There are many different species of Echinacea, and three of them are used in health products: E. purpurea, E. pallida and E. angustifolia. Of these three, E. purpurea is the most researched, most proven, most effective species of Echinacea.
The authoritative source on Echinacea, the German government Commission E, has stated that only two forms of Echinacea are proven effective for helping to support health:
1. Pressed juice of blooming Echinacea purpurea herb (the leaves and flowers), and preparations made from the juice;
2. Root extract or root of Echinacea pallida.
Most of the research showing benefits for immune support and supporting the health of the upper respiratory system has been done with Echinacea purpurea juice and Echinacea pallida root extracts. Yerba Prima was the first company to introduce an Echinacea product based on this research, called Echinace®, back in 1986.
Yerba Prima now has Echinace® Extra Strength in convenient capsules. Echinace® Extra Strength contains Commission E approved Echinacea purpurea herb juice in a concentrated powder form. In addition, Echinace® Extra Strength contains Commission E approved Echinacea pallida root extract, plus the powerful, patented assimilation-boosting nutrient Bioperine® black pepper extract. Echinace® Extra Strength is a unique product which gives maximum beneifts for health.
Echinacea helps support normal immune function, the body’s defense system. It is especially helpful for supporting respiratory health. Clinical studies have shown benefits for school children and others taking Echinacea purpurea herb juice on a daily basis to maintain good health, as well as powerful benefits for short term use. Recent research indicates that Echinace® will be most effective when taken at the first signs of congestion, when a person is just starting to feel bad or “off,” and then continuing to use the product for a few days up to two weeks.
