Cordyceps Supplements: This new found mushroom, coming from China, is where we have derived all the studies done thus far.
The Chinese believe that this special fungus gives the body the ability to resist  all sorts of bacteria and viruses. They have some studies showing benefits against leukemia. I'm giving a short list below of some of the studied benefits:
improves libido
stimulate sex hormone
infertility in females
promotes muscle tone
inhances physical performance
anti aging
reduces fatigue
great antioxidant
promotes cellular growth
reduces anxiety
calms nerves
promotes restful sleep
reduces cough
bronchitis
asthma/relaxes walls of the bronchi
acts as a anti-inflamatory

This product is well worth the study to learn of all it's medicinal properties.

This provides a more palatable form to take than ingesting  a mushroom, with noticable results in 1-2 months.
