My father aged 82, is suffering from phlegm with wet cough for the past 6 months. He is a sugar patient. When his throat is getting dry he is getting itching at throat and phlegm and cough is coming. Digestion is good. Gradually he is loosing his weight (now 45 kgs). He is taking very little food. No expectorant and cough tablets are worked. We met 5 doctors, but nobody has given right medicine. Now I want some homeopath doctors advice. Thanks.
