Scientific tests have discovered that small amounts of spirulina, even after cooking, greatly enhance health, fertility and color in birds. This broad spectrum of beneficial effects indicates that spirulina possesses a very stable yet highly effective unidentified substance. The results of feeding trials are often so striking that scientists suspect several substances in this unique food may be responsible. Among these is a natural substance called sulfoglycolipid. Spirulina is an especially rich source of anti-viral sulfoglycolipid.
Scientists now know that spirulina extracts can protect hamsters from herpes virus and cancer.
American universities are studying spirulina to determine if it is useful for treating avian viruses such as Newcastles disease. Research currently being conducted will lead to a better understanding of this remarkable food. This blue-green algae is much different from common seaweed. Spirulina is a tiny, freshwater phytoplankton. Under a microscope it looks like loosely coiled springs.
