Arm Intervention/treatment
Experimental: Tea1 group
This is the treatment group. This group will be taking 2 grams of the "three-seeds" mixture twice a day for three weeks.
Dietary Supplement: Three-seeds mixture
mixture of white mustard seeds, radish seeds and beefsteak plant (Korean perilla, a species of Perilla in the mint family, widely cultivated and edible for humans; a daily food for Korean people; many Japanese people drink as tea) seeds

Placebo Comparator: Tea2 group
This is the control group. This group will be taking 0.02 grams of the "three-seeds" mixture once a day for three weeks.
Dietary Supplement: Control
warm water with negligible amount of the three-seeds mixture

Primary Outcome Measures :
  1. Sputum and cough score [ Time Frame: One month ]
    Sputum and cough measured by Cough and Sputum Assessment Questionnaire. The minimum score of this questionnaire is 0, and the maximum score is 100, with lower scores indicating higher symptom/impact levels. The total score will be reported. The score will be summed to a total score.
