(Natural News) Researchers from South Korea investigated the efficacy of a Cordyceps mycelium (Paecilomyces hepiali) culture extract (CBG-CS-2) in enhancing the immune system and evaluated its safety in healthy adults. The results of their study were published in the journal BMC Complementary and Alternative Medicine.

• Cordyceps is an herb used in traditional Chinese medicine (TCM). It is known for its various biological activities, which include immune-enhancing effects.


• For their study, the researchers prepared CBG-CS-2 to confirm its effects on the immune system. They recruited 79 adults and divided them into two groups: 39 adults comprised the intervention group, while 40 adults comprised the control group.


• The intervention group received 1.68 grams per day of CBG-CS-2 in capsule form for eight weeks.


• The researchers assessed the activities of natural killer (NK) cells and the serum levels of monocyte-derived mediators before the treatment and after eight weeks.


• They reported that, compared with the control group, the intervention group showed a significant enhancement of NK cell cytotoxic activity after eight weeks of treatment. This confirmed the positive effects of CBG-CS-2 supplementation on immune function.

Based on their findings, the researchers concluded that the immune system functions well with CBG-CS-2 supplementation and that the cordyceps extract is a safe and effective way of enhancing cell-mediated immunity in healthy adults.
