Follow some tips by Ilchi Lee for indirect moxibustion with ginger:-

1.    Slice a 1/5-inch-thick piece of fresh ginger. Punch numer ous holes in it and place it over a point.
2.    Roll the mugwort or “moxa” into a cone shape approxi mately the size of a grapefruit seed or bigger.
3.    Place this cone on top of the ginger slice.
4.    Light it with incense and leave the moxa cone in place until it burns out.
5.    Repeat this four more times on the same spot. As you repeat the procedure, you do not need to replace the ginger slice.
