Ophiocordyceps sinensis is a parasitic fungus that primarily infects caterpillars in the Himalayan region. It grows inside the host, eventually killing it and emerging from the caterpillar's body as a stalk-like structure. This unique life cycle has made it a subject of interest in both ecology and medicine. Traditionally, Ophiocordyceps sinensis is valued in Traditional Chinese Medicine for its potential health benefits, including boosting energy and enhancing immune function. It is often harvested in the wild and sold as a high-priced natural remedy, contributing to its popularity and economic significance in local communities.
