Psoriasis remedies are generally produced under poor medical conditions, and most of them are heard by the public, which may be misinformed, and the drug name, usage, dosage, indications and contraindications are all wrong. So these remedies can't give full play to their own curative effect. Moreover, there are individual differences in patients with psoriasis, and the situation of each patient is different, such as gender, age and physique. It is obviously unscientific to use the same prescription at this time, and it is unlikely to lead to serious consequences. The folk prescription of psoriasis is not useless, but we must be cautious and need to cooperate with the corresponding formal treatment to achieve twice the result with half the effort.
