PRICE: $8.95 for each 60 capsule bottle (350 Mg per capsule) Barlowe's Herbal Elixirs presents a potent 4:1 extract from the aerial portions (herb) of Echinacea Purpurea. Click on this link: Echinacea Extract COA, to see  the Certificate of Analysis on this particular batch. These capsules are filled by hand with a manual encapsulation machine, not with a high speed automatic machine, and thus, only pure, unadulterated Echinacea Purpurea 4:1 Extract is in the capsules. Capsules produced with high speed machines in herbal remedy and vitamin "factories" contain several other ingredients, including preservatives because so many bottles of product are produced at one time, and lubricants to ensure that the machines will run faster and more efficiently. Check their labels! Also, Barlowe's Herbal Elixirs is one of the very few manufacturers that still pack their products in glass whenever possible, even though glass is more expensive.  Barlowe believes that chemicals can leach out of plastic containers and contaminate the contents, and that the use of glass is much better for the environment. The roots and herb (aerial portions) of Echinacea species have attracted recent scientific interest due to purported "immune stimulant" properties. Echinacea preparations were widely used by various American Indian tribes, and oral preparations are very popular in Europe and the United States for prevention and treatment of upper respiratory tract infections (URI) and colds.  Echinacea Purpurea herb is believed to be the most potent Echinacea species for these types of illnesses. In the United States, sales of Echinacea are believed to represent approximately 10% of the dietary supplement market. For URI and cold treatment, numerous human trials have found Echinacea to reduce duration and severity, particularly when initiated at the earliest onset of symptoms.  A 2006 meta-analysis investigating the efficacy of Echinacea found that the likelihood of experiencing a clinical cold was 55% higher with placebo than with Echinacea (based on three trials).  Caution: Barlowe's Echinacea Extract uses only the finest quality Echinacea Purpurea (4:1) herbal extract from the most trusted suppliers. This means that four kilos of Echinacea Purpurea herb are required to produce one kilo of the extract. This herb provides superb support to the immune system and it is generally safe, but it is potent and should be utilized with care. This product is for dietary use. If side-effects occur, discontinue use immediately! The above statements have not been evaluated by the Food and Drug Administration (FDA).
