Can people live a long life if they eat "all pine tea" on the market

Recently, some readers reported to discovery weekly that there is a kind of all pine tea on the market This kind of tea made of pine bark and pine leaves can not only strengthen the body, but also cure all kinds of diseases The advertisement lists a series of diseases that can be treated, such as insomnia, cold, hyperlipidemia, hypertension, Hypolipidemia, coronary heart disease, etc., which can be treated almost from head to foot Readers have questioned whether the pine bark and leaves are so magical? So if we want to live a long life, we should eat leaves and bark What hospital should we go to So I hope the reporter can answer for him With the same confusion, reporters began to look for answers Is this pine really good for all diseases? There are medical records of pine needles in ancient medical books The reporter has consulted a lot of information about pine trees There are many kinds of pine trees, 10 genera and 230 species, which are widely distributed all over the world Pine trees are the most widely distributed in China According to the flora of China, there are 22 kinds of pine trees, 10 varieties, 36 introduced varieties, and 70 kinds of pine trees in 2 varieties There are 48 species of pine that can be used for medicine Pine is one of the oldest plants on the earth There were pine trees in the age of dinosaurs The habit of eating pine needles and drinking pine needle tea existed in ancient China In ancient times, people believed that they must absorb the essence from ever young objects by imagination and reasoning In their observation of natural phenomena, they found that pine and cypress have the most vigorous vitality and the longest life span, so they will naturally eat them In a book called "pine needle revolution", Sun Simiao, a great medical expert in Tang Dynasty, had a special love for pine trees, and established such natural health preservation methods as "taking pine nuts, taking pine leaves and taking turpentine" Li Shizhen also mentioned in compendium of materia medica: "the pine leaves, named as the pineal hair, are warm and bitter in nature, nontoxic, enter the liver, kidney, lung, spleen and other channels, and treat various viscera, swelling and toxin, and rheumatism." He also said that it can treat blisters, promote hair regeneration, strengthen the liver, kidney, heart, spleen and lungs, and can satisfy hunger and prolong life So, do pine trees contain substances that can prolong life? There is indeed an anti-aging substance in pine pines Wang Fei, teacher of the school of chemical engineering, Nanjing Forestry University, told reporters that pine trees do contain a lot of nutrients Different pine parts contain different nutrients For example, pine bark contains a kind of antioxidant proanthocyanidins oligomer (OPC, also known as oligoprocyanidins, or procyanidins), and the content is very high Proanthocyanidins are widely distributed in the plant kingdom and belong to the natural polyphenol compounds derived from double yellow copper Proanthocyanidins are astringent and have strong antioxidant properties They usually exist in the peel, seeds and other parts of fruits Their main function is to protect the easily oxidized components in plants Ji Ling, President of the hypertension branch of the Chinese geriatric medical committee, told reporters that proanthocyanidins were first discovered in 1947 by the French scientist Max Kerry He found that there was a substance in peanut skin that had not been identified and had a very bitter taste - flavonoids He also found that when the substance was used in animal experiments, the blood vessel strength of animals could be doubled in a short period of time, the permeability of blood vessels could be significantly reduced, and the experimental mice with edema could be significantly improved The substance Dr meskley found was proanthocyanidins Later, scholars found a lot of proanthocyanidins in pine bark and grape seed, and the content in pine was more than that in grape seed However, it is more difficult to extract from pine trees, so grape seeds are the most widely used material source at present However, after years of research, the technology of extraction from pine trees has become mature Jiling herself is one of the people who has been engaged in this research for a long time and has obtained many patents on the use of pine needles Gilling said that proanthocyanidins can resist the oxidative damage of oxygen free radicals to human cells, enhance the function of human immune system, reduce low-density lipoprotein, reduce the prevalence of cardiovascular diseases, and help the human body absorb and utilize vitamin C, vitamin E, etc It is closely related to the connection between human tissues, blood vessels and muscles, so as to avoid wrinkles caused by skin thinning and collapse, prevent skin aging and make people look more beautiful Now many cosmetics often take this as the selling point Proanthocyanidins can not be synthesized by themselves in the human body, and they are easy to be lost in the cooking process, so they are difficult to be ingested by the human body, so they need to be extracted from plants through professional methods Besides pine bark, pine needles also contain a lot of nutrients, such as amino acids, protein, crude fiber, β - carotene, calcium, phosphorus, iron, copper, selenium, zinc and so on Among the amino acids in pine needles, there is a substance called arginine, which has a very good protective effect on the cardiovascular system It can be directly involved in the production of nitric oxide Nitric oxide is the main regulator of blood pressure, which can be produced in human arteries, nerves and other defense systems In the life system, the nitric oxide released by cells is very few The human body can use the secreted nitric oxide to kill the invading viruses, bacteria, parasites and cancer cells Of course, the more the human body needs for nitric oxide, the