Important Context Note
Research on Reishi mushroom (Ganoderma lucidum) is ongoing. Current evidence suggests potential benefits related to immune modulation, fatigue support, and general wellness, but many human studies remain small or preliminary. Reishi should not be considered a cure or replacement for medical treatment.
