Eczema (or dermatitis as it is sometimes called) is a type of inflammatory skin condition which can affect all ages and can vary in its severity. In its mild form, the skin becomes dry, hot and itchy but in its more severe form, the skin can become broken, raw and bleeding. Eczema is not contagious but it can sometimes look unpleasant.
The word eczema means "to boil" and it affects up to ten per cent of the population. Dryness of the skin is the main problem associated with eczema and this dryness is aggravated by hot, dry conditions or extreme cold.
Eczema almost always begins in childhood, usually during infancy. Its symptoms are dry, itchy, scaly skin, cracks behind the ears, and rashes on the cheeks, arms, and legs. It alternately improves and worsens. During flare-ups, open weeping or crusted sores may develop from the scratching or from infections. Because the itching makes the eczema sufferer want to scratch, the skin can get broken allowing other skin infections to take a hold. Children suffering from eczema may also suffer from asthma and hay fever at the same time or one or both of these conditions may appear later.
The itchy feeling is an important factor in eczema because scratching and rubbing in response to the itching, worsens the skin inflammation and a vicious cycle of itch-scratch develops. The almost unbearable itchiness of the skin causes the person to scratch, which in turn worsens the itch and so it goes on. Itching is particularly a problem during sleep so the nails should be kept short and even cotton mittens should be worn to help stop the scratching.
The exact cause of eczema is not known although medical studies and research are on going. However, there are certain risk factors such as:
-- A family history of eczema.
-- A family history of allergies, including hay fever and asthma.
-- Contacts with irritants in the environment.
-- Abrupt changes of temperature.
-- Heavy physical activity that causes sweating.
-- Emotional stress.
-- Allergens such as house dust mite, animal dander, grass pollens and moulds.
-- Occasionally, allergic reaction to particular foods.
It is wise to treat the condition as soon as an outbreak occurs and a natural healing product is indicated to help eliminate the itching before the healing process can begin.

湿疹（有时候也称为皮炎）是一种皮肤炎症，可发生于所有年龄段，并且严重程度不一。其轻度表现为皮肤干燥，发热，瘙痒；重度表现为皮肤皲裂，刺痛并出血。湿疹不会传染，但有时看起来令人厌恶。

湿疹这一名词意为“沸腾”，在人群中患病率超过10％。湿疹带来的主要问题是皮肤干燥。炎热，干燥或极冷可以加重这种干燥。

湿疹几乎总是发生于儿童，通常在幼年时期。它的症状是干燥，瘙痒，鳞屑，耳后裂纹以及面颊，手臂和腿部的皮疹。患者时好时坏。在急性发病期，（病人的）抓挠或感染可引起浆液性渗出及结痂。由于瘙痒使湿疹患者抓挠患处，皮肤由此出现伤口使皮肤的其它部位感染。患有湿疹的儿童常同时患有哮喘和干草热，或随后患上哮喘或干草热（或两者都出现）。
