A lady aged about 30, suffered greatly from a carbuncle  on the back of the neck;
She had applied many domestic medicines and obtained no relief.
The tumefaction seemed destined to suppurate.
It was mottled bluish and the pain was intense, knife-cutting and burning.
She was sick at the stomach to vomiting, and at night she was delirious. Her eyes were staring and there was some fever ; the tongue was foul and the breath fetid.
There was great tension in the scalp and muscles of the face. She begged for morphine to “stop that burning and cutting.
” Tarantula cubensis 12x one dose produced quiet immediately and the angry looking tumefaction failed to complete its work ; it did not suppurate.
The discoloration was gone in two days, and the hardness soon disappeared also.
She regained her normal state very rapidly, and she said to me a short time ago that she had never had her old headache since that swelling left her, showing how deeply the medicine affected her whole system.
If a part is mottled (Lachesis), bluish, growing dark, with those symptoms, Tarantula cubensis must be the most appropriate remedy.
