Cordyceps sinensis, also known as Dong Chong Xia Cao or Caterpillar Fungus, is a widely used traditional medicinal herb in China. It belongs to the fungi family, with a unique life cycle involving a parasitic relationship with caterpillars.

The process begins when the fungal spores infect the larvae of ghost moth caterpillars. As the fungus grows inside the caterpillar, it gradually absorbs its nutrients and minerals, ultimately killing the host. Over time, a mushroom-like structure emerges from the caterpillar’s head, forming what is known as Cordyceps sinensis.

Due to this fascinating transformation, Cordyceps is also referred to as “The Caterpillar Herb.”
