Palmaria palmata, often called Dulse by the Anglo-Saxons, is a seaweed from the Rhodophyta family. In Iceland, where it is better known by the name of "Söl", it has been eaten since at least the 10th century.
"Ribes rubrum", the botanical name for redcurrant, means sour, acidic and red. It is also called "Castillier" or "Gadelier" (in Normandy) or "Raisin de mars" (March grape). It has been known for its medicinal properties since the Middle Ages.
The name "Chamomile" is derived from the Greek words "Khamai" (on the ground) and "Melon" (apple) and no doubt refers to the apple-like smell of its flowers. This gave the Latin word "Chamaemeleon", which went on to become "Chamomile" in English. Cultivation of Chamaemelum nobile (or Anthemis nobilis) developed in Europe, which led to it being called "Roman" chamomile by the German physician Joachim Camerarius, who discovered it in Rome in the 16th century.
