Named source

Aloe vera, which evolved from Arabic allcoh, is a folk herb and has been loved by people since ancient times. "Lu" means black, and "Hui" means gathering. The juice dripping from the incision of aloe leaves is yellowish brown, which turns black after being oxidized by air and condenses into a whole, so it is called "aloe".

distribute

Aloe vera is native to tropical and arid regions of Africa. Generally speaking, aloe is considered to be a plant native to Africa. Aloe vera is now distributed almost all over the world. According to the survey, there are wild aloe in India and Malaysia, African continent and tropical areas. Aloe also exists in the wild state of Yuanjiang, Zhinan, China.

morphological character

Aloe vera is a perennial evergreen succulent herb. It has a long history. As early as ancient Egypt, its efficacy was accepted and recognized by people, and it was called "mysterious plant". Aloe vera is a Liliaceae plant. Leaves are clustered, sedentary or born at the top of the stem, often lanceolate or short and wide, with sharp teeth at the edge. Inflorescence is umbrella-shaped, raceme-shaped, spike-shaped, cone-shaped, with red, yellow or red spots, six petals and six pistils. Perianth base is connected into a tube shape.

Up to now, the earliest record of aloe that we know is in the ancient Egyptian medical book "Ai Panouse Papinus". Archaeological findings show that aloe vera was placed between the knees of mummies in Egyptian pyramids.

The book not only records the therapeutic effect of aloe on diarrhea and eye diseases, but also includes various prescriptions of aloe. This book was written in BC 1550, which means that aloe has been used as a medicinal plant for 3500 years. We can speculate that as early as 5,000 years ago, the Egyptian people should have used the Lu emblem earlier. After that, aloe vera was probably introduced to Europe because of Kyle's Victorian Empire. In 1 century BC, Theos Clerides, the physician of the Roman emperor, wrote a medical book "Clichy's Materia Medica", which contained specific prescriptions for using aloe for different diseases and called aloe a versatile herb. In addition, the New Testament also records that when people buried Jesus, they mixed Vetiveria zizanioides and aloe vera and painted them on his body.

Since then, the efficacy of aloe has been widely recognized in Europe, which was recorded in German pharmacy in the12nd century. This is the first time that aloe has been recognized in national laws. After that, Aloe Vera spread to China through the Silk Road. In China, people call it "aloe", and aloe also appears in Compendium of Materia Medica written by Li Shizhen, the ancestor of traditional Chinese medicine. In this book, aloe vera is not only regarded as a useful plant, but also recorded as "black resin", from which it can be inferred that China used a lump from Europe at that time, which was made by boiling the juice.

Aloe vera was introduced to Japan in Kamakura or Muromachi era, and it was called Aloe vera in Edo era (note: now Japanese people call it Aloe vera), so it can be seen that Aloe vera in Japan came from China. However, aloe at this time probably refers to Coptic aloe, which means that aloe was first introduced to Japan not as a plant, but as a medicine. This can be confirmed in Yamato Materia Medica by Ekiken Kaibara in the Edo period and Enlightenment of Compendium of Materia Medica by Lanshan in Xiao Ye. Lu Hui's illustrations in these books are mostly fictional. In addition, at this time, Portuguese missionaries also brought aloe vera to Japan, which is said to be wood blade aloe vera. Since then, with the spread of Christianity, aloe has been promoted all over the country, and in some places it has been promoted by the root propagation method of aloe.

During the Meiji period, due to studying German medicine and other reasons, Japan's medical system began to improve and Japanese pharmacies were established. Although aloe vera was included in pharmacies a long time ago, it did not immediately spread among the people. As a folk medicine, it has been widely used since the Second World War. After the war, scholars all over the world began to discover the pharmacological effects of aloe. In addition, wood blade Aloe and Aloe, which adapt to Japanese climate and local conditions, have excellent pathological effects. After this was proved, aloe was finally recognized by the Japanese as a kind of herbal medicine. Especially in the forty-fourth year of Showa (A.D. 197 1), Japanese medical scholars found that aloe had an inhibitory effect on cancer, and people's enthusiasm for aloe rose rapidly.

After that, Aloe also had a household name "No need for a doctor", and therefore, Aloe became a recognized medical authority by the general public.

How to use aloe and matters needing attention

First, the method of use

Aloe vera not only has a variety of medicinal effects, but also has many ways to use it, mainly for oral administration and external use.

1, oral

The easiest and quickest way to get the drug effect is to eat fresh leaves directly. You can also make fresh leaves into thin slices, sweet and sour stains, juice or fry them. Chewing raw aloe mesophyll can play a good role in conditioning and health care. It is advisable to eat15g of leaves every time. If raw chewing aloe leaves is not suitable, you can take fresh leaf juice. Adults take one spoonful each time, 2-3 times a day, and the dosage of children and the elderly can be reduced appropriately. Make tea or wine with dry leaves, make powder or granule medicine, make liquid juice, etc. Are all effective methods for oral administration.

