Caput baroniae is the seat of an English feudal barony. (Baronia, nominative case of a feminine Latin noun, is correctly baroniae in the genitive.). Caput is also used in medicine to describe any head like protuberance on an organ or structure, such as the caput humeri.
To my surprise, it is even a cure for damp and heat arthritis. The thought of mung bean as a cause of arthritis is an old myth and total lie since scientific community already solved the answer.
Whole mung beans have a green skin. When the skin is removed in processing, the beans are usually split as well, exposing their pale to dark yellow insides. The darkness of the yellow insides will vary by variety. The ones sold with skins off are called either peeled, skinless, decorticated or hulled.
