What are the symptoms if I am allergic to Reishi Mushrooms (Ganoderma lucidum)?

Having Reishi mushrooms continuously can bring in many positives in health. But, sadly, Reishi mushrooms can also cause allergic problems that can lead to big issues. Stomach upset, dizziness, rashes in the body, headache, and bleeding in the nose are common symptoms if you are allergic to it. Get a doctor's help if any of these things happen.
