This is not a recipe for your average orange juice. In fact, it contains more citrus than your average cup of OJ to combat even the harshest cold. Equipped with immune boosters such as vitamin C and phytochemical, your pesky cough won't stand a chance.

What you'll need:

2 oranges
1/4-1/2 grapefruit (depends on how much grapefruit you can handle)
1/4 lemon
1/4 lime

Directions: 

1. Cut produce for efficient juicing
2. Juice produce
3. Cool in the fridge
4. Enjoy!
Note: Due to the potency of nutrients and sugar, you may want to dilute your juice with water.*
