Overview

Cordyceps is a type of parasitic fungus with a long history of use in Traditional Chinese Medicine. It is revered for its ability to improve energy, stamina, and athletic performance. For respiratory health, cordyceps is particularly beneficial as it has been shown to improve oxygen utilization, enhance lung capacity, and exert anti-inflammatory effects on the airways. This makes it valuable for both athletes and those with compromised lung function.
