Oreja de Judas (Auricularia auricula-judae)

Writing in 1694, herbalist John Pechey described A. auricula-judae by saying "It grows to the Trunk of the Elder-Tree. Being dried it will keep a good year. Boyl'd in Milk, or infus'd in Vinegarm 'tis good to gargle the Mouth or Throat in Quinsies, and other inflammations of the Mouth and Throat. And being infus'd in some proper Water, it is good in Diseases of the Eyes."[7] The species also saw use as an astringent due to its ability to absorb water.[7] There are recorded medicinal usages from Scotland, where it was again used as a gargle for sore throats, and from Ireland, where, in an attempt to cure jaundice, it was boiled in milk.[15] The medicinal use of A. auricula-judae continued until at least 1860, when it was still sold at Covent Garden; at the time, it was not considered edible in the United Kingdom.[7]