2. External use

Aloe leaves are rich in mucilage. This liquid has the functions of preventing ulcer, promoting wound healing, stimulating cell growth and stopping bleeding. For external use, it can be directly applied with fresh leaves or medicated wine made of aloe. The external application method is relatively safe. Pay attention to choosing aloe leaves with high maturity, and the curative effect will be better.

Second, matters needing attention

To use aloe to treat diseases, we must first identify whether it is a medicinal aloe species, and avoid using agave, Raytheon or aloe species with ornamental value for disease prevention and treatment. Choose the variety of aloe, pay attention to its characteristics and usage, and prescribe the right medicine according to the cause. Proper use of aloe vera can achieve the best results. Don't overdo it or rush for success.

Correctly distinguish between the use of traditional Chinese medicine aloe (dry block) and fresh aloe, especially some inflammation, fresh aloe juice is much more effective than traditional Chinese medicine aloe.

Children with weak constitution should not take too much aloe vera, and allergic people will have red, swollen and rough skin.

Pregnant women and menstruating women are forbidden to take aloe vera. In ancient times, aloe was used as a gynecological medicine to treat amenorrhea and other symptoms. Because aloe can make the organs in female pelvic congestion and promote the movement of uterus. Therefore, pregnant women or menstrual women can easily cause abdominal pain, leading to bleeding and severe bleeding.

Patients with hemorrhoid bleeding and nosebleeds should not use aloe vera.

The first time you eat aloe vera, you should have a skin test first. If there is no abnormality, you can use. Because some people are allergic to aloe vera, such as redness, tingling, pimples and abdominal pain. Severe abdomen will have a burning sensation. If you take it orally for the first time, if you have symptoms such as nausea, vomiting or diarrhea, some are temporary. If this happens frequently, the drug should be suspended, reduced or heated. If allergic people want to eat, they can take a small amount for external use or oral administration, and then slowly increase it after the body adapts.

American FDA certification

Oral aloe certified by FDA can be used as a "structural/functional" dietary supplement, but it is not allowed to claim the efficacy of treating or preventing any diseases, nor is it allowed to indicate the therapeutic effect on the product label. According to the current FDA regulations, legal structural/functional descriptions include "enhancing immunity" and "enhancing heart function", but expressions such as "treatable AIDS" and "preventable cancer" are not allowed, because these expressions are used to refer to drugs.

Aloe vera for external use is recommended as a cosmetic ingredient. Structural/functional drug description is not allowed. It is allowed to use cleaning and beauty words such as "moisturizing", "lubricating" and "softening".

American regulatory commission certification

1975 aloe vera has been certified by FDA as an over-the-counter drug for constipation. 1998, three kinds of aloe were certified. The FDA requires manufacturers to submit additional safety information before June 2 1, 1, 999, which may restrict the sale of aloe as an over-the-counter medicine for constipation.

Beauty Function of Aloe Vera

Beautiful skin comes from aloe vera, which is whiter, softer and smoother.

As early as BC14th century, Queen Neferti of Egypt used aloe vera to beautify her face, giving her delicate and fair skin and soft and smooth hair.

In ancient China, there were also records of aloe as a beauty product, such as Miscellanies of Lingnan: ... leaves are thick and sharp, but there are thorns on the edges, which will not blossom or bear fruit. Starting from the roots, they become more fragrant and their leaves are broken, which makes them beautiful ... Good people paint their hands with luster instead of oil, which is effective, also known as flowers, like Shandan. "

After World War II, the United States and many countries carried out systematic development and research, which expanded the functional fields of aloe. Besides medicine and food, it was also widely used in beauty cosmetics. Japanese, Korean and China Taiwan Province Province have also conducted research, utilization and development of new products.

In the late 1980s, there appeared a beauty craze of aloe in China. 1987, Shanghai Daily Chemicals Factory produced a series of beauty products, including nutrition cream, nutrition honey, sunscreen cream, facial cleanser, powder cake, lipstick, mask, sunscreen water, shampoo and conditioner. It occupies a large market in China and is well received by consumers.

Aloe juice is a natural extract, which contains a variety of moisturizing agents and nutritional functions beneficial to human body. According to scientific research, aloe contains hydrated products of polysaccharides, such as glucose, mannan syrup, a small amount of uronic acid and calcium. There are also a few trace elements needed by human body, such as hydrating protease, biological hormones, hormones, protein, amino acids, vitamins and minerals. Therefore, aloe vera has the following functions and has excellent beauty effects.

