Benefits & Medicinal Uses

Yarsagumba (Cordyceps Sinensis) improves general health and well-being. It detoxifies the body and boosts immunity, which helps to prevent several diseases. It is beneficial for the heart, lungs, reproductive organs, brain and blood vessels. In general, it improves blood circulation, oxygen uptake, stamina, and endurance. Therefore, it is popular among athletes and used by them for increasing their performance. However, Cordyceps supplements are very expensive but available in form of extract capsule, powder capsule, liquid extracts and tablets forms.

Physical Performance

Cordyceps Sinensis Supplement improves physical performance by increasing metabolic threshold and ventilatory threshold, a double-blind and placebo-controlled study suggested. (4, 5)

However, a contradictory study conducted on male cyclists concluded no effects on endurance exercise performance and aerobic capacity. (6)

Traditionally, it is used as performance enhancer and energy boosters by sportspeople, especially in China. Now, it becomes famous in the western world as well. It is likely to attenuate a rise of fatigue or exhaustion after physical performance. (7)

A rat study conducted with swimming test suggested increase in time to feel or become fatigue by 12.5% in rats taking Cordyceps supplement, as we discussed, it attenuates a rise of fatigue after exercises. (8)


Traditionally, Yarsagumba (Cordyceps) is used to reduce fatigue and stress and to improve the physical performance. It boosts the ATP level in the liver and muscles, which help to increase the energy level, reduce fatigue and improve performance. (9, 10)

Furthermore, Yarsagumba also reduces and delays the lactic acid accumulation in the muscles, which reduces exhaustion and stress, improves physical performance and increases the stamina. The similar results are found in a rat study using swimming test. (11, 12)


Yarsagumba has been used to prevent and delay aging and to reduce the effects of aging. It is commonly prescribed by herbalists and experts of traditional medicine for the weakness, fatigue, and impotence linked with aging. The anti-aging effects are attributed to its antioxidant action. Its extract increases the activity of catalase, superoxide dismutase, and glutathione peroxidase and decreases the activity of monoamine oxidase and reduces lipid peroxidation level. Further, it improves the neurological functions, especially memory and learning. It is also likely to prolong the lifespan by inhibiting oxidative stress. (13, 14)

Traditionally, Yarsagumba is used in elderly people for preserving strength, restoring the health and treating geriatric problems. It is also used after illness for reducing physical debility and mental stress.

Chronic Stress

Yarsagumba (Cordyceps Sinensis) reduces chronic stress in the brain. Chronic stress causes chronic inflammation in the brain, which causes various mental disorders and imbalance in neurotransmitter levels. It is responsible for memory impairment and decline in cognitive functions. Chronic stress can also cause depression, mood disorders, and neurodegeneration. Neurodegeneration can lead to the development of amnesia, dementia, Alzheimer’s disease and Parkinson’s disease. Yarsagumba reduces inflammatory markers, which indicates improvement in brain health. It is likely to restore the balance of neurotransmitters and lowers chronic stress. It also improves the levels of 5-HTP and brain-derived neurotrophic factor (BDNF). Therefore, Yarsagumba supplementation is helpful in controlling stress, depression and mood disorders. (15)

Memory Impairment

Yarsagumba (Cordyceps) improves memory and retention span by lowering chronic inflammation in the brain, as discussed above. It also exerts anti-oxidant action by increasing the level of glutathione and superoxide dismutase. It helps to prevent the decline of mental functions and improves the memory. (16)
