New Roots Herbal’s Shiitake (Lentinula edodes) is a hot water–extracted medicinal mushroom formula, ensuring a potent product with a standardized 40% polysaccharide content (300 mg per capsule). Employing the traditional Asian extraction method, hot-water extraction is crucial for gently releasing medicinal components from the mushroom, as the indigestible chitin in the cell wall must be dissolved. This method surpasses grinding, which may damage long-chain polysaccharides and fails to remove indigestible chitin, limiting therapeutic constituents in each capsule. Standardization guarantees a consistent polysaccharide content, delivering a reliable therapeutic dose.
