Natural Standard Bottom Line Monograph, Copyright © 2013 (www.naturalstandard.com). Commercial distribution prohibited. This monograph is intended for informational purposes only, and should not be interpreted as specific medical advice. You should consult with a qualified healthcare provider before making decisions about therapies and/or health conditions.

While some complementary and alternative techniques have been studied scientifically, high-quality data regarding safety, effectiveness, and mechanism of action are limited or controversial for most therapies. Whenever possible, it is recommended that practitioners be licensed by a recognized professional organization that adheres to clearly published standards. In addition, before starting a new technique or engaging a practitioner, it is recommended that patients speak with their primary healthcare provider(s). Potential benefits, risks (including financial costs), and alternatives should be carefully considered. The below monograph is designed to provide historical background and an overview of clinically-oriented research, and neither advocates for or against the use of a particular therapy.

  • Note: Stevia rebaudiana should not be confused with Stevia salicifolia, also called ronion or roninowa. Stevia salicifolia contains the bitter glycoside stevisalioside.

Background

  • Stevia (Stevia rebaudiana) leaf extracts have been used for many years in traditional treatment of diabetes in South America. Paraguay's rural and indigenous populations have used stevia for birth control.

  • Rebaudioside A and stevioside are steviol glycoside compounds extracted from stevia that are used as natural sweeteners or dietary supplements. These compounds reportedly possess up to 250 times the sweetness intensity of sucrose.

  • Available research is promising for use of stevia in high blood pressure and type 2 diabetes, although more well-designed clinical trials are needed.

Scientific Evidence

Uses

These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.

Grade*

High blood pressure

Some evidence suggests that stevia may have blood pressure-lowering effects. More research is warranted to compare its effectiveness with the current standard of care.

B

Hyperglycemia

Limited evidence suggests that stevia may lower blood sugar in people with hyperglycemia (high blood sugar). However, further research is necessary before a firm conclusion can be drawn.

C

*Key to grades:A: Strong scientific evidence for this use; B: Good scientific evidence for this use; C: Unclear scientific evidence for this use; D: Fair scientific evidence against this use (it may not work); F: Strong scientific evidence against this use (it likely does not work).

Tradition/Theory

The below uses are based on tradition or scientific theories. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious and should be evaluated by a qualified health care professional.

  • Alcohol abuse, antibacterial, anti-inflammatory, antimicrobial, antimutagenic (prevents gene mutations), antineoplastic (antitumor), antioxidant, antiviral (human rotavirus activity), birth control, diarrhea, digestive aid, diuretic (increased urine flow), energy, food additive, immune system regulation, obesity.

Dosing

The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.

Adults (18 years and older)

  • For high blood pressure, the following doses have been taken by mouth: stevioside (250 milligrams) capsules three times daily for three months; capsules containing 500 milligrams of stevioside powder taken three times daily for two years.

  • For high blood sugar, the following doses have been taken by mouth: one gram of stevioside with meals; water-based extracts of five grams of stevia leaves taken at regular six-hour intervals for three days.

Children (under 18 years old)

  • There is no proven safe or effective dose for stevia in children.

Safety

The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.

Allergies

  • Avoid in people with a known allergy or hypersensitivity to stevia or to members of the daisy family (Asteraceae/Compositae). Other members of the daisy family include ragweed, chrysanthemums, marigolds, and many other herbs.

Side Effects and Warnings

  • Stevia may cause abdominal fullness, dizziness, altered kidney function, changes in sodium excretion, changes in urine flow, muscle weakness, muscle pain, and nausea.

  • Stevia may cause low blood pressure. Caution is advised in people taking herbs or supplements that lower blood pressure.

  • Stevia may lower blood sugar levels. Caution is advised in people with diabetes or hypoglycemia, and in those taking drugs, herbs, or supplements that affect blood sugar. Blood glucose levels may need to be monitored by a qualified healthcare professional, including a pharmacist. Medication adjustments may be necessary.

  • Use cautiously in people with low blood calcium, impaired kidney function, kidney diseases, in people using agents that widen blood vessels (specifically calcium channel blockers), children, pregnant women, breastfeeding women, or for periods longer than two years.

  • Avoid in people with a known allergy or hypersensitivity to stevia or to members of the daisy family (Asteraceae/Compositae). Other members of the daisy family include ragweed, chrysanthemums, marigolds, and many other herbs.

Pregnancy and Breastfeeding

  • Use cautiously in pregnant or breastfeeding women, due to insufficient available data.

Interactions

Most herbs and supplements have not been thoroughly tested for interactions with other herbs, supplements, drugs, or foods. The interactions listed below are based on reports in scientific publications, laboratory experiments, or traditional use. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy.

Interactions with Drugs

  • Stevia may cause low blood pressure. Caution is advised in people taking drugs that lower blood pressure.

  • Stevia may lower blood sugar levels. Caution is advised when using medications that may also lower blood sugar.

Interactions with Herbs and Dietary Supplements

  • Stevia may cause low blood pressure. Caution is advised in people taking herbs or supplements that lower blood pressure.

  • Stevia may lower blood sugar levels. Caution is advised when using herbs or supplements that may also lower blood sugar. Blood glucose levels may require monitoring, and doses may need adjustment.
