe except under a doctor's close supervision.
Valerian is popularly used to treat insomnia, but is also effective as an antidiuretic, according to the Wild Rose College and Wholistic Clinic. Since patients can develop a tolerance to valerian when using it over time, the Wild Rose College recommends using valerian for only one month continuously. Valerian can be used now and then as an antidiuretic as well. The recommended dose is 250 to 750 mg two or three times daily, usually before bed. Patients with a history of depression, including bipolar disorder, should consult a physician before taking valerian.
