Your suggestions are fine for long term, but for an immediate crisis situation, use CS and use a nebulizer. It doesn't matter what type of CS you use as long as its a 10-20ppm or homemade, even 3-5ppm has value. I make my own CS with a silver puppy. The person in the video uses the same protocol that I have used over three years when I feel a cold/flu coming on. I have not been sick in over 3 years.
Its very nice that an independent person says that the same protocol that I am using works for swine/hybrid flu. Again the most important part is to use a nebulizer to get the CS into your lungs.
