Salt vs Tokoyo

Informations

Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater, where it is the main mineral constituent. The open ocean has about 35 grams (1.2 oz) of solids per liter of sea water, a salinity of 3.5%. Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and salting is an important method of food preservation. Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt-works in China dates to approximately the same period. Salt was also prized by the ancient Hebrews, the Greeks, the Romans, the Byzantines, the Hittites, Egyptians, and the Indians. Salt became an important article of trade and was transported by boat across the Mediterranean Sea, along specially built salt roads, and across the Sahara on camel caravans. The scarcity and universal need for salt have led nations to go to war over it and use it to raise tax revenues. Salt is used in religious ceremonies and has other cultural and traditional significance.

Salt is processed from salt mines, and by the evaporation of seawater (sea salt) and mineral-rich spring water in shallow pools. Its major industrial products are caustic soda and chlorine; salt is used in many industrial processes including the manufacture of polyvinyl chloride, plastics, paper pulp and many other products. Of the annual global production of around two hundred million tonnes of salt, about 6% is used for human consumption. Other uses include water conditioning processes, de-icing highways, and agricultural use. Edible salt is sold in forms such as sea salt and table salt which usually contains an anti-caking agent and may be iodised to prevent iodine deficiency. As well as its use in cooking and at the table, salt is present in many processed foods. Sodium is an essential nutrient for human health via its role as an electrolyte and osmotic solute. Excessive salt consumption may increase the risk of cardiovascular diseases, such as hypertension, in children and adults. Such health effects of salt have long been studied. Accordingly, numerous world health associations and experts in developed countries recommend reducing consumption of popular salty foods. The World Health Organization recommends that adults should consume less than 2,000 mg of sodium, equivalent to 5 grams of salt per day.

Tokoyo is a figure in Japanese mythology. She was the daughter of a samurai named Oribe Shima. Shima had displeased the Emperor, who was in an ill state of health, and was subsequently banished. As a result, he had to set up home on a group of islands called the Oki Islands, away from his daughter. Both he and Tokoyo were miserable at being separated, and she became determined to find him. She sold all her property, and set out for a place called Akasaki, which was just off the coast from the Oki Islands. Although she asked the fishermen to ferry her there, they all refused, since it was forbidden to visit anyone banished there. One night, she took a boat and sailed to the islands herself. She spent the night on the beach. The next morning while searching for her father she encountered a fisherman, whom she asked about her father. The fisherman replied he knew nothing, and warned her not to ask anyone else about his whereabouts. As a result, she was forced to eavesdrop on people's conversations, rather than simply asking them directly. Unfortunately, Tokoyo could not gather any useful information this way. On one evening, she came upon a shrine of Buddha, and after praying to him, collapsed and fell asleep. She was awoken by the sound of a girl crying, and looked up to see a young girl and a priest. The priest led the girl to the edge of a cliff and would have pushed her off the edge, if it wasn't for the intervening of Tokoyo.

The priest said he was going to sacrifice the girl in order to appease the god Okuninushi, who demanded the annual sacrifice of a young girl. Tokoyo offered to take the girl's place, begrieved and hopeless from not finding her father. After praying to Buddha again, she dived down into the ocean; dagger in her teeth. At the bottom of the ocean, Tokoyo found a mighty cave, which housed a statue. The statue was of the emperor who banished her father, and she immediately decided to destroy it. However, thinking better of it, she tied it to herself and began to swim back with it. Before she could leave the cave, a serpentine creature (not Okuninushi, but some unnamed monstrosity) confronted her. Devoid of fear, Tokoyo first stabbed it in the eye, blinding it, then relentlessly attacked until she succeeded in killing it. When she arrived at the shore, the priest and girl carried her to town. Word of her heroic deed spread. The emperor's unknown ailment had also suddenly been lifted. He realized that Tokoyo must have released him from a curse, because of what she did to the statue. He ordered the release of Oribe Shime. The father and daughter happily returned to their home town. Legend has it that the city of Edo was renamed to Tokyo in honor of Tokoyo.
