I have had great success using medical marijuana. It stops chilblains in its tracks and greatly speads up the healing. It has two years now that I have used medical marijuana for treating this. The next flair up I am going to try a hemp extract of CBD which has no THC so there is no high from using it. This will tell me if it is the CBD or the THC that is so very effective. Also it stops the pain. No need for painkiller with this.
