What about using Zicam swabs in the nose? They are used to stop a cold or reduce the severity of a cold.
Haven’t heard anything about the effectiveness of Zicam, so I can’t honestly answer your question. I can only offer up what doctor Zelenko recommends, and had used with significant success. 🙂
Oral zinc supplements might benefit people with low levels of zinc. Taken soon after cold symptoms appear, zinc might also shorten the length of a cold. However, don't use intranasal zinc, which has been linked with the loss of the sense of smell.
The above was from The Mayo Clinic
Without smell, you also do not taste food correctly either, from what I have heard. Hope that helps. 🙂
