Does Dandelion Work?

Dandelion is a common weed; it grows abundantly in temperate climates throughout the world. Herbalists have used the leaves, roots and flowers of the dandelion plant for thousands of years, as a treatment for dozens of common conditions. If you are interested in using dandelion as a botanical medicine, you may find yourself wondering, "Does dandelion work?"

The answer to this simple can range from a resounding "yes" to an equally assured "no," depending on your use for the herb. Dandelion does work in some capacities, but it is ineffective in others. Here is a summary of the proven, disproven and under-researched effects of dandelion.

What Dandelion Works For

Dandelion is effective as a diuretic and as a source of potassium. Diuretics such as dandelion help to flush excess fluids from the body by increasing the rate at which a person urinates. This can help to relieve bloating and water retention associated with hormonal fluctuations and certain medical conditions. Unlike prescriptiond diuretics, dandelion contains potassium, an electrolyte which, along with sodium, helps to regulate fluid balance.

What Dandelion Might Work For

According to theory, tradition, and limited scientific studies, dandelion may help to treat urinary tract infections, kidney disease, intestinal gas, anorexia, constipation, arthritis and upset stomach. Although many traditional herbalists believe that dandelion is effective in these capacities, there is not enough tangible scientific evidence to confirm or refute these claims. Fortunately, dandelion is generally a low-risk supplement, so it's unlikely to cause serious side effects if you try it out short-term to see if it benefits you.

What Dandelion Doesn't Work For

Several of dandelion's uses are disproven or scientifically implausible. Although some people use dandelion to treat viral infections such as colds and flu, there is no evidence that it works in this capacity. Dandelion's use as a "blood purifier" is also somewhat implausible, and, although it may improve digestion and appetite in cancer patients, there is no reason to believe that it treats or cures cancer.
