Extra fluid retention in the body usually results in a swelling condition called edema. It can affect any part of the body but mostly the arms, feet, ankles, and legs.
Edema can be caused by a variety of conventional medication, pregnancy or a number of underlying ailments such as heart problems, kidney disease or cirrhosis of the liver.
If edema is caused by underlying disease it needs to be addressed first if there is to be any reduction of water retention.
Medicinal herbs for edema treatment and relief mostly focus on addressing the causes of liquid retention in the body.
These medicinal herbs usually have diuretic properties which fight the factors that cause edema by reversing their effect and restoring the body’s fluid balance.
Diuretic herbs also strengthen deteriorating blood vessels and help the lymphatic system to move excess fluids from the body. They stimulate the kidneys and the urinary tract system in order to flush out excess water and body wastes resulting in less water retention in the body.
It is important to consult a professional health care provider about the use of medicinal herbs for edema prior to use, particularly for those on conventional medication or those who have a history of serious diseases.
Women who are pregnant or breastfeeding should only use herbs for therapeutic reasons under the guidance of a doctor.

The herb is thought to be helpful in reducing edema by eliminating water weight and increasing urination. It is also considered a mild laxative, which further boosts its effect as a natural diuretic.
In one study, the herb was shown to increase urination in humans when it was administered in extract form, indicating that its traditional uses for water retention have some scientific basis. The study was first published in August 2009 in the “Journal of Alternative and Complementary Medicine.
Still, more and thorough studies are needed to fully confirm the herb’s efficiency as a viable alternative to conventional diuretic medication.

A research study from the year 1992 conducted at the Kinki University in Japan showed that the leaves of the plant contain a substance know as arbutin.
Arbutin has been proven to reduce swelling especially when combined with indomethacin, a nonsteroidal anti-inflammatory medication (NSAID) that reduces fever, pain, and inflammation.
