Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Reishi mushroom (Ganoderma lucidum) has a long history of use in traditional Chinese medicine, where it is valued for its supposed immune-modulating, anti-inflammatory, and adaptogenic properties. While there is a strong tradition of using reishi for general health, vitality, and to manage symptoms like fatigue or pain, there is little direct evidence from either traditional or scientific literature specifically supporting its use to treat Fibromyalgia Syndrome (FMS). Some contemporary herbalists and natural health practitioners may suggest reishi for fibromyalgia, mainly due to its traditional uses for fatigue and its potential to mitigate stress and inflammation—two factors thought to contribute to fibromyalgia symptoms.

On the scientific front, research on reishi has focused more on its potential effects on immunity, inflammation, and certain chronic illnesses, but studies directly evaluating its efficacy for fibromyalgia are lacking. A few small pilot studies or anecdotal reports may mention symptom improvement, but these are neither robust nor widely replicated. Therefore, while reishi is sometimes used as a supportive supplement in integrative care for fibromyalgia, its use is primarily justified by tradition rather than by scientific validation, and the evidence supporting its effectiveness for fibromyalgia is weak (rated 1 out of 5). Anyone considering reishi for fibromyalgia should consult a healthcare provider, especially due to possible interactions and contraindications.
