Cocoyam or Taro or Dasheen or Eddoe or Gwaza (Hausa): A tuber crop worth writing about.
Depending on the locality, taro could be called cocoyam, elephant ears, dasheens or eddoes. The taro plant is a member of the calla lily family and is technically a corm.
Cocoyam is a tuber crop used mainly for human food in the tropical and subtropical regions of the world. It is a dietary staple in the Pacific Islands, where the leaves as well as the tubers are utilised. It is also used in Asian and Caribbean cuisine.
It is commonly grown amongst small scale farmers who operate within the subsistence economy. In the past, it was regarded as a less important crop and its cultivation and consumption still lie within the less privileged farmers.
The starch-rich tubers of taro are the main product, but the young leaves are also eaten as a leafy vegetable.
Taro is thought to be a very old crop, originating in India and is thought to have been cultivated for over 10000 years, longer than wheat or barley.
It was mentioned by ancient Roman and Greek historians and was an important crop in the Mediterranean long before potatoes. Gwaza starch is one of the most nutritious, easily digested foods.

Side Effects of Cocoyam
One major limiting factor in the consumption of cocoyam is the presence of oxalates which impart acrid taste or cause irritation when foods prepared from it are eaten.
The anti-nutritional factors found in taro or cocoyam include oxalates, proteinase inhibitors, phytates, tannins, alkaloids, steroids and cyanogenic glucosides.
All parts of the raw taro plant contain the toxic compound, calcium oxalate, which must be destroyed by thorough cooking before eating.
Other secondary metabolites found in Gwaza include alkyl-resorcinols, phenolics, saponins, essential oils, resins, numerous sugars and organic acids. Acridity has been attributed to the presence of bundles of calcium oxalate crystals in the tissue of cocoyam known as raphides.
Contact of the raw tuber and leaf with the mouth or skin results in considerable itchiness, acridity and discomfort. Ingestion of foods containing oxalates has also been reported to cause caustic effects, irritation to the intestinal tract and absorptive poisoning.
Moreover, consumption of large doses of oxalic acid causes low plasma calcium and renal damage. Oxalates are also known to interfere with the bio-availability of calcium. Calcium in the form of calcium oxalate is not available because oxalates tend to precipitate calcium and makes it unavailable for use by the body, thereby, causing kidney stones.
Cocoyam must always be eaten cooked because it is toxic when raw. In order to reduce the effect of anti-nutrients, which may have some health-hazards, proper processing before consumption is necessary.
Cooking improves digestibility, promotes palatability, improves keeping quality, and also makes root crops safer to eat. Taro has quite a number of medicinal uses.
Cocoyam corm is used as an abortifacient for animals as a result of mismatching, and to treat tuberculous ulcers, pulmonary congestion, crippled extremities, fungal abscesses in animals, and as an anthelmintic. Its foliage is used as an astringent and poultice. The stem sap is used as a treatment for wasp stings.
