From the herbal corner:
for influenza the best advice I can offer is Dr. Christopher's favorite - red raspberry leaf tea. Lots of it. And lots of water. Don't get dehydrated.
If you have sore throat along with it, a good cup of warm water with a spoonful of salt is a great gargle for that. Several times a day. You can even use it by taking some in your mouth, bending your head over a bowl, and then letting it run out your nose. Ick, I know. Make sure you have kleenex near to hand. Will clear your sinuses.
Add a hydrogen pyroxide ear wash out - three times each side with a towel on your shoulder for the rinse. And do it sitting down2 or 3 times a day. Sore throat should be history.
If there is lots of mucus, comfrey leaf tea is a several thousand year old remedy for that.
If it's gone to bronchitis or worse - raw garlic - a small piece of a clove crushed on the end of a spoon with honey and a touch or lemon juice to cut the garlic acid is the best herbal antibiotic I know of. Every two hours to start, then four, then 3X a day, then twice. By the end you might be able to take a whole clove. Better than a flu shot. Best if you can find organic, as studies show that more of the 'good stuff' has been found in organic vs. the usual. But if the usual grocery store garlic is all you can get, it's STILL the best.
And from the point of view of an old curmudgeon broad such as myself, nothing beats a good porta potty. Thetford rules. I don't use the toxic blue stuff, tho. Dawn blue works fine, I've found - and in the Florida heat, too. I've heard some like Fabuloso purple.
