1/2 teaspoon of manuka honey 10+ licked all around the inside of the mouth on retiring bed and sore throats, sniffles and coughs gone on waking up in the morning. Obtainable from New Zealand. Look up on internet. Works wonders

My own remedy for quick recovery or at least sleeping through recovery, haha... take hot showers to help moisten the respiratory track, drink plenty of ice-cold or hot drinks, depending on your weather, get sweaty, whether lying in the sun, or under thick blankets, again depending on the weather, and get lots of sleep, using sleep aids if you have something that works. Zzzzz.. Feel better in the morning!

Black Elderberry works well. It has antiviral, antibacterial properties and his high in Vitamin C so boosts the immune system.

Also Golden seal powder. A natural antibiotic internal and externally. tastes yukky, don't forget garlic and the C should be with zinc. IMHO

Ever since I dumped red meat, white flour, white sugar, and most processed food in my early 20s, I stopped getting colds. I raised my kids that way and they didn't even get the sniffles.

But eating a clove of raw garlic will cure up congestion-although it's best to eat it just before bedtime so one doesn't annoy people with the smell, and by the next day, the odor should be gone.

Also ginger and pepper tea boosts the immune system.
