This post has been brought about through reading many of the eczema threads on this board.
The general advice given on here is to slap on emollients and hydrocortisone, which is a powerful steroid. Emollients are all petroleum based and full to the brim of nasty chemicals, which can exacerbate the problem. Hydrocortisone can cause the skin to thin if used too often.
The other issue I have is that hardly anyone seems to tackle the cause of eczema. It is nearly always caused by an allergy to something - the common causes are dairy, wheat, washing powder, creams, central heating, pet allergies and so on. GP's never want to get to the cause of the eczema and just dole out chemicals.
The link between dairy and eczema is proven, and yet few people suggest leaving it out of the child's diet, and when it is suggested, people worry about making such a 'drastic' change to their diet. FGS half the world survives quite happily without it.
Very few people suggest natural remedies such as organic creams, perfume-free washing powder (don't use conditioner!), or changes to diet.
RANT OVER. And sorry to those who have suggested the above and whose posts I have missed.
