Reishi Mushroom for Stress Relief

Research suggests that Ganoderma lucidum, commonly known as reishi mushroom, may have potential benefits for stress relief and mood regulation, with evidence coming from a small but directionally consistent body of literature. A 2024 randomized controlled trial found significant improvements in psychological stress measures among female college students who supplemented with Ganoderma lucidum, while a 2021 pharmacological review identified anxiety, sedation, and depression as areas of noted research interest for this fungus. A 2025 systematic review broadened this picture by examining reishi alongside other medicinal fungi, finding that preclinical studies point to plausible mechanisms involving neurotransmitter systems, stress hormone pathways, neuroinflammation, and the gut-brain axis. However, limitations are meaningful — the human clinical evidence remains sparse, studies often involve specific populations, and researchers have called for greater standardization of preparations and more rigorous clinical trials before firm conclusions can be drawn about effectiveness for stress relief in the general population.
