This mushroom is believed to be a powerful remedy by its name in Chinese, ​ling zhi​, which translates to "herb of spiritual potency," according to PeaceHealth. Reishi Mushroom is included in supplements, extracts, tea blends and even in coffee products. But you'll want to talk to your doctor before taking any Reishi Mushroom — especially if you're on medications

Reishi Mushroom Tea Benefits

While Reishi is linked to better immunity, gut health, cancer therapy and lower blood pressure, it's unclear how these findings would translate to Reishi Mushroom tea. More research is needed to fully understand the purported benefits of Reishi tea.

Side Effects of Reishi Mushrooms

Taking too much Reishi Mushroom may cause adverse effects such as the following, per MSKCC:

• upset stomach
• skin rashes
• nausea
  

Reishi Mushroom's side effects may include nausea and insomnia in some people with cancer. In rare cases, liver toxicity was a reported side effect.

Chronic diarrhea in a man with non-Hodgkin's lymphoma following long-term use of a powdered Reishi Mushroom extract also occurred.

Liver damage is the harshest side-effect when consumed for extended periods, usually over a year, though this risk is incredibly low. The mushrooms may interact negatively with prescription medication or other supplements you may be taking.

People Who Should Avoid Reishi

According to MSKCC, the following groups of people should avoid reishi or talk to their doctors before taking it.

• Those on blood thinners:​ Do not take reishi if you are currently taking blood thinners including warfarin, as it may increase bleeding.
• Those on immunosuppressants:​ Reishi can enhance immune response and might make your meds less effective
• ​Those undergoing chemotherapy:​ It's theorized that reishi might make chemotherapy drugs less effective.
  
• ​Those on substrate drugs:​ If you are taking cytochrome P450 2E1, 1A2, and 3A substrate drugs, do not take reishi as lab studies suggest compounds in reishi may affect drug concentrations.
  
• ​Pregnant people:​ Talk to your doc before taking any Reishi Mushroom supplements.
