Note: Do not confuse Stevia rebaudiana with Stevia salicifolia, also called ronion or roninowa. Stevia salicifolia contains the bitter glycoside stevisalioside.
Extracts of leaves from Stevia rebaudiana Bertoni have been used for many years in traditional treatment of diabetes in South America. Paraguay's rural and indigenous populations have used Stevia rebaudiana for the control of fertility.
Stevia rebaudiana standardized extracts are used as natural sweeteners or dietary supplements in different countries for their content of stevioside or rebaudioside A. These compounds possess up to 250 times the sweetness intensity of sucrose, and do not have any calories. Stevioside, a natural plant glycoside isolated from the plant Stevia rebaudiana, has been commercialized as a non-caloric sweetener in Japan for more than 20 years.
Stevia is not generally recognized as safe (GRAS) nor approved as food additives by the U.S. Food and Drug Administration (FDA). Stevia may be imported only if "explicitly labeled as a dietary supplement or for use as a dietary ingredient in a dietary supplement." Although stevia may be marketed as a dietary supplement or an ingredient of a dietary supplement under the Dietary Supplement Health and Education Act (DSHEA), products that are labeled as using stevia plant parts or extracts as flavoring agents, sweeteners, or for other food additive purposes are deemed as "unsafe." Regulatory agencies in Canada and Europe also have not approved use of stevia as a food additive. However, rebaudioside A (reb-A) is a steviol glycoside that is extracted from stevia and obtained FDA GRAS status as of December 2008.
Hypertension (high blood pressure):
Stevioside is a natural plant glycoside isolated from the plant Stevia rebaudiana, which has demonstrated blood pressure lowering effects. Despite evidence of benefits in some human studies and support from laboratory and animal studies, more research is warranted to compare stevia's effectiveness with the current standard of care and make a firm recommendation. Stevia appears to have no major side effects.
Stevia has been widely used for diabetes in South America and animal studies have had promising results. Studies report decreases in plasma glucose when stevia was taken in normal volunteers, but there is currently no conclusive evidence of effectiveness when used for diabetes. Additional study is needed in this area to confirm these findings.
For hyperglycemia (high blood sugar), 1 gram of stevioside has been taken with meals to lower blood sugar in patients with type 2 diabetes. Water extracts of 5 grams of leaves have also been used at regular six-hour intervals for three days to increase glucose tolerance.
For hypertension (high blood pressure), stevioside (250-500mg) capsules given three times daily decreased systolic and diastolic blood pressure after three months of therapy, and have been studied for up to two years. Despite early evidence that this may be an effective dose, a recent study did not find any benefit of crude stevosides (up to 15mg/kg taken twice daily) for two years.
There is no proven safe or effective dose for stevia, and use in children is not recommended.
Avoid in individuals with a known allergy or hypersensitivity to stevia or the daisy family (Asteraceae/Compositae). Other members of the daisy family include ragweed, chrysanthemums, marigolds, and many other herbs.
Stevioside may lower blood glucose levels. Caution is advised in patients with diabetes or hypoglycemia (low blood sugar), and in those taking drugs, herbs, or supplements that affect blood sugar. Serum glucose levels may need to be monitored by a healthcare provider, and medication adjustments may be necessary.
Myalgia (muscle pain), muscle weakness, dizziness, asthenia (loss of strength), nausea, and abdominal fullness have been reported after taking stevioside. These effects resolved after the first week of treatment. Stevia may also lower systolic and diastolic blood pressure in patients with high blood pressure. Use cautiously in patients with hypotension (low blood pressure) or taking hypotensive drugs since various human and animal studies have shown that stevioside may significantly decrease systolic and diastolic blood pressure.
Higher doses of stevia may affect renal activity and perfusion, sodium excretion, and urinary flow. Avoid using stevia therapeutically in patients with impaired kidney function or other kidney diseases until human safety data is available.
Stevia is not recommended in pregnant or breastfeeding women due to a lack of available scientific evidence.
