About

Stevia (Stevia rebaudiana) is a bushy shrub that is native to northeast Paraguay, Brazil and Argentina. It is now grown in other parts of the world, including Canada and part of Asia and Europe. It is probably best known as a source of natural sweeteners.

Some people take stevia by mouth for medical purposes such as lowering blood pressure, treating diabetes, heartburn, high uric acid levels in the blood, for weight loss, to stimulate the heart rate, and for water retention.

Extracts from the stevia leaves are available as sweeteners in Japan, South Korea, Malaysia, Taiwan, Russia, Israel, Mexico, Paraguay, Uruguay, Venezuela, Colombia, Brazil, and Argentina. In the US, stevia leaves and extract are not approved for use as a sweetener, but they can be used as a "dietary supplement" or in skin care products. In December 2008, the U.S. Food and Drug Administration (FDA) granted Generally Recognized as Safe (GRAS) status to rebaudioside A, one of the chemicals in stevia, to be used as a food additive sweetener.

How does it work?

Dosage

The appropriate dose of stevia depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for stevia. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.

Possible Side Effects

Stevia and chemicals contained in stevia, including stevioside and rebaudioside A, are when taken by mouth as a sweetener in foods. Rebaudioside A has generally recognized as safe (GRAS) status in the U.S. for use as a sweetener for foods. Stevioside has been safely used in research in doses of up to 1500 mg daily for 2 years.

Some people who take stevia or stevioside can experience bloating or nausea. Other people have reported feelings of dizziness, muscle pain, and numbness

Special Precautions & Warnings

Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking stevia if you are pregnant or breast feeding. Stay on the safe side and avoid use.

Allergy to ragweed and related plants: Stevia is in the Asteraceae/Compositae plant family. This family includes ragweed, chrysanthemums, marigolds, daisies, and many other plants. In theory, people who are sensitive to ragweed and related plants may also be sensitive to stevia.

Diabetes: Some developing research suggests that some of the chemicals contained in stevia might lower blood sugar levels and could interfere with blood sugar control. However, other research disagrees. If you have diabetes and take stevia or any of the sweeteners it contains, monitor your blood sugar closely and report your findings to your healthcare provider.

Low blood pressure: There is some evidence, though not conclusive, that some of the chemicals in stevia can lower blood pressure. There is a concern that these chemicals might cause blood pressure to drop too low in people who have low blood pressure. Get your healthcare provider's advice before taking stevia or the sweeteners it contains, if you have low blood pressure.
