treatment for productive cough...

I've been sick for a week... and coughing for almost a week...
Took cough syrup, 枇杷膏, ginger tea... etc... all didn't really help to reduce my cough...

Hence, was googling for a remedy on cough... and this is what it recommends:

• Inhale steam from a tub of boiling water or hot shower to loosen phlegm in the throat and sinus congestion
• Drink at least eight glasses of water daily to loosen phlegm and thin mucus – it is also good for your overall health!
• Avoid eating foods such as dairy products, meat or fried foods that increase mucus production
• Drink hot liquids such as tea or chicken broth to moisten the airways and help the breaking up process
• Use a humidifier or cool mist vaporizer in your bedroom at night to thin the mucus – this helps to moisten the air and is particularly helpful during winter
• Limit exposure to irritants such as household cleaners, paint fumes, chemicals or cigarette smoke
• Add a few drops of eucalyptus oil to a vaporizer to loosen mucus and phlegm and relieve congestion
• Stop smoking as it will worsen respiratory conditions
• Eat spicy foods, horseradish or hot chili peppers to loosen mucus (So I must 以毒攻毒???)
