I still use wonder dust and proudsoff, and will in the future. Hell of a lot better than the outcome of uncontrolled proud flesh. Another alternative is pressure wrapping but the stuff seems to have an evil intelligence and never be in a location which is readily wrapped.
If you have any references which document against the old remedies, I'd appreciate your posting.
Good reference on proud flesh in general: http://www.thehorse.com/ViewArticle....=181&src=topic
Note that wrapping appears to be the primary treatment in this article with steroid application if needed. Also note that, while they say that copper sulfate (the primary active ingredient in proudsoff and wonder dust) is no longer recommended, they go on to say it can be useful. IMO, the issue is overuse, which can definitely cause damage by itself - "caustic" is by definition hazardous and can "burn" flesh. As noted in my earlier post, I still find it useful but appreciate the caution.
