Even as medical science continues to search into the next century for a cure for the common cold, many of the herbs, spices, and concoctions grandma used at the dawn of this century can still make the symptoms more manageable today, says Mary Hardy, MD, director of integrative medicine at Cedars-Sinai Medical Center in Los Angeles.

Most colds and related viral infections -- characterized by gradual onset of sore throat, stuffy or runny nose, sneezing, coughing, and sometimes fever -- make us feel miserable before they go away within four to 10 days. Over-the-counter medications and more natural remedies can help, but Hardy urges patients and their caregivers to use caution and pay close attention to symptoms.

"Many people say 'cold and flu' when referring to nonspecific viral infections. When a doctor hears 'flu,' the doctor hears 'influenza,' which is a particular kind of infection that can be life-threatening," says Hardy. "The elderly and anyone with chronic health problems or a compromised immune system should be vaccinated against influenza. And if an illness comes on suddenly rather than gradually, includes high fever, enlarged lymph nodes, or severe body aches, they should consult their physician immediately."

For people in good general health, on the other hand, tried-and-true folk remedies can be quite effective in treating a routine, minor cold, according to Hardy. "In fact, aggressive treatment at the earliest onset of symptoms will sometimes limit severity or even abort a cold."
