this summer, the temperature is high, the humidity is high, and there is a lot of rainfall. It is suitable for mosquito breeding. With high mosquito density, it is inevitable that everyone will be bitten by mosquitoes. Because the saliva stabbed into the skin after mosquito bite contains exogenous protein, it will trigger the human body’s instinctive protective mechanism and form a local inflammatory reaction, that is, an allergic reaction, so it is easy to produce red pimples after being bitten by insects. The characteristics of this rash are different from other allergic diseases. Everyone’s constitution is different, and the duration of symptoms and the degree of allergic reaction after being bitten are also different. Let’s follow and learn about it!
For common symptoms such as redness, swelling and itching caused by mosquito bites, we can use many methods to reduce discomfort:
can be immediately applied with strong soapy water at home. This is because mosquitoes secrete an organic acid & mdash& mdash; Formic acid, this substance can cause muscle itching. Soap contains the sodium salt of higher fatty acids, which is alkaline after hydrolysis. The OH – and H + of formic acid are neutralized into H2O, which can quickly eliminate itching.
It can also be applied with topical drugs to relieve itching symptoms:
1, cooling oil, etc.: ordinary mosquito bites and insect bites, and Fengyoujing and cooling oil can be used, which are both effective and less irritating to the skin. However, the skin around the eyes, nostrils, lips, vulva, anus and near the junction with mucous membrane should not be used. It is forbidden to use it at the exudate and wound.
2. Calamine lotion: calamine lotion contains calamine and zinc oxide. It has astringent and protective effects. It can reduce inflammation and itch. It mainly treats eczema in children. It can also reduce inflammation and clean up wounds caused by strong allergy or suppuration caused by mosquito bites.
3. Erythromycin eye ointment: if the bitten place is close to the eye, it can be coated with erythromycin ointment to prevent infection.
4. In addition, hormone ointments such as mometasone furoate cream (alonson) and compound beclomethasone propionate camphor cream (Wuji cream) can be appropriately selected, but it is best to apply it on the affected area slightly or thinly to avoid large application, and it is not suitable to use it often. The skin areas with thin and tender skin and rich blood flow such as armpit, neck circumference, popliteal fossa (rhombic fossa behind knee) and thigh root of infants and adults should be used with caution. It is best to consult a doctor, otherwise excessive absorption may occur and adverse reactions.
5. Liushen Pill for external use. Liushen Pill can not only be taken orally to treat sore throat, but also be used externally to reduce swelling and relieve itching. Usage: take 10 Liushen pills, use a little cold boiled water or rice vinegar, take a spoon of Zhonghua powder, apply it for four weeks, and keep it moist several times a day until the swelling subsides. Do not apply it again if it is red, swollen, purulent or worn out. After 1 ~ 2 days of general medication, the patient’s redness and swelling decreased and the pain and itching disappeared. However, it should be noted that; It is forbidden for pregnant women and those who are allergic to this product, and this product contains musk. Athletes should use it with caution.
6. Repeatedly wipe the mosquito bite with watermelon skin to stop itching, and apply aloe juice to the affected area to stop itching.
7. Take a small amount of Huoxiang Zhengqi water and apply it to the bitten place for about half an hour. The itching can be reduced or eliminated.
8. Take a little toothpaste or crushed mint and apply it to the bitten place. You will immediately feel cool and comfortable, and the itch will disappear.
9. Take one or two aspirin, grind it into powder, mix it into a paste with cold water, and apply it to the affected area, which can also reduce or eliminate itching.
10. When drinking porridge, you might as well wait for a few minutes. After the surface of porridge has solidified into a film, apply it to the mosquito bite, which can also stop itching.
It should be reminded that when applying the medicine after mosquito bites, in order to facilitate local absorption and relieve itching, it is recommended to rebound the affected part with fingernails to a slight red and then apply it thinly and spot. It is not suitable to scratch to avoid skin damage. Hormone drugs generally do not exceed 2 times a day. If there are many application parts, it is best to wash them before going to bed.
once severe insect bite allergy occurs and the above methods can not alleviate the symptoms, the patient should go to the hospital for treatment. Oral antiallergic drugs are the first choice. At present, the commonly used antiallergic drugs in clinic are the second-generation antihistamines, which are a kind of long-acting drugs. They only need to take one tablet a day and absorb quickly after oral administration. They can quickly improve allergic symptoms within 15-30 minutes. At the same time, there are few side effects and almost no obvious anticholinergic and sedative effects. The commonly used drugs are loratadine Cetirizine, mizolastine, ebastine, etc., especially kairuitan (loratadine) has little side effects, and can also be used safely in children. If combined with strong corticosteroid tincture and ointment for external use, it can usually quickly improve the clinical symptoms of patients.
In addition, we will introduce a self-made mosquito repellent kit. There has been & ldquo; Wearing a vanilla bag is not afraid of five pests & rdquo; That’s right. This principle is the same as many people used to put a handful of Artemisia argyi in front of their homes to repel mosquitoes. Put mugwort leaf, clove, Angelica dahurica, perilla leaf, mint, patchouli, Acorus calamus and honeysuckle 10g each into the medicine bag, hang it indoors or wear it with you, which has a certain mosquito repellent effect. From the perspective of traditional Chinese medicine, Wormwood Leaves and Acorus calamus have the effect of repelling mosquitoes and insects. Modern medical research has also proved that these drugs contain a large amount of volatile oil and have antibacterial and antiviral effects. However, the hanging of mosquito repellent Chinese medicine bag is particular, and pregnant women and people with allergic constitution should use it with caution.
