Cordyceps sinensis has been described as a medicine in old Chinese medical books and Tibetan medicine. It is a rare combination of a caterpillar and a fungus and found at altitudes above 4500 m in Sikkim. It is also known as Caterpillar fungus. Traditional healers and local people of North Sikkim recommend the mushroom, i.e., Yarsa gumba, Keera jhar (C. sinensis) for all diseases either as a single drug or combined with other herbs.

It’s believed that the many anti-inflammatory benefits of cordyceps come from their ability to positively affect the immune system, fighting oxidation damage, and stimulating protective cells that keep the body free from mutations (like cancerous cells) and infections. Studies have found that cordyceps can act like natural cancer treatments in some cases, preventing the growth of tumors (especially in the lungs and on the skin).

In addition to fighting cancer, cordyceps are used to help treat  respiratory infections like chronic bronchitis, coughs, colds and the flu, asthma, kidney disorders, bladder infections and urination problems, , hepatitis B, low circulation and irregular heartbeats, heart disease and high cholesterol, liver disorders, muscle weakness, chronic fatigue syndrome and low energy, dizziness.

Cordyceps acts like a Natural Aphrodisiac. Traditionally, people of both sexes took tonics made from cordyceps to enhance their libidos and reproductive function. It appears that cordycep supplements can help the body utilize oxygen more efficiently and improve blood flow, which is important for physical health and sexual function. Thus, cordyceps can be utilized as a natural treatment for infertility and a natural remedy for impotence.
