The easy-to-make mixture requires just seven ingredients, Barbara O'Neil promises that drinking it daily can shorten illnesses from the flu, a cold, a sinus infection or just about any respiratory illness. โThis is your natural antibiotic, this drink,โ she said. โWhen someone has bronchitis or a sinus [infection] or pneumonia, they take the flu bomb.โ The first ingredient is garlic, and she advises using as much as you can bear drinking, calling it a โnatural antibiotic.โ Garlic contains the antibiotic allicin, which gets released when a clove is chewed or crushed up. Itโs been used to fight disease for thousands of years, though research on its effectiveness at preventing and fighting colds is limited. One study found that people who took a garlic supplement for 12 weeks during cold season got fewer colds than those who didnโt โ and their colds cleared up faster than those not taking garlic. OโNeillโs flu bomb also contains eucalyptus oil, which she said is โnice for clearing airways.โ Eucalyptus is in fact present in a lot of cold and flu remedies because it can relieve congestion and loosen phlegm. Other ingredients include ginger and honey, both natural expectorants, and as much cayenne pepper as one can handle, as the capsaicin in pepper has been found to relieve congestion and sneezing. OโNeill says to drink it three times a day when symptoms set in, โand often, after two or three days, thatโs enough.โ Ingredients: *1 clove garlic, crushed *1/4 teaspoon ginger, grated *1 drop eucalyptus oil or tea tree oil *cayenne pepper *juice of a lemon *1 teaspoon honey *1/2 cup hot water
