Purchase a one pound package of Raintree's sustainably harvested pure stevia leaf powder (Stevia rebaudiana)—rich in active and beneficial phytochemicals that occur naturally in this plant. This is the natural green leaf ground into a powder, and not the white powder extract as sold by other companies. It has been sustainably wild-harvested in the Brazilian Amazon and it is rich in active and beneficial phytochemicals that occur naturally in this plant. Over 100 phytochemicals have been discovered in stevia thus far. It is rich in terpenes and flavonoids. The constituents responsible for stevia's sweetness were first documented in 1931, when eight novel plant chemicals called glycosides were discovered and named. Of these eight glycosides, one called stevioside is considered the sweetest—and has been tested to be approximately 300 times sweeter than sugar.* Stevioside, comprising 6-18% of the stevia leaf, is also the most prevalent glycoside in the leaf. Other sweet constituents include steviolbioside, rebausiosides A-E, and dulcoside A.* This plant has been milled into a fine powder which is suitable to stuff into capsules or to prepare your own teas, tinctures or extracts.

Traditional Uses:* as a natural sweetener; for diabetes; for high blood pressure; for cavity prevention; as a weight loss aid

Ingredients: 100% pure stevia leaves (Stevia rebaudiana). No binders, fillers or additives are used. It is a wild harvested product—grown naturally in the Brazilian Amazon without any pesticides or fertilizers.

Suggested Use: This plant is best prepared as an infusion (tea). Use one teaspoon of powder for each cup of water. Pour boiling water over herb in cup and allow to steep 10 minutes. Strain tea (or allow settled powder to remain in the bottom of cup) and drink warm. It is traditionally taken in 1/2 cup amounts, 3-4 times daily. This plant can be added to other herbs or beverages, stuffed into capsules, or simply stirred into water or juice. For more complete instructions on preparing herbal infusions, see the Methods for Preparing Herbal Remedies Page.

Contraindications: None reported.

Drug Interactions: In large amounts, it may enhance the effect of antihypertensive and antidiabetic medications.

Other Observations:

  • Stevia leaf (at dosages higher than used for sweetening purposes) has been documented to have a hypoglycemic effect. Those with diabetes should use high amounts of stevia with caution and monitor their blood sugar levels as medications may need adjusting.
  • Stevia leaf has been documented to have a blood pressure lowering effect (at dosages higher than used for sweetening purposes) . Persons with low blood pressure should avoid using large amounts of stevia and monitor their blood pressure levels accordingly for these possible effects.
