—Thank you for the opportunity to respond to the concerns of Mr Katzman and Dr Rosner concerning our recent work with the Rhinotherm. As we noted, many people experience temporary amelioration of symptoms associated with the common cold following steam inhalation. Our intention was to ascertain if steam inhalation would inhibit replication of virus and provide lasting benefit; we found it did not. It was not our intention to condemn the use of properly maintained vaporizers and humidifiers and thus "endanger lives."Rosner reminds us that we did not mention the beneficial effects of chicken soup in relieving cold symptoms, but we felt that such a well-established remedy didn't need further justification. We continue to advise patients with colds to use vaporizers, chicken soup, and anything else that they believe helps them feel better as long as the remedies have no serious side effects.These letters were shown
