WARNING: DISCLAIMER: The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.


Adults (over 18 years old)

2-6 grams per day of reishi as raw fungus or an equivalent dosage of concentrated extract has been taken with meals. In clinical trials studying cancer, chronic hepatitis B, coronary heart disease, or diabetes, doses of 600-1,800 milligrams have been taken three times daily. For high blood pressure, Linzhi extract (reishi) has been used in doses of 55 milligrams a day for four weeks. For pain management in herpes zoster, 36-72 grams of dry weight per day for up to 10 days have been studied. Other doses used are 500-1,125 milligrams per day for the treatment of proteinuria (excess protein in the urine) or 100 grams of reishi boiled in 600 milliliters water per dose for poisoning.

Children (under 18 years old)

Insufficient available evidence to recommend.


DISCLAIMER: Many complementary techniques are practiced by healthcare professionals with formal training, in accordance with the standards of national organizations. However, this is not universally the case, and adverse effects are possible. Due to limited research, in some cases only limited safety information is available.


Avoid in individuals with a known allergy/hypersensitivity to any constituents of Ganoderma lucidum or any member of its family. Skin reactivity to spore and whole body extracts have been reported. Hypersensitivity reactions to reishi and its derivatives may occur including dry mouth, nosebleed, and nasal and throat dryness

Side Effects and Warnings

Acute and long-term studies have found Ganoderma lucidum to be generally well-tolerated in recommended doses for up to 16 months. The most common adverse events reported are skin rash, dizziness, and headache.

Use cautiously in patients who are taking diabetes/hypoglycemic drugs because reishi may lower blood sugar.

Low blood pressure may occur upon the utilization of reishi and its derivatives.

Due to "blood thinning" capabilities, gastric bleeding could result from the use of reishi. Reishi may prolong bleeding time and caution is advised in those patients with bleeding disorders (ulcers, hemophilia) or taking anticoagulants. Diarrhea and bloody stools may occur with supplemental doses. Mild gastrointestinal discomfort including nausea and diarrhea has been found in a small percentage of cancer patients taking Ganoderma lucidum as Ganopoly®.

Severe liver inflammation that led to death has been linked to reishi mushroom powder.

Pregnancy and Breastfeeding

Not recommended due to lack of sufficient data.
