This is not Craig Caton's company....it's a knockoff. I returned a product to them....it took almost 2 months of constantly reminding them that they had not refunded my money like they kept saying they had to FINALLY get the refund. Only after I said I was going to file a complaint with AMEX did the refund show up the very next day!!
And I remember now too, it took a very long time to receive the product....they kept saying it was so popular they had run out....but they charged my CC the day I placed the order. I do a lot of business online and this is the first and worst time I've had problems with a company.
Be very careful with what you order from them. With this kind of service I would questions the quality of anything they sell.
RE: black salve....if it's prepared properly it will work as it should....will grab a cancer and do its thing or if there is no cancer there, it will do nothing. If you used a bandaide over it, the irritation you're seeing is from that and not the salve.
