BCCT plans to write a summary on Agaricus blazei, one of several medicinal mushrooms. While our summary is in development, you can visit About Herbs: Agaricus Blazei
Use has been linked to severe liver dysfunction in three patients with unspecified cancers.1
Paul Stamets in MycoMedicinals notes that Agaricus blazei contains the carcinogen hydrazine, and we do not have data indicating whether or not the effects of these carcinogens mitigate the medicinal properties of these mushrooms. These carcinogens can be removed during processing, and these "detoxified" preparations are available. However, "consumers should beware that many of the A. blazei products being sold contain these potentially dangerous hydrazines."2
BCCT does not recommend therapies or doses, but only provides information for patients and providers to consider as part of a complete treatment plan. Patients should discuss therapies with their physicians, as contraindications, interactions and side effects must be evaluated.
Dosage recommendations are available from these sources:

Paul Stamets advises using mushroom products that contain both the water and alcohol extractions, since each contain different medicinally important compounds.6
Integrative oncologist and BCCT advisor Keith Block, MD, advises using extracts (rather than eating whole mushrooms) that are blends of several different medicinal mushrooms, including maitake (Grifola frondosa), agaricus (Agaricus blazeii), shiitake (Lentinula or Lentinus edodes), reishi (Ganoderma lucidum), turkey tail (Trametes or Coriolus versicolor), and caterpillar fungus or cordyceps (Cordyceps sinensis).7