better Excessive release of nitric oxide in the air will lead to nitric oxide poisoning, resulting in methemoglobinemia, neurasthenia syndrome, coronary heart disease, etc Under normal circumstances, arginine of pine needles will participate in the production of nitric oxide, and the release amount is just right It can regulate blood pressure in two directions and protect the cardiovascular system So some people will collect pine needles to make tea, but Wang Fei said that because the taste of pine needles is very bitter, it is very difficult to drink directly, so few people will eat it directly Generally, it is made into health products and nutrition products after extraction to sell Pine trees have both nutrient elements and pollution elements Since the whole body of pine trees is treasure, no matter what form of pine products are edible? The answer is not always the same Wang Fei said that due to air pollution and environmental deterioration, it is not necessarily safe to eat pine products without any treatment The nutrient composition of pine itself is non-toxic and will not have side effects However, whether pine trees absorb some pollutants from the surrounding environment, such as heavy metals and other substances, has not been finally ruled out, and it may not be safe to eat them directly Moreover, pine trees are also vulnerable to pine caterpillars, pine nematodes and other pests If the treatment is not clean, eating is not healthy Li Wen, director of Pharmacy Department of Nanjing Hospital of traditional Chinese medicine, also told reporters that the medicinal value of pine trees is still under development So pine needle leaf is only used as a health product at present But in the folk also has the collection pine needle to make the tea, the edible practice However, the pine needles collected in the wild are not suitable for everyone Some people will have side effects after eating, such as nausea, vomiting, etc Therefore, people are generally not recommended to collect pine needles for consumption Moreover, there are many kinds of pine trees, not all of which can be used for medicine If we don't know how to pick it up by mistake, we can't keep healthy, but we may have side effects It needs to be reminded that, Ji Ling told reporters, the whole pine tea contains the bark of five kinds of trees, including cypress, ginkgo, spruce, redwood and pine These five kinds of trees have a long life, so some people take these five kinds of trees as their selling points However, the bark of cypress, gingko and sequoia trees all have certain toxicity Up to now, the health department has not listed them as health food materials If they are not handled properly, they will be harmful to human body So we must pay attention to the quality of pine products When picking pine needles, it's easy to absorb pollution If you want to pick pine needles and cook by yourself, it's not absolutely necessary, but you need to deal with it properly She said that the method of collecting pine needles should pay attention to the following points: first of all, do not pick pine trees with a growth period of less than 6 years That is juvenile pine trees When they do not bloom and bear fruit, they have incomplete nutrients The survival time of pine needles on trees is 4-8 years, and that of Pinus massoniana and Pinus tabulaeformis is about 4 years From the perspective of resource protection, it is better to collect needles close to the trunk There are usually old pine needles with complete nutrients Secondly, it is better to plant pine needles above 3m in the city, and try not to pick urban landscape pine trees The pine needles have a thick wax protective layer, which can prevent water loss After being contaminated with pesticides, the pesticides will be absorbed slowly and will be polluted for a long time Moreover, pine needles have strong adsorption capacity, and the small heavy metal particles such as soot, carbon particles, lead and mercury in the air are easily absorbed Pine needles secrete oil, which will be contaminated with dirt and difficult to clean In addition, pine needles in places with pollution sources should not be picked Pine trees have the function of purifying air, but they are most afraid of air pollution When they encounter harmful gases such as sulfur dioxide and hydrogen fluoride, they immediately appear yellow leaves and withered leaves So don't pick pine needles with yellow leaves After the pine needle is collected, it cannot be used immediately Pine needles are oily plants, easy to contaminate, not easy to clean To use to go greasy, wash food detergent to wash carefully, can also use soft hair brush After washing, soak in water or light salt water for 2-3 hours If there is no detergent, it can also be washed with alum for water purification or alkali bubble water for pasta Generally speaking, the wild pine needles in the mountains have few attachments and are easy to clean If there are a lot of oil stains under the pine tree, or the hands are stained with oil when picking, and there are white attachments on the pine needles, it must be that the pine tree is suffering from pests The white adherent is the oil of the pine tree secreted from the place where the insect bites In spring and summer, pine trees will be damaged by pine caterpillars, which are one of the major forest diseases and insect pests in China The larva of pine caterpillars has toxic hairs on its body surface When people touch the larva of pine caterpillars, their skin is easy to be stabbed, so they should be very careful when picking When eating, we should pay attention to the quantity, because the pine needle tea is more bitter, and its taste is not as good as tea, which may be one of the reasons why the ancients finally chose tea instead of pine needle tea So people who have just tried can choose to drink lighter, and people who are used to drinking can drink stronger If you drink too much at first, people who don't adapt are likely to feel sick and nauseous.
