I don't think you should take black salve internally, especially if it is formulated for external use only. Use Google to search for it and you will find several places that sell tinctures and pills. You can also buy it powdered and make your own capsules, which is very potent. It can produce dramatic die off symptoms and make you feel very ill, so don't use much, just a tiny bit and slowly increase until you find the right dose for you. I wanted to get rid of the pain and misery as quickly as possible, so my cue was to increase the dosage until I felt a little nausea when I took it. I would then stay at that dose level until the nausea went away, then increase the dose to mild nausea again. The nausea would only last about 15 minutes. If I increased too much, I would throw up. It will also make you dizzy when the liver is clearing. Because I had been on it for 11 months, I was a bit worried about quitting cold turkey, thought it might be necessary to taper off, but there were no withdrawal symptoms at all.
