Granny style remedy that I haven't seen mentioned here: cut thin slices of onion, coat top of slice with honey, possibly put another layer of onion slices and another layer of honey or more. Put all of this in a closed container, in room-or-slightly colder temperature (but not fridge) for a few hours. Fumes from the onion melt the honey making it much more liquidy. Honey sips into onion and makes it less sharp. Eat onion and/or drink honey/onion liquid (or take with a spoon - it is quite intense). Put in fridge if you don't use all at once. Also nice as a condiment for some foods. Possibly placebo, but tends to help with cold and headaches.
