CATDOLL : CATDOLL: Are cockroaches good for you?

Cockroaches are good food and can also be used as medicine. The medicinal value of cockroaches: [Functions and indications] They can promote blood circulation, nourish yin and promote muscle growth, enhance immunity, and disperse stagnation and eliminate accumulation.

At present, the American cockroach has the best effect as medicine. The alcohol extract of American cockroach has a significant inhibitory effect on cancer cells and has a significant effect on cardiovascular diseases. American cockroach is used as medicine in both dried and fresh adult forms. It is mainly used to treat children's malnutrition, tonsillitis, body masses, carbuncle swelling and pain, centipede and snake bites, etc. Modern research has found that the epidermis of American cockroach contains sclera and chitin, bromine, zinc, nickel, manganese, potassium, calcium, titanium, chlorine, sulfur, silicon, aluminum, magnesium and other elements. Muscle hydrolyzes 13 kinds of amino acids. In addition, the body stores vitamins B1, B2, niacin and ascorbic acid, etc., and the lymph contains trehalose, trehalase, glycoprotein, inositol, protocatechuic acid glucoside, etc. The whole body contains ergothioneine, lobster myoside, fenugreek, glycine, betaine, anal alkaloids, trimethylamine, adenine, etc. The main clinical applications are: treatment of children's malnutrition: fry 3-4 cockroaches, grind them into powder, add appropriate amount of hawthorn, decoct and take, 2-3 times a day, take several days; treatment of carbuncle and swelling: 3 American cockroaches and 1 centipede, mash them together and apply to the affected area; treatment of centipede injury: mash the adult cockroaches and apply to the wound; treatment of children's cold and fever: 6 American cockroaches, boil water to drink; treatment of unknown poisoning: 10 American cockroaches, add a pinch of salt and mash them together and apply to the affected area, leaving the poisoned head; treatment of insect and snake bites: American cockroaches are combined with yam, centipede, seahorse, and vitamin C and E, mainly for kidney cancer. American cockroaches are combined with Pseudostellaria heterophylla, Dendrobium officinale, Gastrodia elata, Jiaomuxiang, Poria cocos, Baiyao, and Hedyotis diffusa to assist in the treatment of colon cancer. American cockroach can cure hepatitis B, and its extract AT-2 preparation can treat primary liver cancer. Cardiovascular disease: The extract can treat cardiovascular disease. Of course, there is also a kind of cockroach called sea cockroach, which looks scary but tastes delicious.

Oral administration: used for blood stasis, stomach pain and bleeding, gastric and duodenal ulcers; and as an auxiliary treatment for yin deficiency pulmonary tuberculosis, liver disease, tumors, etc.

What is a cockroach? Hateful things, annoying things, things that make people bored, demons that carry germs, the harm of cockroaches is huge. So when you see cockroaches, don't think that this kind of thing can only bring us harm. "Compendium of Materia Medica", "Shennong's Herbal Classic" and other classics have also seen the effect of cockroaches in promoting blood circulation, treating poisonous sores and Lishui, as well as records of using cockroaches to treat diseases. At present, the effective ingredients of cockroaches have been used in many aspects. For example, chitin secreted from the body wall of cockroaches is a very important material in the manufacture of artificial eye masks and artificial skin. Although cockroaches have so many bacteria and germs on their bodies, these are not carried by the cockroaches themselves. Because cockroaches don't like these things either, they are just accidentally spread to their bodies in their living environment. From the perspective of the cockroach itself, it is also very beneficial to humans. From the perspective of the cockroach itself, many of the garbage we discard in life are digested by cockroaches. Many dead bodies in nature carry a large number of germs, and at this time cockroaches appear. They will eat all these things, so as to avoid the spread of a large number of bacteria and germs to every link in the food chain.

Cockroaches have survived for almost 300 million years. How many species have become extinct? Why can only cockroaches survive? There must be a magic weapon that allows them to survive. So what is the magic weapon? The places where cockroaches live are places where some bacteria like to live. So let's think about it. The places where cockroaches live are places where germs like to live. So why don't cockroaches get sick or die? Because there are some substances in the cockroaches that can be made into pesticides and fungicides in agriculture. Since cockroaches live in a dirty environment for a long time, there are still many antibiotics in their bodies. Humans can extract the antibiotics in cockroaches and use them for humans, so that humans can also be free from the invasion of various germs and bacteria. There is also the inspiration that cockroaches give to dynamics. Cockroaches run very fast, and humans can imitate their movements to make some machines that can run with low energy.

Everything has two sides. Looking at cockroaches from a positive perspective is also very helpful to us. So we should look at things from both sides. Maybe someday in the future, the cockroaches that we hate today will become our saviors in the future. However, if you have cockroaches at home, you must not keep them. No matter what method you use to kill cockroaches, you must eliminate these little creatures.

Cockroach is the common name for insects of the order Blattodea, also known as "cockroach" or roach.

