These are my tips and I am not a doctor, but these are things that have definitely worked in our home time and again!!! I really swear by them. These tips are mainly to fight colds: sore throat, coughs, etc.
The earlier you start these when symptoms appear the better.
1. Squeeze half a lemon, add enough honey and water to make it palatable. Drink several times a day. The sooner you do this after the first hint of sore throat or scratchy throat the better. A hot cup of water, with a whole squeezed lemon with honey is nice alternative, hot lemon tea. It's good.
2. Start taking echinacea with the first symptoms of cold or flu. This is an immune booster. It is known to shorten the length of illness. Studies at the UofW, have shown this. (Wish I had a link to the study, James, can you find one?) Take no more than 2 weeks.
3. Garlic is a well known anti-viral, anti-bacterial. Take as raw as you can. I make garlic oil and sneak into the shot glass of echinacea juice for my kids. Yes, the older ones notice the floating but it's medicine...put a little honey in it and they won't complain too much. "A spoonful of sugar helps the medicine go down."
Some other tips I've found to work:
If you child complains of ear pain, make or get some garlic oil and put a few drops in the complaining ear. In no time at all the pain is gone.

The healthier you are inside the easier it is to fight any bugs trying to make their way in.
Again, I'm not a doctor, these are tips I've found after researching on my own. You can do some research as well: Herbal Remedies for colds. Yes, it is not "orthodox medicine" but after trying, I've changed my mind.
