Asthma and frequent throat and chest congestion

Thanks a lot doctor for your suggestions.
I will get back to you after he take two doses of Thuja 200c.

Hello doctor, My father has taken two doses of Thuja yesterday,, and he is mentioning that he is feeling a little more energetic today as compared to past few days. No noticeable difference in breathing as of now. Please suggest which medicine should he take now?

thanks a lot doctor for your advice. I'll keep you posted with the updates.

hello doctor,, my father is taking the medicine for past few days,, but these days his breathing problem has increased a lot.. It has become really difficult for him to climb up the stairs,, he took Ipecac twice after climbing up the stairs but not relief.. please suggest if he needs to take some other medicine as well in combination. Thanks in advance.

thanks a lot doctors, I appreaciate you guidence and suggestions.. he has started taking Nat Sulph as suggested by you. Ipecac he took only twice when he face extreme breathing problem.
And for Ars Alb 30, also please let me know how and what doses should I give to him.

thanks for you suggestions doctor.. Here I want to add few more details abt the problem that my father is facing.

1. He is diagnosed to have COPD: Chronic obstructive pulmonary disease.
2. He used to smoke a lot.. up to 25 cigarettes a day.
3. Always have caugh.
4. since last 2 years.. he has become very weak. He doesn't look weak from outside but has no energy.
5. He feels so low on energy all the time that even a normal walk of 15-20 meters leaves him running out of breath.
6. He doesn't get any asthama attacks as such,, but after any kind of work which involves some energy.. like walking, lifting any objects, climbing up stairs and even bathing makes him out of breath.
7. For past some time he was having continuous pain in legs and body.. and doctor prescribed calcium tablets for that after completing that course he is feeling a lil better.
8. He eats pretty ok.. niether much nor less but still don't have energy.

After talking to him today morning I realize that being weak (no stamina) is his main problem which is causing him these breath problem as well..

Please consider these points also in your analysis and suggest if there is anything which can be done to overcome so much of weakness.
I sincerely thank you for the advice.

Hello doctor, sorry I was not able to answer your question yesterday,, I have spoken to my father today and he told me that he has not taken Ars. Alb as of now, But he was telling that he took Ars Alb 30 for about 5 months.. almost regularly but is not taking it for past 6 months now. He told that he had very marginal relief during that time but not much.
And regarding the stomach,, he has a tendency to get stomach upset every now and then, after every week or 2 he catches cold and cough and his stomach also gets upset, which leaves him weak.

As I have mentioned in my first post that 2 yrs back he was hospitalized and was on oxygen for about 12-15 days. Since then he has not gained his health back.

And he was telling me that when he took Thuja as suggested by you last week, he felt some relief overall for about 2 days, But when he took Ipecac after climbing up stairs he didn't feel any relief.

I am really worried about him.
Please let me know if you need any further details.
Thanks in advance.

Yes doctor,, he is taking the natrum sulph 6X as you suggested earlier.