Any of more than 3,500 species of insects in the suborder Blattaria, order Dictyoptera. The English word cockroach is a corruption of the Spanish word cucarcha. Cockroaches are one of the most primitive winged insects in existence (almost unchanged for 320 million years) and one of the oldest fossil insects. They are characterized by a flat, oval body, long, filamentous antennae, and a leathery, shiny black or brown body wall. The head is bent downward, with the tip of the mouthparts pointing backwards, rather than forward or downwards like most other insects. Males usually have two pairs of wings, while females are often wingless or have reduced wings, with an egg pod protruding from the body to carry the eggs. After the female excretes the egg pod, the nymphs hatch from the egg pod, initially white, but hardening and turning brown after exposure to air. Adult cockroaches are large, with some species having a wingspan of up to 12 centimeters (4.7 inches), and their structure and size have attracted the interest of biologists, who use them in the laboratory.

Cockroaches prefer warm, moist, dark environments and are therefore usually found in tropical or other warm climates. Only a few species are pests to humans. Cockroaches destroy more material than they need to eat and secrete a foul-smelling fluid. Cockroaches feed on both plant and animal matter, including human food, paper, clothing, books, and dead insects, especially bed bugs. Cockroaches can be controlled with insecticides.

The American cockroach (Periplaneta americana) is 30-60-500 mm long (up to 2 inches long), light reddish brown, and lives outdoors or in dark, warm indoor environments (such as basements and rooms with furnaces). The adult stage lasts about 1.5 years. The female can lay 50 or more egg pods, each containing about 16 eggs, which hatch into nymphs after 45 days. The nymph stage lasts 11-60-14 months. The American cockroach is native to tropical and subtropical America, has well-developed wings, and can fly long distances.

The German cockroach (Blattella germanica) is a common indoor pest. It is light brown with two black stripes on the prothorax. Females lay eggs three days after mating and carry them for about 20 days. It is small, about 12 cm (less than 0.5 inches) long, so it is often brought into homes in grocery store bags or boxes. It has been carried around the world by ships. It can produce three or more generations a year. German cockroaches were first found in large numbers around the water pipes of the Croton Aqueduct in New York City, hence the common name Croton bug.

The Brown-banded Cockroach (Supella supellectilium) is similar to the German cockroach, but slightly smaller. The male has well-developed wings that are slightly lighter than the female, whose wings are shorter and nonfunctional. Both sexes have two light stripes across their backs. Adults live 200 days. There may be two generations per year. Eggs may be laid in clothing, wooden planks, or floor cracks. With the advent of heated homes, the Brown-banded Cockroach has also appeared in cooler areas.

The Oriental cockroach (Blatta orientalis) is considered the dirtiest household pest. It is oval, black or dark brown, shiny, and 25-6-5-30 cm long. Its life cycle is similar to that of the American cockroach. The male has short and well-developed wings, while the female has degenerate wings. It originated in Asia and was later distributed to all temperate regions by merchants' transportation.

Wood cockroaches are not pests of homes. The Pennsylvania wood cockroach (Parcoblatta pennsylvanica) is the common wood cockroach, found under wood and stone in high latitudes. The male and female are so different in appearance that they were once considered two species. The male is 15.6525 mm long, with wings that are longer than the end of the abdomen. Cryptocercus punctulatus has certain protozoa living in its digestive tract, so Cryptocercus can digest wood.

[Classification of cockroaches] Class Insecta, Order Blattaria. Sometimes specifically refers to the family Blattidae.

【Characteristics of cockroaches】 Flat, dark brown, usually medium-sized. Small, mobile head. Long, filamentous antennae, well-developed compound eyes. Flat wings covering the back of the abdomen; some species are wingless. Can't fly, can run fast. Incomplete metamorphosis. Lay eggs in egg sheaths. There are about 6,000 species (some say more than 2,250), mainly distributed in tropical and subtropical areas. Live in the wild or indoors. There is the American cockroach, which is the largest individual and is often kept as a pet.

[Tracing back to cockroaches] Originated from the Devonian period with other insects, cockroaches are scavengers that like to hide during the day and come out at night, living in caves. They can withstand the test of extreme heat and cold, and are widely distributed today. Cockroaches are one of the oldest insects on the planet and once lived in the same era as dinosaurs. According to fossil evidence, primitive cockroaches appeared on Earth about 400 million years ago in the Silurian period. The fossils of cockroaches we find or the cockroaches found in coal and amber are not much different from the ones in your cupboard. Its appearance has not changed much over hundreds of millions of years, but its vitality and adaptability have become more and more tenacious. It has been multiplying to this day and is widely distributed in all corners of the world. It is worth mentioning that a cockroach with its head removed can survive for 9 days, and the cause of death after 9 days is excessive hunger.

Yes, improve food utilization

A biologist once made a conclusion based on the ecological habits of cockroaches: If a global nuclear war broke out on Earth one day, all creatures in the affected area, including humans and even fish, would disappear, and only cockroaches would continue their lives!
