Are They Good For You?
Reishi mushrooms may have several beneficial properties, but further research is necessary to really understand this fungus.
With 400 unique bioactive components, it is understandable that mushrooms could have positive and negative effects on the human body. There is no conclusive evidence to support claims of potential benefits. However, they may boost the immune system, relieve stress, help with respiratory issues, and help relieve the symptoms of other ailments.
Reishi mushrooms may cause an upset stomach and skin rashes. The mushroom may cause nausea, itchiness, nosebleeds, insomnia, dry mouth, and bloody stool in some people.
Liver damage is the harshest side-effect when consumed for extended periods, usually over a year, though this risk is incredibly low. The mushrooms may interact negatively with prescription medication or other supplements you may be taking.
Should You Try Reishi Mushrooms?
Some supplements may contain only certain components of the mushrooms or a harmless quantity.
Talk to your doctor before trying a supplement containing Reishi mushrooms.
Several factors may influence the potential side effects of the mushrooms, including dose, the mushroom form (natural, powdered, or extract), and how long the mushrooms are taken.
Like so many things, there is no black and white answer. To be safe, always consult your doctor before taking any new supplement.
