Not all wild vegetables are named "green"
The "nature" of wild vegetables lies in their "wild" nature, which can be described as natural food. People generally believe that as long as they grow in the soil, they will rarely be contaminated. Dr. Wang warned that most of the wild vegetables that occasionally grow in urban green spaces have been contaminated by car exhaust, insecticides, etc. Since water from most factories is discharged after repeated use, and the sewage treatment capacity is insufficient, the content of toxic substances in industrial wastewater will be quite high. When picking wild vegetables, try to avoid easily polluted areas by roadsides and rivers. When buying in the market, you must smell the smell first. If there is a pungent odor, you must eliminate it. Wild vegetables polluted by the air can easily absorb lead, and wild vegetables growing near wastewater often contain toxins, so they should not be eaten. The "Malantou" chosen by the aunt above is not actually a "green food". If you really want to find wild vegetables, you have to go to the countryside to find real wild lands. But don't mistake the vegetables grown by farmers as wild vegetables...
To dig wild vegetables, you must first look for them. The fields are overgrown with weeds and green everywhere. People will be dazzled for a while. Where to start? In fact, there are unlikely to be wild vegetables in the overgrown areas, probably because you don't want to "complicit" with them. Some wild vegetables, such as shepherd's purse and alfalfa, like to grow together in clusters. Furthermore, it’s best not to eat wild vegetables you don’t recognize. Some wild plants contain highly toxic substances, which can cause chest tightness, abdominal distension, and vomiting in mild cases, and life-threatening in severe cases. In addition, you should develop a good habit of soaking vegetables in water before cooking, especially when washing wild vegetables, and wash them several times.
Eating wild vegetables predicts "sex"
Wild vegetables can be eaten hot or stir-fried, or used cold (after blanched in boiling water). Common wild vegetables include bitter greens, dandelion, shepherd's purse, bracken, Chinese toon, purslane, etc. According to Dr. Wang, most wild vegetables are cool in nature and cold, and are helpful in "reducing fire" and improving immunity. For example, shepherd's purse has the effects of strengthening the stomach and spleen, improving eyesight and stopping bleeding, diuresis and detoxification. There is a folk saying that "shepherd's purse is a panacea". It is said that Malancai can clear away heat and detoxify, stop bleeding and diuresis, and has certain effects on bleeding gums, hepatitis, high fever in children, convulsions, etc.; alfalfa is a good medicine for stopping bleeding and relieving asthma; purslane is anti-inflammatory, cooling, and detoxifying, and has the effect of preventing dysentery. It is effective in treating gastric and duodenal ulcers, oral ulcers and other diseases.
However, Dr. Wang also emphasized that eating too much wild vegetables can cause symptoms such as spleen coldness and stomach deficiency. A few wild vegetables such as thistle and fishweed are slightly poisonous and may be harmful if eaten in large amounts. In particular, some wild vegetables such as ferns contain allergic substances, which may cause dizziness if eaten in large amounts. Therefore, you should not be greedy for eating too many wild vegetables. It is best to understand the nature, flavor and medicinal value of various wild vegetables and pay attention to your choices. Dr. Wang gave an example: The main components of dandelion are dandelion, dandelion sterol, dandelion picrin, pectin, inulin, choline, etc., which can prevent and treat lung, stomach and various tumors. However, dandelion is a wild vegetable that should not be eaten cooked. The best way to eat it is to wash it and eat it raw with dipping sauce. There are also some bitter wild vegetables, which are bitter in taste and cool in nature. They have the effect of detoxifying and dispelling fire. When eaten raw, they are bitter but sweet, refreshing and refreshing. However, excessive consumption can damage the spleen and stomach.
Some wild vegetables such as yam and mountain garlic are slightly poisonous. If they are not soaked, they may cause general discomfort after eating. These wild vegetables must be soaked in clean water for more than two hours to detoxify them before cooking.
In addition, it is best to pick and eat wild vegetables now. Wild vegetables that have been stored for a long time are not only not fresh, but also have greatly reduced nutrients and poor taste.
You should also be careful when drinking scented tea
In spring, flowers are in full bloom, including winter jasmine, roses, roses, etc. The reporter saw someone picking petals among the flowers in the community. He thought they loved flowers to satisfy their preference for flowers. After asking, he found out that they were picking petals back. Edible.
