What is a wrought oyster? What are roasted oysters?

Roasted oysters are made from oysters, the meat is fat and smooth, delicious and nutritious, oysters are different from oysters, oysters have the effect of astringency and astringency, acid and pain, and calming the nerves, and are often used as traditional Chinese medicine.

Roasted oysters are a kind of traditional Chinese medicine, its effect is mainly to astringent and astringent, acid and pain, calm the nerves, soft and hard to disperse knots, mainly used for some slippage syndrome.

For example, spontaneous night sweats, urinary urgency and frequent urination, as well as women's sub-band leakage, men's spermatozoa, and pain and acid reflux for excessive gastric acid secretion are also effective; There are also dizziness, insomnia, and restlessness caused by hyperactivity of the liver yang, which can be used with oysters. Roasted oysters and raw oysters are different preparation methods, and their effects are slightly different. Raw oysters have a strong effect on calming the nerves and nourishing yin, softening and dispersing knots, so it has a better effect on insomnia, tinnitus and cough caused by hyperactivity of liver yang and liver and kidney yin deficiency; The oysters are mainly used for night sweats, slippage and other symptoms, as well as stomach pain, acid and stomach pain, and the effect of acid making and pain relief is better.

Oysters contain 80% 95% calcium carbonate and calcium phosphate, and the 1995 edition of the Chinese Pharmacopoeia stipulates that the preparation of oysters is "to take the oysters and calcine them until crispy". Roasted oysters: strong astringent and acid-removing effects, **stomach pain, stomach acid, etc.

Roasted oysters in 200 400, 1 4h, the characteristics are gray-green powder, slightly salty taste; In 600 800 1 4 hours, the character is yellow-white or white powder, bitter and sweet, spicy tongue, lime taste. Oysters should only be calcined at 200 400 and 1 3 hours, under which oysters can maintain some of the characteristics of raw oysters, and have the properties of oysters, and are easy to crush and decoction.

Oysters are oysters and oyster yellows, which are a group of shellfish species with short food chains, fast growth, high yields and wide distribution.

Oysters (scientific name: ostreidae), also known as oysters, oysters, and oysters, are a group of shellfish species with short food chains, fast growth, high yields, and wide distribution. Oysters have a wide variety of external morphologies, but they often have two unequal shells, no teeth in the hinges, and sometimes small nodular teeth.

There are 10 genera under the oyster family, which are Folded Oyster, Abnormal Oyster, Giant Oyster, Tooth Margin Oyster, Ridge Oyster, Dwarf Oyster, Oyster, Palm Oyster, Cyst Oyster, and Clawed Oyster.

The left shell of the oyster is larger, the body side is flattened, the left and right are symmetrical, with two mantles and shells, the mantle is located on the inner surface of the shell, thin and transparent, and its external morphology often changes greatly with the different living environments, and many oysters are difficult to distinguish by relying solely on the external morphology of the shell.

Oysters are widely distributed shellfish worldwide, and the western Pacific Ocean is a concentrated area of oyster resources. Oysters in China are cultivated in a wide range of coastal areas from the Yalu River in the north to Hainan Island in the south. Its meat is delicious and rich in protein, and it is known as "the milk of the sea".

Oysters are the main object of shellfish culture, and their production accounts for the first place in the world's shellfish aquaculture production. There are more than 100 varieties of oysters, and about 20 species in China. Among them, the varieties with greater economic value and have been cultivated and produced are:

Long oysters, European oysters, American oysters, table oysters, Greek oysters, Omi oysters, and pleated oysters, etc.

Oyster, the name of Chinese herbal medicine. This product is the shell of oyster Omi oyster, long oyster or Dalian Bay oyster. It can be collected all year round. After harvesting, remove the meat, take the shell, wash it, and dry it.

The shell of the long oyster is large, thick, elongated, dorsal and ventral almost parallel, and the shell length is generally 3 times higher than the shell. Left shell attached. The right shell is relatively flat as a cover, with ringed scales, corrugated, sparsely arranged, and few layers. The shell surface is lavender, grayish-white or yellowish-brown.

The inside of the shell is porcelain white. The adductor muscle marks are horseshoe-shaped, brownish-yellow, located dorsal to the posterior part of the shell. The left shell is concave and the scales are thicker than the right shell. The flesh is soft, and the gills are straight strips, not bent to the back corners. It is distributed along the coast of our country. It is a good breed for estuarine and inner bay culture.

Medicinal properties

irregular oval, triangular or oblong shells, varying in size, usually 10 30 cm long, 5 10 cm wide, 1 3 cm thick; The appearance is gray, light gray-brown or gray-blue, layered, and has curved rough layers. The inner surface of the shell is mostly milky white, smooth and shiny, with horizontal striations at the base, matte, and wavy laminar lines on the edges.

The left shell is thicker and larger than the right shell, uneven, and there are often conchs and mosses attached to the outside of the shell, and there are often holes on the surface, and there are small shells in the holes; The right shell is thin and small, and relatively flat. The texture is hard, not easy to break, the section is white, layered. There is no gas, and the taste is slightly salty.

It is better to be large, neat, and clean inside.

Oysters are a phylum of mollusks. Oysters are the world's largest farmed shellfish and one of the important marine biological resources available to human beings.

Oysters are one of the most stress-resistant aquatic animals, 200 million years of intertidal environment has trained oysters to temperature, salinity, open space and common pathogens in the sea area, when the tide is exposed, can tolerate the hot and dry weather in summer, but also can successfully adapt to the freezing weather in winter, can survive in the open water conditions for 1 2 weeks, or even 1 month.

The main source of oysters.

Oysters are a worldwide shellfish, with more than 100 species found and produced in almost every coastal country around the world. Most of Japan's oysters are the same as those in China, and the main types of oysters in Europe and the United States are table oysters, American oysters, and European oysters, and their total production is the largest among shellfish. During the Han Dynasty in China, bamboo began to be planted to raise oysters, and it has a history of more than 2,000 years.

China is rich in oyster resources, is the homeland of oysters, has a long history of using oysters, as early as more than 2,000 years ago, residents of some areas along the southern coast of China mastered oyster farming technology.

Oysters, also known as oyster yellow, oysters, oysters, belong to mollusks, there are three folds on their mantle, and there are sensory cells on the middle folds, which have tactile and visual functions, and oysters have strong resistance to stress, can survive for a month in an off-water environment, can use floating rafts when breeding, and regularly clean up barnacles, mussels and other predators.

Oysters, also known as oyster yellow, sea oysters, oysters, belong to the oyster family mollusks, its shell is divided into three layers, the outermost layer is the cuticle, the middle layer is the prismatic layer, the inner layer is the nacre, and the oyster has two layers of epithelial cells, and the edge of the mantle is divided into three folds, of which the middle fold has sensory cells.

In the process of growth, oysters will stick their shells to other objects to move or fix, mainly distributed in intertidal areas, and oysters have strong stress resistance, good resistance to temperature and salinity, can adapt to low temperature in winter, and oysters will show different genders in different years or environments.

Breeding oysters should choose the sea area with less wind and waves, stable water quality and no industrial pollution, and then set up a floating raft in the sea area, put the oyster seedlings in the floating raft, and in the process of breeding, it is necessary to regularly clean up barnacles, mussels, bryozoans, sea squirts and other organisms on the floating raft, so as not to affect the growth of oysters.
