Rosacea, also known as rosacea, commonly known as red nose or red noses, is a chronic inflammatory condition that occurs on the face. Most scholars now believe that follicular infection is an important factor in the development of rosacea, but it is not the only factor. Alcoholism, spicy food, high temperature and cold stimulation, digestive and endocrine disorders can also contribute to the development of the disease. First of all, we should pay attention to avoiding spicy foods that are too irritating in our diet, especially alcohol, cold and heat stimulation, and emotional and mental stress. According to a recent study conducted by the National Rosacea Society, the main triggering factors for rosacea include sun exposure, emotional stress, hot weather, wind, physical exercise, alcohol, hot baths, cold weather, pungent food, humidity, indoor heat, skin care products and hot drinks. According to Chinese medicine, rosacea is mostly caused by poor diet, heat accumulation in the lungs and stomach, steam and wind, and heat stagnation in the nose. Patients should promptly treat gastrointestinal diseases and properly deal with localized lesions and other parts of the body. Diet should avoid foods that promote facial skin redness, such as chili, mustard, raw onion, raw garlic, wine, coffee and other stimulating foods, and eat less oily foods, such as animal oil, fatty meat, fried foods, pastries, etc., to reduce the secretion of sebum. Eat more foods rich in vitamin B6, vitamin B2 and vitamin A and fresh fruits and vegetables. You can also take methotrexate tablets that can kill worm mites, 0.2 grams each time, 3 times a day for 2-4 weeks, and those with serious conditions can go to the hospital for surgery. The treatment of rosacea is more troublesome, but it can still be controlled and treated through treatment. The key point in treatment is to try to avoid the symptoms that trigger rosacea. Usually, patients can also help a lot by improving their diet and living, and the main aspects include the following: 1. Eat a light diet, eat more fruits and vegetables, forbid stimulating foods and drinks, and correct constipation. 2, should minimize sun exposure, wear a hat with a wide brim, use a shade containing at least 15 solar protection factor. 3, should avoid contact with irritating substances, but also use soap-free cleansers, avoid the use of astringents and abrasives. 4. A rosacea trigger diary should be kept for 2 consecutive weeks to note down the possible causes of flare-ups or exacerbations of the condition so that these triggers can be identified and avoided in the future. Medication for rosacea Mild rosacea patients can be controlled with topical medication alone, and for slightly more complicated cases, oral and topical medication can be used at the same time at the beginning, and after remission, patients can often stop taking oral medication and use topical medication alone. After remission, the patient can often stop the oral medication and use the topical medication alone. Occasional flare-ups may be followed by a return to oral medication. Metronidazole (Methotrexate): Metronidazole is the most commonly studied topical medication for rosacea and is currently available as a cream, gelling agent, and lotion. Metronidazole is an isopyrazole with antibacterial properties. The exact mechanism by which this drug can improve the symptoms of rosacea is not known and may be related to its anti-inflammatory and immunosuppressive properties. It is also effective in the treatment of papules and pustules, reducing erythema of eruption. However, it usually has no anti-capillary dilation effect. The use of metronidazole is easily accepted by patients because of its ease of use and mild side effects. Just over 2% of patients report stinging, dryness, itching, and burning sensations after use. Sulfacetamide sodium: Sulfacetamide sodium has also been used for the topical treatment of rosacea. However, this type of drug should be avoided in patients who are allergic to sulfonamide antimicrobials. There are several different types of sodium sulfacetamide lotions available. Clindamycin (clindamycin, clindamycin): Topical clindamycin preparations, although not approved by the (US) Food and Drug Administration for the treatment of rosacea, are effective in water-based gels and lotions for rosacea and are easily tolerated by patients. Azelaic acid (azelaic acid): Azelaic acid, which is known for the treatment of acne vulgaris (commonly known as “pimples”, “acne”, and “rosacea”), can also be used to treat rosacea. In a randomized comparative study in patients with papulopustular rosacea, scientists compared the efficacy of a 20% topical azelaic acid cream with a 0.75% metronidazole cream. After 15 weeks of treatment, both drugs achieved the same efficacy, with both significantly reducing the papules and pustules on the patient’s face. Systemic treatment of rosacea More severe cases of rosacea require systemic treatment. Systemic treatment usually begins with oral antimicrobials such as tetracycline (250-500 mg twice daily), doxycycline (50-100 mg twice daily), or dimethylamine-tetracycline (50-100 mg twice daily). The internal prescription for rosacea: 1, take 9 grams of silver flower, 15 grams of Zhi Mu, 30 grams of raw gypsum into a pot, then add 500 ml of water, decoct together, take 30 ml of the juice and 60 grams of round-grained rice and cook into a porridge, eat every night before bed. 2. Fry the appropriate amount of Junzi in an iron pot with a gentle fire until it has a slight aroma, leave it to cool down, and then soak it in sesame oil for 1 week. Patients should take 3-5 pieces of Junzi seeds with warm water every night before bedtime for one week. 3, take loquat leaves (remove the hair, roasted and dried) and grind it, mix it with tea to 3-6 grams, take it 3 times a day, it can effectively treat lung fever, especially effective for rosacea.
