Marshall's RX ingredients are: Balsam, Camphor USP, Oil of Origanum, Oil of Rosemary, and Corn Oil.
Vicks VapoRub (VVR): Camphor (4.8%), Menthol (2.7%) and Eucalyptus (1.2%). According to the authors of the study (Abanses, Arima & Rubin, 2009)"Menthol is thought to be the primary agent responsible for the sensation of decreased congestion by activating trigeminal cold receptors (p. 147)." Ironically what the authors found was that although healthy human subjects 'perceived' improved airflow the objective measures showed none after inhaling VVR. The bulk of study refers to Vicks VapoRub as the combination of these 3 ingredients. The authors concluded that ".... although VVR can fool the brain into perceiving increased airflow by activation of trigeminal cold receptors, the active ingredients are ciliotoxic and mildly proinflammatory, increasing mucus secretion while decreasing mucus clearance (p. 147)."
My personal view is because ferrets are known to have sensitive respiratory systems, I would be reluctant to use any sort of inhaled substance.

[Moderator's Note (SDC): Thanks, Tressie! Isn't menthol primary
active ingredient in peppermint oil? Yes, okay, here it is:
