The Szechwan poisoning syndromeThe Jelly Ear (also known as Jew's Ear) and related species (like the Clouded Ear, the famous "black mushroom" of Asian cuisine) are largely consumed throughout the world. They have well-known medicinal properties against thrombosis. However, an excessive consumption of this mushroom can lead to the Szechwan syndrome, which results in frequent bleedings caused by modifications of placelets (purpura: bleeding underneath the skin, inflammation and bleeding of gums).
This mushroom is also said to concentrate heavy metals (among which mercury).
