There are many examples of patients suffering from various skin diseases who have been victimized by prescriptions. Recently, we have seen another patient who has been victimized by “prescriptions”. Patients with psoriasis may have noticed the advertisements for the treatment of psoriasis in various media and even all over the streets, some of them claiming to have biased prescriptions, ancestral secret recipes and even boasting that they can cure the root and so on. For these claims, there should be a correct view. 1, the treatment of psoriasis is still waiting for further breakthroughs in the world, from traditional medicine to modern medicine have not yet solved the so-called “root” problem, to judge whether the prescriptions are credible depends on whether they have a factual attitude. 2, should see the reason why this kind of advertising has its market is to seize the patient’s long-suffering, disorderly psychology. There are also some wandering doctors who take advantage of people’s psychology of believing in Chinese medicine, under the banner of Chinese medicine to spoil the reputation of Chinese medicine, is very harmful. 3, is also the most fundamental point, most of the ads appear is driven by economic interests. Their fundamental purpose is to make money from patients. Therefore, we remind the majority of patients not to fall for the “bias”, to borrow a fashionable saying – do not be obsessed with bias, bias is only a legend.
