limits of cds?

The cds has advantages in some internal problem, because it travels in the blood, but as for something external it has limits I suppose, for example as soon as it is some affection in the skin by some virus, as the hpv or the herpes, since it evaporates, it seems more convenient to use some ozonized oil or photodynamic therapy.

I interpret the dmso as an "amplifier", as it allows a greater penetration of cds as I understand, I do not know if it would be valid to first spray the dmso on the skin and then apply the pure cds.

I accept corrections.

DMSO is called a carrier, so I would first apply CDS topically, then DMSO on top.
