Some sufferers may find that the reddish patches fade away after the treatment; there are sufferers have not got any treatment, the reddish patches fade away by themselves too. We call them clinical recovery. But the clinical recovery doesn't represent that the disease has been cured completely.

(1) The pathogeny of psoriasis hasn't been clear, generally consider that the disease is lead by outside diathesis on the function of heredity. There has been no valid measure to the heredity now. There are many kinds of outside diathesis and different for each specific sufferers, some sufferers even no obvious nosogenesis. Some nosogenesis can be prevented and no measures against some others. So pathogeny can't be eradicated fundamentally even though the reddish patches fade away. Along with the changes of outside environmental, the disease may relapse when possess corresponding conditions.

(2) The clinical research discovers that even many sufferers come to a clinical recovering, but its immunity and tiny circulation haven't been recovered. There is mutual deposit covered on the scarfskin, T lymphocyte still has deficiency; the tiny circulation hasn't recovered normal even got some improvement. To say on this hand, clinical recovery is just a temporary phenomenon.

(3)From the point of view of clinical research, clinical recovery only named catabatic and can't consider it deracination. Because psoriasis is a chronic and repetitive dermatosis, it can be cured or alleviated with treatment. Some sufferers may not recrudesce more than 10 years or even 20 years, some may not recrudesce in all his life, but the possibility of relapse exists still, nobody dare to affirm that it won't relapse for ever.

Based on the fact that psoriasis can't be cure completely, so prevention and prevent relapse seem to be particularly important.

Too much sunbathe may get the disease worse. Mechanical stimulus, such as trauma, scald, operation, vaccination and get in touch with chemical, can induce tetter on the affected part.

There is report that tetter increases much after infection, commonly see as angina and tonsillitis. These sufferers can get good effect by use of effective antimicrobial. Tonsilar sufferers can improve the disease by exscind tonsil.

The change of physiology or psychology is one of the influencing factors. The former is particularly seen for female, when the female in menses, childbearing or lactation etc, the disease may become worse. The elders often companied with other medical diseases, not only the skin is difficult to cure but also the treatment effect isn't good. The companied diseases affect the proceeding of the normal treatment. In addition, keeping mental healthy is become more and more important. There are many examples that the disease turns worse by strain, overmuch tiredness, dumps, insomnia. Among the adult, psychic factors has became the chief one. Harmful habits such as drinking and piquant food are not to be neglected.

For the general sufferers it is particularly worthy to know that once you stop to use the medicine in course of the acute time, the disease may became worse, even may turn into pimple type or red skin disease type, result into serious result.

Although the psoriasis may relapse or become worse after cure, as long as the sufferers take care of the daily life it also could reduce to relapse or alleviate the condition,

For the patients in bad condition, it needs collective efforts, and to get the condition controlled at the most light degree. When the squama fades away you shouldn't stop the treatment at once, and you'd better continue to treat for period of time.

(5) The patients had better not drink alcohol, including every kind of alcohols, only a little beer may result certain troubles, and you can adopt preventive treatment under the guidance of the doctor.

Do the psoriasis patients need to avoid certain food?

We can't live without diet and we obtain every kinds of nourishment from the diet. The primary meaning of nourishment is maintain life and healthy. For getting the sufficient nourishment, we need balanceable diet. But, there are many reports about that the diet factor causes the psoriasis became worse, some doctors also have the sufferer avoid certain food, it brings the sufferers much stress and many inconveniences on the daily life.

The egg is a complete organism, with every substance that need for a young chicken. Another helpful food is fish, with low fat and sufficient protein. The fish oil enriches fatty acid and it also can be used to treat psoriasis. In addition, do not forget the bean product with low price and high quality, the fresh and tasty milk is also a good choice for the sufferers.
Then, vitamin also can't delete from the patient's menu. The data shows that psoriasis patients lack many kinds of vitamins, the doctor sometimes let the sufferers take some vitamin capsule. As well known, fresh fruit, crud bean, corn and the animal's liver all contains abundant vitamin. But we must be notice that vitamins may be spoiled if boils with a long time.

Now, let us to see which food do the sufferers should notices. Many sufferers were told that they should keep away from violent wine, strong tea, coffee and stimulating food. Many reports confirmed that they are really disadvantageous to psoriasis patients. But some people may much like some of them, it may bring them tremendous psychological stress if don't let them regale on, and it is disadvantageous to the cure of psoriasis, then the sufferers can treat with personal condition.

Lack of multiple biological elements can result in your nerve in tense state and the immunity decline. Finally, the sufferers can accord to own experience, get rid of the food that affects the state of psoriasis.

So, we suggest that the sufferers eat more beneficial food. First ,the food must with low fit and high protein, replace beef, mutton with chicken and fish; Then, guarantee ample vitamin and every kind of biologic elements, replace alcohol with fruit juice and drink herbaceous tea instead of coffee; Finally, you should notice the method that food processed, you'd better eat fresh vegetable instead of cooked and eat more coarse food grain.

When you adopt the suggestion above, you will discover it is a valid regimen, it can protect you away from cardiopathy, cancer and give you a long life.

Why the patients benefited much from eating fish?

As we all know, the essential fatty acids must supply directly from the food, we can't synthesize them in our body, and most of them mainly root in ocean fish.

Lots of patients ask the doctor that “Can psoriasis take place on the face?” It is clear that they worry psoriasis has influence on their face.

Theoretically speak, psoriasis can take place in the each part of the body, but usually on the scalp and limb, and often symmetry distribute. When suffer every kind of inducement, then the disease may easily go into action again and again. Such as the external injury, shock, infection, endocrine, weather factor, and nervous can makes the disease serous. Usually when the disease go into action, the face would appear erosion sometimes and the shape is red papula with the size as nail. That is say the erosion is small and not clearly to see, so it doesn't influence the facial appearance very much and the patients don't feel heavily stress. And that, the typical psoriasis patients' skin usually covered with thick scale, so the clothes may be easily polluted and bring many inconveniences to the patients. Because the patients wash face everyday and expose to the ray, so the scale is very thin or even no. The common says, the face is the sigh of people. So, we should prevent every induced factors at ordinary times, such as external injury, shock, infection, endocrine, weather etc. Even though tetter appears on the face, we should under the instruct of doctor, with properly treatment, the tetter can be controlled quickly and fade away gradually. Avoid by all means, we shouldn't take the medicine by ourselves.
