Grandma's #1 remedy: Wash your hands well.
Grandma's #2 remedy: Leave fresh veggies on the table for snacking before big meals (I suppose it encouraged pooping, it certainly prevented overeating and indigestion)
Grandma's #3 remedy: Sensible warnings, particularly "If you eat too much sugar and get sick, I'll take you back home to your parents."
Dad's #1 remedy: Sick people need lots of fluids and sleep, and as little stimulation as possible. First water, then tea with honey (not for babies) then more water. I still use this routine when I need to get better in a day, though with less forced drinking. The boredom makes going back to school/work look good pretty quickly.
Interesting vitamin store remedies:
Fish oil – Cheap and helpful for joint pain, almost replaces glucosamine & chondroitin
Ginseng – perhaps some types of ginseng work for someone.
Green tea – used tea bags certainl helps inflamed skin look much less red, and temporarily handle itching.
Internet remedies – Raw Honey – On skin, it certainly doesn't hurt, but I haven't proven it helps. I haven't tested it on serious wounds/burns, but in small studies raw honey is an often effective last resort. (The small chance of botulism is worth noting, particularly in babies and immunosuppressed people)
Yogurt – Certainly useful for the digestive tract, and at the very least, pretty harmless elsewhere. A mild base.
Lemon – a strong enough acid to be quite useful, probably antibacterial, safe for most uses (particularly if diluted, which most home remedies suggest).
Vinegar – Widely used in cleaning, eating, stings.. strong enough to be useful, mild enough to be pretty harmless.
Hydrogen Peroxide – a strong enough acid to be very useful, if somewhat worrying (there are enough stories about people taking it internally without watering it down). Breaks down quickly, so no worries about lingering in the system.
Bananas – great for muscle aches after a workout.

There were some very good home remedies both in the article and in the comments. Lots of modern home remedies are actually based on good chemistry (Of course, this may mean they're too strong to be wise for every day use).
Clove oil is actually included in dental first aid kits.
Tea tree oil is a reasonable antiseptic, antibacterial, ect, and generally a useful toxin. Diluted, it's very useful on skin, and seems to deter minor infections. When possible, I add it to makeups or creams which I touch with my fingers, to deter bacteria growth.

The one on putting onions(makes me cry) on boils sounds cool. I’m gotta try it !

Honey definitely works WONDER for sore throat.

Pediculicide POISONS do not remove nits and are dangerous. Among the reactions to poison shampoo or lice “treatments” are seizures, mental retardation, many different allergies and respiratory problems, strange tingling, burning, itching, attention deficit disorders, brain tumors, leukemia, cancer and death.

I have used a sauna and/or salt water to safely and effectiely kill lice (but the nits remain).

I have also used ½ oz. of Safe Solutions, Inc. Lice R Gone® Enzyme Shampoo and/or their Enzyme Cleaner with Peppermint per shampoo-type application to safely remove both lice and nits.

As a soak for just about anything else. Cold salt water soaks for burns (assuming blisters, if any, haven’t burst!), and wounds. For sprains and strains. Warm for athlete’s foot or just about any other skin condition. Status: variable.

Grandma used to say (and it was marketed for it): Noxema for a sunburn.

Later, it was said that Noxema “held in” the heat and was actually NOT good for a sunburn.

But in looking this up again now, it seems that Noxema has joined the “beneficial” list again. So I Can’t actually say at this point if it works or not.
