Cactus berries are sweet and sour. Cactus is high in potassium, low in sodium and low in sugar, and its sugar content is lower than lettuce and cucumber. Cactus has always been a traditional food in the United States, and it is an indispensable characteristic vegetable and fruit in people's daily life. People wash and chop the cactus and cook it in soup, or bake it on the stove, or make it into cake stuffing, or directly pickle the fresh cactus, and some of it is used to make wine (tequila).

There are many kinds of cactus plants, all of which have poisonous thorns. If it is planted artificially, it can be bought from the supermarket. It is an edible cactus. Edible cactus is rich in nutrition, contains a lot of vitamins and minerals, and has the functions of lowering blood sugar, blood lipid and blood pressure. The tender stems of edible cactus can be eaten as vegetables, and the fruit is sweet. Old stems can also be processed into health care products and medicines with the functions of reducing blood fat and cholesterol. Edible cactus is one of the vegetables with the highest content of vitamin B2 and soluble fiber. Every 100g edible cactus contains about 220μ g of vitamin A, 0/6mg of vitamin C/kloc-0, 6 g of protein/kloc-0 and 2.7mg of iron, which can generate 25-30kcal of heat.

In the Mexican market, the tender stems of some flaky cacti can be sold as vegetables, and cacti can be eaten. Cakes, snacks and dishes in Mexico are famous. They are cooked with the flowers of local cactus plants. In Mexico, there are 10 1 cooking methods for cactus, including steaming, frying, frying, soaking in barbecue and seasoning cold salad. Among them, spicy fried cactus, egg fried cactus and cactus salad are the most famous. People eat cactus and its tender stems. They cook with cactus leaves, which are usually peeled, boiled, sliced, oiled and seasoned to make cold dishes. If you do stir-fry, you don't have to cook it, just cut it and cook it.

get a facial

Cut the cactus with a knife, take its juice and apply it to your face. /kloc-Wash with clean water after 0/5 minutes, which has the effect of whitening and hydrating.

cactus

Cactus known as the "oxygen bar" at night.

Cactus mostly breathe in cool and humid nights. When breathing, inhale carbon dioxide and release oxygen.

Dust adsorption master

Placing a cactus indoors, especially hydroponic cactus (because hydroponic cactus is cleaner and more environmentally friendly), can purify the environment.

Water storage function

There is a layer of wax on the surface of cactus, and the leaves have evolved into needles, which reduces the external area and thus reduces water transpiration.

Cactus evolved fleshy tissues, waxy skin, sharp thorns and specialized roots, which gave them all the growth advantages in this difficult ecological environment. The trunk is like a reservoir, which can expand and contract according to the amount of water it stores, and the chlorophyll on it replaces the leaves for photosynthesis. The wax protective layer on the skin can keep moisture and reduce water loss. Sharp thorns can prevent thirsty animals from treating it as a free drink.

They usually develop many shallow roots, only a little below the surface, and the distribution of roots can extend to several feet around to absorb as much water as possible. When it rains, cactus will grow more roots. When it is dry, its roots will wither and fall off to keep water supply. Edwards said: "cactus is more closely combined with water than the soil in which it grows." When growing, cactus faces the risk of losing soil moisture, so it has to be separated from the soil. "But during the sandstorm, it is easily blown away.

No radiation protection

Cactus has no radiation protection effect. Many people think that cactus lives in the desert, where the environment is dry and the "solar radiation" is very strong, so show cactus a hat that can prevent radiation. In fact, this statement has no scientific basis, and some uneducated people believe it. At the same time, some unscrupulous merchants hyped it up, which made this original wrong statement more deeply rooted in the hearts of the people.

Cactus is a cactus plant, cactus Alias fairy palm, Guanyin palm, overlord tree, dragon tongue, etc. They are mainly distributed in arid areas of tropical and subtropical regions such as South America, Africa, southern China and Southeast Asia.

Cactus is a plant that inhales carbon dioxide and releases oxygen at night, so it is called "oxygen bar" at night.

Cactus, on the other hand, likes strong light, which has been magnified and labeled as a "tall hat" that can absorb computer radiation.

This amplification is not completely unfounded. Steven vogel, a professor of biology at Duke University in the United States, described in a paper in 2007 that the peak temperature of solar radiation is 5800K, which is the temperature of visible yellow light in the spectrum. This is very important for photosynthesis of plants. Nevertheless, in the desert where the daytime temperature can reach 46 degrees Celsius or even higher, there are very few species of plants that can survive. Cactus grows well in the desert.

So some merchants claim that cactus can survive under 5800K solar radiation, so cactus can absorb strong radiation. Although this statement is unscientific, consumers are still very useful in this age of radiation discoloration.

Yao, a professor of horticulture at Beijing Agricultural College, once told the media that cactus grows in a desert with strong sunlight and can resist the damage of sunlight and ultraviolet rays. But sunlight produces a kind of "radiant energy", which is different from the radiant light produced by computer screens or other electrical appliances. Radiation is an energy wave that travels in a straight line. Nothing can divert radiation, and the statement of "absorbing" radiation is obviously inaccurate. Moreover, no research report has ever proved that cactus is superior to other plants in absorbing radiation. Therefore, in order to absorb radiation and reduce the harm to the body, putting a cactus next to the computer is completely inferred and has no scientific basis.

If you really want to reduce computer radiation for your health, you can control your time in front of the computer and keep an appropriate distance.

Other uses

Cactus contains toxic alkali, which can act on the central nervous system after eating, causing various hallucinations. It was an important plant in Peru from the first century to the seventh century.
