1. Ginger Tea. Ginger tea is easy to make. Measure 1/4 teaspoon of ground ginger into a heat proof mug or glass and pour 1 cup of boiling water over it. Cover with a saucer and let sit until cool enough to drink before straining. (I line a fine mesh strainer with a coffee filter to do so.) Sweeten with honey or sugar as desired.
Vicks VapoRub is considered absolutely unsafe for children under 2. Consumption of small amounts of one of the ingredients (camphor) can be fatal for children, and getting Vicks in your eye (hard to avoid in little ones) can cause eye damage. So, I would highly recommend against using it in young children.
Probably best just to rub it on your chest. Or put some in a bowl with boiling water, sit over it with a towel over your head and breath in the vapour. Vick's vapor rub, before, is okay to swallow, but now, because of strong ingredients, it's not okay. don't worry, it's not fatal, hehe.
