Caterpillar mushroom, also known as Cordyceps sinensis or Ophiocordyceps sinensis, has a long history of use in traditional Chinese and Tibetan medicine. It has been used as a tonic to improve stamina, lung function, and overall vitality, and is sometimes employed by traditional practitioners to support liver health, including conditions like hepatitis. The rationale in traditional medicine is based on its perceived ability to restore balance and strengthen the body’s defenses, rather than on direct antiviral action.

Scientific evidence supporting the use of caterpillar mushroom for hepatitis is limited and mostly preliminary. Some in vitro and animal studies suggest that Cordyceps extracts may have hepatoprotective effects, possibly due to antioxidant, anti-inflammatory, and immunomodulatory properties. These studies indicate potential for reducing liver damage or supporting liver function. However, robust clinical trials in humans with hepatitis are lacking, and there are no authoritative guidelines recommending its use for this condition.

In summary, the use of caterpillar mushroom for hepatitis is primarily rooted in tradition, with some suggestive but insufficient scientific evidence. More rigorous clinical research is needed before it can be recommended as a supportive or therapeutic agent for hepatitis.
