My husband having Cough from past few days and nose block in between he was feeling good after taking steam and Thaleesapatradi Choornam and Swasamritham syrup but when he stopped taking that it got again and now I see that while spitting the cough some blood stain is there and this is been four days now. He is a fitness trainer and every morning by 5 he has to leave from home. He use to have 9 egg whites and meals in between. He also has light cholesterol. Is there anything to worry about the blood stain? Any solution for that. His dad was also having very bad cough and cold from some days.
