the black tar must be separated from the medicine by adding water & low heat until it separates into clear organic acids & atomized mineral salts.

i just bought all the purest ingredients and make my own.

bushcraft chemistry can make it, its the smoke of the fire, those are the medicine going up in the smoke.

normally the smoke is not combustible without a heated secondary oxygen intake.

low heat Pyrolysis is how to capture it.

but it must be relatively clear liquid, any yellow, black or brown is toxic soot & hydrocarbon, non-water soluble waste.
