Spanish term (edited): Cómo quisiera arrancarte la enfermedad con el calor de mis manos.

OR:

"from your sickness" instead of "from this disease", depending on what it is that she has....

"From the clutches of..." or "from this affliction" might work if this is an 18th or nineteenth century text, and you are trying to capture the flavor of the English that was used in those times.

I think that Nedra has the right idea in terms of translating in terms of "rescuing the sufferer" rather than "removing the illness" [the original clearly indicates the latter] but I don't think either "rip/tear the illness" or "wrest you from the clutches" really work. (But again, if you want to use archaic language, then "deliver from the clutches" would perhaps work.

Suerte.
