ImmunExtra® is the only immune product containing patented Proligna®, a natural water extract of pinecones that has been shown to enhance the production of human dendritic cells 9 fold in 9 days. More recently, laboratory research has shown that Immunextra reduces the Th2 arm of the immune system while at the same time promoting the Th1 arm of the immune system.
The health benefits of pinecone extract were first documented in 500 A.D. by the Greeks. Since that time, the extract has been used in modern day Japan, where it has long been associated with an increase in health and longevity. Try it to stay healthy. It is one of the only supplements tested to be safe in human studies at three independent medical centers in the United States.
