Políporo o Polyporus

Polyporus umbellatus

Nome usuale in castigliano: Polyporus
Nome scientifico: Polyporus umbellatus o Grifola umbellata
Nome usuale in inglese: Umbrella polypore
Nome giapponese: Choreimaitake
Nome cinese: Zhu-ling

Si tratta di un fungo commestibile a carne bianca fibrosa non troppo apprezzato né in Occidente né in Oriente. Nutrizionalmente, a parte l’alto contenuto proteico, è noto per la sua relativa abbondanza di rame e zinco.

Azione diuretica

Favorisce l’eliminazione di un eccesso di liquido linfatico di alcuni edemi e la famosa “ritenzione di liquidi”.

Sistema immunitario

Aumentando la fagocitosi indotta da polisaccaridi.

Azione terapeutica secondo la Medicina Tradizionale Cinese (MTC)

Usato contro il Tang (catarro nel senso più ampio) e il blocco dei meridiani per l’acqua stagnante. È comunemente impiegato come diuretico e per molte condizioni del tratto urogenitale (calore e umidità nella zona addominale inferiore). Anche per problemi renali, calcoli e colica renale associata.