According to the determination of the food hygiene department, some flowers, like some edible plants, contain trace elements that are beneficial to the human body. Some flowers also have certain medicinal value, such as white chrysanthemums. But flowers are also "poisonous". Not all flowers can be used for cooking. If they are not handled properly, they can easily cause allergic reactions, poisoning and other adverse reactions. Therefore, before making floral dishes at home, you must find out whether the flowers you choose are edible. Furthermore, during the process of planting flowers, flower growers may apply a large amount of chemical fertilizers and pesticides to "stimulate flower growth". Therefore, do not blindly try new things without going through health quarantine and pesticide residue inspection and treatment.
There is a saying that "drinking various scented teas has beauty effects." Therefore, drinking scented tea has gradually become a fashion nowadays, especially among white-collar workers. However, Dr. Wang reminds everyone that many scented teas have side effects, and drinking them improperly will cause adverse consequences.
Ms. Li is in her late teens and is worried about her increasingly yellow complexion and increasing number of freckles. Last summer, she heard that drinking scented tea can whiten her skin, so she began to drink petals of roses, safflowers, chrysanthemums and other flowers as daily drinks in large quantities every day. However, soon after, she discovered that not only did the freckles on her face not disappear, but she also developed symptoms such as general fatigue and menstrual irregularity. She went to a traditional Chinese medicine hospital for treatment. The doctor believed that she had taken a large amount of safflower and asked her to stop taking scented tea. It didn't take long for her symptoms to completely disappear.
Dr. Wang said that many flowers can be used as medicine, but they all have certain side effects and they should not be consumed as health care products. For example, safflower can activate blood circulation and remove blood clots, but if used improperly, it can cause menstrual bleeding or cardiovascular and cerebrovascular diseases, and pregnant women can cause miscarriage; double flowers have the effects of clearing heat, detoxifying, reducing swelling and relieving pain, but people with weak spleen and stomach should not use it frequently; although chrysanthemum tea has It has the effect of clearing away heat and detoxifying, but it is not very suitable for those with yang deficiency constitutions referred to in traditional Chinese medicine. Scented tea should not be consumed casually in large quantities for a long time. It should be selected scientifically and rationally according to each person's specific situation under the guidance of a doctor.
Although wild vegetables are fragrant, they are afraid of "light"
According to reports, accidentally eating wild vegetables may cause dermatitis. A lady took her children on an outing after the Qingming Festival and picked some wild vegetables to cook home. The next day, all three members of the family had "skin reactions" of varying degrees, that is, they felt itching on the face, back of hands and forearms, swollen eyelids, ecchymosis, papules, etc. At first, they thought it was caused by sweating and sun exposure, but later Blisters formed, and the child kept scratching because of the unbearable itching. After rupture, erosive ulcers formed. When he went to the hospital, he was diagnosed with "vegetative solar dermatitis."
According to doctors, after some people take certain wild vegetables, their bodies are exposed to sunlight, which can cause this kind of dermatitis.
It is understood that this is a phototoxic disease. Although the true cause of the disease is still unclear, it has been identified that the patient's physical condition, consumption of light-sensitive plants, and sun exposure are the three predisposing conditions for the disease. Some data show that people with liver and kidney diseases, endocrine disorders, metabolic abnormalities, malnutrition or anemia are prone to suffer from this disease. The onset time is mostly concentrated between May and August. Young and middle-aged women are prone to it, and the male to female ratio is about 1:4.
Severe cases of plant-solar dermatitis often develop systemic symptoms such as fever, dizziness, vomiting, diarrhea and even coma. After the skin lesions recover, there is often pigmentation, which can subside after a few weeks. Deep ulcers will leave scars.
According to reports, since this disease is a phototoxic reaction, it is a non-immune reaction, and its intensity is more severe than that of a photosensitivity reaction. The clinical manifestations are similar to second-degree burns. Sun protection and light protection must be used during treatment.
According to literature, light-sensitive plants that can cause this disease include: gray cabbage, milkvetch, radish leaves, mustard greens, elm leaves, sophora flowers, amaranth, acanthus, figs, and cultivated vegetables such as cabbage, spinach, and rapeseed. , as well as psoralen, Pediculus, Agrimony, etc. in Chinese herbal medicines, there are more than 37 kinds of them in domestic statistics. These plants are rich in furanocoumarins and mostly belong to the Rutaceae and Moraceae families of the Umbelliferae family.
Patients who have experienced plant-solar dermatitis must fast from the plants listed above to prevent recurrence, and must also abstain from eating mud snails. They must also be careful in using drugs that can easily cause photosensitivity reactions.
