I work from the impression that any MW frequency will do the job of applying the effects of that substance. It doesn't mean that it will remove or negate them.
To eliminate a parasite, you probably will want to use a BP or DNA frequency of the parasite which is calculated using different parameters. I'm not sure how one obtains chemical components for specific parts of a parasite either, or how that would affect the parasite.
Perhaps Manuel could shed more light given that he developed the preset and calculator that goes with it, in case I misinterpreted your meaning.
