My husband and I have decided to do these things every day (or as near as possible), in order to give ourselves a growling good immune system and to combat whatever flu bugs might accidentally wander into our environs.
Vitamin C (1000 mg base amount, more if needed)
Vitamin D3 (1000 - 50000 mg base amount)
2-4 droppers of elderberry extract (more if needed)
Multivitamin/mineral mix (Michael takes this; I skip it as I prefer to get my nutritional needs met via eating wild plants. I just go outside an nibble on whatever I find--wood sorrel, plantain leaves, yellow dock leaves, gnaw on some sassafrass leaves, a couple of spice berries here, couple of wild grapes there, the classic nibbler diet)
Clove garlic a day
Kimchi at least one serving a day
The usual good diet of meat with veggies galore, a minimum of sugar or white flour products, very little to none processed foods
If necessary/as needed
Goldenseal/Echinacea extract with a Cayenne extract for booster
And getting out into sunshine, getting some exercise, swinging our arms, praising God's gifts. The last mentioned is without a doubt the most important, praising God and being grateful. And if by chance we get a flu--we normally don't, nor have we ever taken flu shots, then we'll live with it and let the elderberry extract deal with it.
Another fairly important element in this is to avoid those who are ill. Be very careful when you go to stores, wash your hands so often you'll feel obsessive/compulsive, all the usual stuff.
I put by a lot of elderberry extract this year. I filled quart jars 1/2 to 3/4 full with elderberries, then add vodka to top it all off. The six weeks I usually allow for extracts is nearly over. I have offered the extract to everyone in the valley, and I hope they'll use it and wisely. I don't charge $$ for this, but donations will be accepted to cover the cost of the vodka.
I've also laid in some OTC pharmaceuticals--mucinex and sudafed in particular. Someone who'd already had the swine flu recommended those. So, on a just in case basis, I got a few of those. We also have gloves and masks, and somewhere I have a whole biochem suit (complete with gas mask) that someone once gave me. It'd make a great Halloween costume...
So that's our basic flu protocol. I don't know if we'll need it, but it can't hurt to give your body extra nutrients for combatting illness. It's very important also to detoxify--try to get rid of the crap in your system, fast one to three days every once in a while, take hot baths and sweat out toxins, don't eat processed "food" poisons, and move around a bunch.
If anyone has other/different ideas, I'd be glad to hear them. Thanks,
