There are over 14,000 mushroom species in the world. 2,006 of these can safely be consumed. Mushrooms are commonly eaten for enjoyment and for being nutrient-dense. Shiitake can protect against cell damage, help your immune system, and boost white blood cell production for fighting off microbes. While, maitake can reduce your cholesterol, improving artery functionality and overall cardiovascular health to lower your risk for heart disease. Mushroom Cabin #4 is constructed of oak and supports shiitake, maitake, and oyster mushroom spores.
