Can pregnant women take lingzhi (Reishi mushroom)?
Generally speaking, pregnant women can consume Ganoderma lucidum (Reishi mushroom) in moderation, but should do so cautiously. A detailed analysis is as follows:

Ganoderma lucidum is a traditional Chinese medicinal herb rich in various nutrients, such as polysaccharides and triterpenoids, which have functions including immune regulation and antioxidant effects. During pregnancy, a woman's body undergoes special physiological changes, and her immunity may fluctuate. Consuming Ganoderma lucidum in appropriate amounts may help enhance the expectant mother's immunity and assist in disease prevention.
In addition, the calming effect of Ganoderma lucidum may help relieve anxiety and improve sleep quality in pregnant women. However, individual constitutions vary; some pregnant women may have a "hot" body constitution, and taking Ganoderma lucidum might lead to symptoms such as heatiness (excessive internal heat), which could be harmful. Therefore, it is recommended to take it under the guidance of a physician rather than taking it blindly on one's own.
When choosing Ganoderma lucidum products, ensure they are purchased from reputable sources to guarantee product quality and safety, avoiding counterfeit, substandard, or contaminated products.
