Spirulina Extract is an outstanding food source which is a powerful tonic for the immune system and which can prevent or inhibit cancer in humans. These vegetable-derived capsules (both Kosher and Halal certified) are filled by hand with a manual encapsulation machine, not with a high speed automatic machine, and thus, only pure, unadulterated Spirulina 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. Several studies show Spirulina and its Extracts can prevent or inhibit cancers in humans and animals. Some common forms of cancer are thought to be a result of damaged cell DNA, causing uncontrolled cell growth. Cellular biologists have defined a system of special enzymes called endonuclease which repair damaged DNA to keep cells alive and healthy. In vitro studies suggest the unique polysaccharides in Spirulina Extract enhance cell nucleus enzyme activity and DNA repair. This might be the reason why several scientific studies, observing human tobacco users and experimental cancers in animals, reported high levels of suppression of several important types of cancer after the feeding of whole Spirulina or its water Extracts. Spirulina is also a powerful tonic for the immune system. In scientific studies of several different animals, Spirulina consistently improved immune system function. Medical scientists find Spirulina not only stimulates the immune system - it actually enhances the body's ability to generate new blood cells. Important parts of the immune system, the bone marrow stem cells, macrophages, T-cells and natural killer cells, exhibit enhanced activity. The spleen and thymus glands show enhanced function. Scientists also observed that Spirulina Extract caused macrophages to increase in number and to become more effective at killing germs. Studies show that even small amounts of Spirulina build up both the humoral and cellular arms of the immune system. Spirulina accelerates production of the humoral system (antibodies and cytokines), allowing it to better protect against invading germs. Spirulina is one of the most concentrated natural sources of nutrition known. It contains all the essential amino acids, and is rich in chlorophyl, beta-carotene, and other natural phytochemicals. Spirulina is the only green food rich in GLA essential fatty acid. GLA stimulates and makes skin and hair shiny, soft,  and more durable. GLA also acts as an anti-inflammatory, sometimes alleviating symptoms of arthritic conditions.
