Traditional Uses in TCM

Cordyceps species like Ophiocordyceps sinensis have been used in TCM for centuries as:

  • A tonic to enhance kidney yang and replenish essence [1,2]
  • An invigorator for the lung and kidney to ease breathing difficulties [1]
  • A remedy to stop bleeding and dissolve phlegm [1]
  • A general wellness enhancer [1,2]

The combination of the Cordyceps fungus and the caterpillar host has been highly valued as a potentiator of longevity, strength, and vitality. It was reserved for royalty during the Qing dynasty. [3]

In TCM theory, Cordyceps is considered warming and sweet in nature. [4] It nourishes lung and kidney yin and yang, making it useful for yang deficiency conditions. [5]

Potential Health Benefits

Though high-quality clinical trials are still needed, preliminary research suggests Cordyceps may offer certain benefits:

  • Exercise Performance: By increasing ATP production, Cordyceps may boost energy levels and endurance during exercise. [6,7]
  • Immunity: Compounds like polysaccharides in Cordyceps may stimulate immune cells and proteins. This may enhance resistance to infections and cancers. [6,8]
  • Oxygen Utilization: Cordyceps may improve oxygen uptake, which could benefit respiratory conditions and exercise capacity. [6,9]
  • Libido and Fertility: As an aphrodisiac, Cordyceps may boost sexual health and fertility, especially in cases of yang deficiency. [10]
  • Kidney Health: Cordyceps may protect kidney function by reducing inflammation and oxidative damage. This could help chronic kidney disease. [11,12]
  • Lung Health: Through its actions on lung qi and fluid metabolism, Cordyceps may relieve cough, wheezing, and shortness of breath. [5]
  • Heart Health: By regulating cholesterol and triglyceride levels, Cordyceps may reduce some heart disease risk factors. [13]

Safety and Side Effects

Cordyceps is generally well tolerated but may cause mild stomach upset or dry mouth in some. [14] Safety concerns include:

  • Contamination with heavy metals like arsenic, due to Cordyceps’ growth environment. Only high-quality, lab-tested products should be used. [15]
  • Hormonal effects that may worsen estrogen-sensitive cancers. Cordyceps is not recommended for breast, ovarian, or uterine cancer patients. [16]
  • Blood sugar lowering and immune effects that require caution in diabetes and autoimmune disorders. Monitor blood sugar and symptoms closely if using Cordyceps. [14]
  • Blood thinning effects that increase bleeding risk when combined with anticoagulant or antiplatelet drugs. [17]

Due to limited safety data, Cordyceps is not recommended for children, pregnant/nursing women, or people with bleeding disorders. [14]

Conclusion

Cordyceps has a long history of traditional use as a tonic and lung/kidney remedy in TCM. Preliminary research shows it may offer exercise, immune, respiratory, kidney, heart, and sexual health benefits. However, due to quality control issues and potential side effects, consult your doctor before using Cordyceps supplements.
