Reishi Mushroom
灵芝 · Líng Zhī
Quiets the mind and supports steady immunity
What it does
Reishi calms a busy mind, supports sleep, and gives immunity a long-term boost. In TCM, it nourishes the heart and quiets the spirit, easing palpitations, restless sleep, and low-grade anxiety that won't switch off. It also strengthens lung qi for chronic cough. Two trials and three reviews track effects on cardiovascular markers, immunity, and cancer support.
How to take it
Decoct 6–12g of dried sliced reishi in 4 cups water for 60–90 minutes (it's woody). Drink 1–2 cups daily. Standardized capsules are also widely available.
Try a daily reishi capsule or tea during high-stress periods
Add dried slices to long-simmered soups and broths. Decoct with chicken or beans for 1+ hours.
Simmer reishi slices with chicken broth for 90 minutes for a deep, savory tonic soup

Where it comes from
Reishi (Ganoderma lucidum) is one of the most revered tonic mushrooms in Asian traditions. Its Chinese name Líng Zhī means 'spirit mushroom,' reflecting its centuries-old reputation as a longevity botanical. Reishi appears in classical Chinese, Japanese, and Korean medicine, often depicted in Daoist art alongside immortals. Three systematic reviews cover cardiovascular markers, immunity, and cancer adjuvant use.
