New skin 1st. Then clove powder?
When I did this , it stopped the itch, and pain of the nodules, reducing them to scar tissue.
Even the large patch areas disappeared.
It formed a hard shell over the nodule, which if just the new skin was applied, it would just itch.
The clove powder will deaden the nerves, and kill the itch and pain.
Works well on burns as well.
If the nodule is just a scab, it will stop itching, and then new skin alone will treat it.
If the scab still itches , reapply the new skin, and clove powder.
Remove new skin as directed, if needed .
