“Another little-known favorite of mine takes some forethought in the early summer. We've all seen ox-eye daisy (Chrysanthemum leucanthemum) in fields and on roadsides; maybe you even grow it in your garden. As long as you can properly identify it, and as long as you can pick some from a safe, pesticide-free area (without secreting it from your neighbor's garden, even if she does grow a ton), snag handfuls of blooms and dry them well before storing them in a clean, dry jar with a tight-fitting lid. When a stuffy nose comes along, make a mug of tea with a heaping teaspoon of dried blooms. In about 30 minutes or less, a stuffed nose will be clear, and it should stay that way effectively for 4 to 6 hours, same as any cold capsule -- without the side effects. This works best with swollen nasal passages or a drippy nose. Drink a cup of the tea up to 4 times a day.”
