The lovely lemon may cause a puckered face if eaten raw, but in a hot beverage, lemons will have you smiling. Hot lemonade has been used as a flu remedy since Roman times and is still highly regarded in the folk traditions of New England. Lemons, being highly acidic, help make mucous membranes distasteful to bacteria and viruses. Lemon oil, which gives the juice its fragrance, is like a wonder drug containing antibacterial, antiviral, antifungal, and anti-inflammatory constituents. The oil also acts as an expectorant. To make this flu-fighting fruit drink, place 1 chopped lemon -- skin, pulp, and all -- into 1 cup boiling water. While the lemon steeps for 5 minutes, inhale the steam. Strain, add honey (to taste), and enjoy. Drink hot lemonade three to four times a day throughout your illness.
