Adding to the body of scientific knowledge about Spirulina, Cyanotech Corporation (Nasdaq:CYAN) announced new clinical evidence suggesting that the use of Spirulina stimulates the human immune response to cancer. Cyanotech supplies Hawaiian Spirulina to 35 countries and markets a specialty line of Spirulina Pacifica(R) products under its Nutrex Hawaii brand.
This is the second cancer study with Spirulina on humans and the first to suggest a possible mechanism. Japanese researchers at the Osaka Center for Cancer and Cardiovascular Diseases found that a hot water extract of Spirulina taken orally caused a statistically significant increase in both the number and the effectiveness of immune cells called natural killer cells. The findings were first reported by a Spirulina producer, Earthrise Nutritionals, which helped sponsor the study. Results of the study have been published in the medical journal, "International Immunopharmacology," vol. 2, number 4.
In discussing the latest research, Gerald Cysewski, PhD., CEO of Cyanotech, said, "While the current study by the Japanese researchers was with a relatively small group of subjects, the positive findings, coupled with earlier encouraging results, suggest an important role for Spirulina in supporting the immune system and the body's defenses against cancer."
An earlier double-blind peer-reviewed human study conducted in India and published in "Nutrition and Cancer," found that consumption of one gram of Spirulina daily for one year resulted in a 45% remission of oral leukoplakia in tobacco chewers compared to a 7% response in the placebo group. Oral leukoplakia is characterized by pre-cancerous lesions in the mouth. Additional research conducted at Harvard University had showed similar benefit with extracts of Spirulina in combination with natural beta-carotene in reducing chemically induced oral tumors in hamsters.
