Anyone seen this ??

There are some topical treatments of Chinese/China Origin that contain steroids in quantities not allowed in UK or Europe, or that claim to be "all natural" but in fact contain undeclared steroids and other pharmaceutical agents. That could be why they can initially seem to be a miracle cure. eg YIGANERJING https://www.psoriasis-association.org.uk/news/yiganerjing-cream-found-to-contain-steroids If you type yiganerjing into the search on this website you can also see several threads about it in these forums.

Are you looking for something without steroids? I've been using this natural cream with no toxic chemicals in it and it seems to be doing the trick for my legs.
