The way I used is: grind it then add ACV, let it stand around one hour to be a soft paste, take internally one teaspoon 2 times a day (before or after meal).
I used this paste externally for skin fungus especially feet fungus and it gives magic results and cure it forever.
Don't grind alot of black cumin, just prepare for 2-3 days every time and keep it tightly in a jar because it oxidize by air.
