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.
Vicks VapoRub is a topical ointment that contains petrolatum -- petroleum jelly -- which can cause respiratory tract irritation when inhaled. VapoRub is flammable under certain conditions and potentially toxic when ingested. It is a common cold and decongestant remedy that is safe when used appropriately but should not be added to a humidifier. Procter & Gamble, which manufactures Vicks products, also produces a line of Vicks-branded humidifiers. But the company cautions against using the ointment in warm-mist humidifiers and, instead, makes Vicks VapoSteam, a product that contains no petrolatum, to be used in a vaporizer.
