I believe many friends already know that psoriasis is a common chronic skin disease, which is characterized by repeated layers of silvery-white dry scales on erythema, and obvious bleeding spots appear after scales peel off. Ancient Chinese medicine called it "white furuncle", and ancient medical books also called it psoriasis. It is characterized by papules and erythema of different sizes, with silver scales on the surface and clear boundaries, which are common in scalp, limbs and back. There are more men than women. Psoriasis is easy to recur or worsen in spring and winter, but it is relieved in summer and autumn. In addition, the city's wild advertisements are also called "psoriasis". Generally speaking, the early symptoms of psoriasis are mainly reflected in the following two aspects: 1. The initial lesions are usually red envelopes or brownish red spots or maculopapules with dry silvery white and grayish white scales. At first, the scales were easily scraped off. Once scraped, the scales flew off one after another, showing a reddish translucent and shiny film. There are small bleeding spots in the shape of a sieve, just like dew. 2. After that, the rash gradually expanded and worsened, and some spots separated from each other to form plaques, with obvious infiltration at the bottom, clear edges and inflammation around them, which were dripping, coin-shaped, map-shaped, disc-shaped and oyster-shell-shaped. Generally, severe head injuries are more common. In terms of treatment, I believe many friends have already understood it. Psoriasis has been treated for a long time. At present, most oral drugs used to treat psoriasis belong to immunosuppressants, which have adverse effects on normal immune function. If the drug is used blindly for a long time, the resistance of patients with psoriasis is low, which seriously affects the treatment. Therefore, if you want to cure psoriasis, the key is to prescribe the right medicine and choose drugs reasonably and accurately according to the patient's own specific situation. Some drugs, such as oxybecan, have a significant effect on psoriasis. Their effects directly act on the surface layer of skin and blood from the outside to the inside, directly hit the source, differentiate epidermal cells, and immediately stop itching and sterilize. In addition, according to the dialectical analysis of traditional Chinese medicine, psoriasis has the image of "blood dryness, blood heat and blood deficiency", while from the perspective of western medicine, it is caused by excessive proliferation of keratinocytes and various biochemical and metabolic disorders. Therefore, all foods that nourish blood, cool blood and promote blood circulation, or inhibit cell DNA synthesis and improve microcirculation are beneficial to psoriasis. For example, fruit drinks such as ebony and grapefruit have the functions of clearing away heat, cooling blood, quenching thirst and promoting fluid production. They are not only rich in vitamins and trace elements, but also can reduce blood lipid and blood viscosity. Pomelo and Huyou have been proved to have the effect of effectively inhibiting cell division, which is a summer prevention and treatment.
