For Colds:
1/4 cup olive oil
10 or 11 garlic cloves, peeled

Put a lid on your mason jar or container and it will last in your fridge for about a month.

When you are fighting a cold or infection, slather some on your feet and then cover with two pairs of socks. Use old socks, because you never really get out the garlic smell. If you can bear it, when you have a cough/sore throat, put some on your chest. If you have a sinus infection, put it in your nostrils. Ear infection, in your ear.