1, nutritional and moisturizing effect

Amino acids and compound polysaccharides contained in aloe constitute natural moisturizing factor (NMF). This natural moisturizing factor can replenish some water lost from the skin, restore the function of collagen, prevent facial wrinkles and keep the skin smooth, moist and elastic.

Because aloe contains polysaccharides and monosaccharides, and there is a trace of magnesium lactate, aloe gel has natural wettability, which delays the dehydration speed of cosmetic creams and shampoos. The experiment shows that adding aloe gel to oil-in-water emulsion can delay the evaporation rate of water.

Aloe vera gel can enhance water penetration. It can penetrate into the skin surface, allowing water to enter the tissue directly. Aloe gel increases its penetration into skin due to hydrolysis, blocking and increasing the solubility of compounds, which makes it enhance its penetration into skin. As a bite seal, polysaccharide and mucilage form a solid covering layer, which can prevent the evaporation of water on the skin surface.

After investigation, aloe vera gel can be used in various products. It has been pointed out that aloe gel can obviously be used to moisten products. Gel is not only compatible with anions, but also with nonionic and cationic systems.

Adding aloe vera gel to soap is a particularly meaningful idea. Its function is to make soap clean without drying the skin. Due to the mild nature of the gel, the prepared soap has no danger of irritation.

Aloe shaving cream is another application of polysaccharide in soap products. In the recommended formula 4, the gel is both a lubricant and a wetting agent. Because of its viscosity, aloe can almost act as a protective layer between skin and beard like silicon.

Gels have been used in many products to relieve burns. In addition to the so-called callus, it can also keep moist on the injured skin, which is the basic condition for the formation of callus. An extremely simple product that has proved to be effective is a spray composed of lidocaine hydrochloride and aloe gel to relieve burns. It is a basic product. In people's minds, it is a natural product, not a medicine.

These are just a few aloe gel products that can be used. In any system that needs mild humidification, aloe gel can be used alone or together with other raw materials. Therefore, aloe vera gel is an ideal natural moisturizing factor in various cosmetics.

2, sunscreen effect

Solar rays include infrared rays (>: 770 nm), visible light (400 ~ 770 nm) and ultraviolet rays (

In recent years, scientific research in dermatology has found that UVA ultraviolet rays account for 98% of the total energy of ultraviolet rays reaching human body, and its penetrating power to glass, clothes, water and human skin is far stronger than UVB ultraviolet rays. Although it has a slow effect on human skin, it will cause serious damage over time. UVA can induce photosensitivity and phototoxicity. In severe cases, it can also induce skin cancer. UVA is considered to be one of the main causes of skin aging.

Recent studies have pointed out that when people's skin is irradiated by ultraviolet rays, the main cause of sunburn is that ultraviolet rays will reduce and damage the immune function of the skin, which will reduce the resistance of the skin to foreign microorganisms and toxins, thus causing diseases and, in severe cases, forming tumors. Dr Faith strickland of the University of Texas Cancer Center pointed out that aloe vera gel is not only a sunscreen, but also can prevent ultraviolet rays from damaging the immune system, restore damaged immune function, cure sunburn and prevent the formation of skin cancer. It has achieved amazing results not only in the laboratory, but also in clinical trials, using aloe gel to treat sunburn. Experiments show that aloe polysaccharide can enhance and regulate immune function. Therefore, there is no doubt that aloe vera gel with sufficient concentration can play a role in sun protection in cosmetics, and can treat sunburn and prevent cancer.

3, anti-inflammatory, analgesic, burn, scald, cut and other wound healing effects.

Aloe vera gel is coated on the wound to form a thin layer, which can prevent the invasion of external microorganisms. Can keep dry wounds moist, and the growth factor in the gel can directly stimulate the regeneration and repair of fibroblasts. Aloe vera gel can enhance the tensile strength of sore surface, promote the treatment of sore surface and promote healing. Taylor, a professor of pharmacology at Purdue University in the United States, proved that a peptide called kinin can produce a substance similar to burn pain, and aloe vera gel can inhibit the effect of kinin, that is, aloe vera gel can alleviate and eliminate pain. The anti-inflammatory, analgesic and wound healing effects of aloe vera gel have also been confirmed by all people who have used it. According to a survey of 5,000 readers in American Journal of Prevention, 97% of readers rated aloe as the most useful and popular herb, which can relieve pain and cure sores. Professor Taylor's article says that aloe ranks first among seven kinds of healthy herbs.

Aloe gel is an ideal carrier. For example, when hydrocortisone is applied to the skin, 99% of the epidermis that cannot penetrate into the skin is wasted. When the medicine is put into aloe gel for the first time, the gel can well penetrate into the skin, bring the medicine into the skin and enhance the therapeutic effect of the medicine. Therefore, aloe vera gel is also the best carrier to transport various drugs.

