Common Cold and Respiratory Infections

The cold is a viral infectious disease affecting the upper respiratory tract with symptoms including coughs, a runny nose, and sore throat. While these symptoms are usually mild and may resolve without treatment within a week to 10 days, some populations may experience severe complications and some cases can last as long as three weeks. With no cure and with adults having an average of two to three colds per year (children typically getting many more), it is no wonder millions of people seek to prevent or treat their colds with herbal medicines.