4, immunomodulator

A normal immune system in an organism is a sign of health. Aloe vera gel contains a variety of active ingredients, which are dissolved in polar water of gel and cooperate with each other to form a powerful regulatory effect on external immune function. Acetylmannan, a polysaccharide extracted from aloe gel by Carrington laboratory in the United States, has been approved by FDA as a drug for treating AIDS, which has shocked the aloe industry. In fact, acetyl mannan plays the role of immunomodulator, inhibiting the invasion and reproduction of microorganisms and viruses to organisms. Some researchers isolated aloe glycoprotein Aloin A from aloe, which has strong anti-tumor activity. Aloe vera is used to treat diabetes. Long-term use of anti-aging effects. , has been reported. In recent years, "International Aloe Science Association" proposed that aloe can be used as a functional food other than food, medicine and cosmetics, and can be taken regularly and quantitatively.

In a word, aloe is not omnipotent, but it undoubtedly plays a role in regulating the immune system and really plays a role in health care, beauty and treatment. Therefore, people naturally apply it to cosmetics, health foods and medicines, and it is the best choice to play its due role.

It's important to see this. A lot of aloe vera will certainly be useful to you.

And there are pictures, which are more useful.

Cura? ao is generally cultivated at home, and Shanghai Agricultural University is a variety of Cura? ao. Generally, there are few flower markets. It is suggested to use Cura? ao instead.

Aloe vera SCA Gu, the scientific name of aloe vera. Skagu aloe is a more suitable aloe variety for protected cultivation. The aloe leaves of Shangnong are covered with white wax powder, and the leaves are green. The maximum blade length can reach 85 cm and the width can reach 12 cm. The mesophyll is thick, white and without bitterness. When potted, the tillering ability is very weak and the main stem is not branched. It is an excellent variety suitable for intensive and industrialized aloe production in the middle and lower reaches of the Yangtze River in China. It has great development and utilization value, fast growth speed and is also suitable for family cultivation.

China aloe is also called striped aloe. Chiyoda brocade, a Japanese ornamental plant, also called striped aloe, is actually different from China aloe.

Aloe vera is similar in appearance to cactus and agastaches, belongs to Liliaceae botanically, and is a perennial succulent herb. The Picture Book of Chinese Higher Plants records: Aloe vera, a perennial herb ... its origin is unknown, and some people think it originated in China.

Agave is called "aloe" in some places in southern Fujian. Minnan people have the habit of calling foreign objects "Fan XX" or "Fan Zi XX". For example: fan fire (matches), sweet potato, guava, pepper, muscovy duck and so on. The noun after "Fanzi" or "Fanzi" should be something that has existed in China since ancient times. Tequila has been introduced to China for a long time, which at least shows that before tequila was introduced to China, aloe vera, an "exotic product", was regarded as its own by China people.

Aloe sinensis is a variety of Aloe vera, which is similar in appearance to Aloe vera and contains similar chemical components. The experiment shows that the moisturizing effect of Chinese aloe juice is stronger than that of Cura? ao aloe juice, which is beneficial to the preparation of cosmetics, but not to the processing of Chinese herbal medicines.

In southern Fujian, Taiwan Province Province, Chaoshan in Guangdong, Beihai in Guangxi, Hainan Island, Yunnan and parts of Sichuan, people have the habit of potted aloe since ancient times, and women in many places have long regarded it as a natural hair care treasure, which has been passed down to this day. Besides being used as beauty products, folks have accumulated rich experience in using aloe. This kind of potted grass can often be seen in some places in the south, and many people know this kind of grass and its use. When it comes to aloe vera, most elderly people remember it vividly and can say a thing or two.

In southern Yunnan, the Dai and other ethnic minorities use wild China Aloe as herbal medicine and call it "scalding grass". Some people are scalded by soup fire, that is, they go to the mountains to pick aloe leaves, cut the epidermis and stick it on the affected area, which will immediately feel cold, and can also relieve pain and inflammation and prevent ulcers. When the scald is serious, mash the whole aloe into paste and apply it, and the effect is better. More importantly, aloe vera is used to treat burns, leaving almost no scars after recovery.

1938 published the 29th volume of Fujian Tongzhi, which recorded that "Hedyotis diffusa, which is produced in Fujian, is a cloud: it is produced in Fuzhou, fat as a dragon's tongue, with thorns on both sides, two or three feet high, more than a foot long in leaves, and red in flowers." "Hedyotis diffusa" here refers to China aloe, not agave. The "aloe" mentioned by Lu Xun in the article "Mr. Fujino in Sendai" refers to agave. The old gentleman has not lived in Xiamen for a long time and doesn't know much about Minnan dialect. No wonder he made mistakes.
