COPD and frequent cold, cough. Possible.

My mother aged 77 was diagnosed with asthma for the last 10 years. She is taking inhaler for that. However she is also suffering from seviour cold and cough which recurre every month. Earlier she was facing such a cold and cough once in every year that the frequency increased to 2-3 times a year. And from the  last october every month. Pulmonologist earlier used to give clavam 650 which is now not responding. Doctor prescribing cortisteriods and clarithomycin. However the frequency of cold and cough attack is increased from 30days to 15 days i. e.  after response of steroids and antibiotic and after recovery only after a gap of 5-7 days again cold and cough with serious nature occurring. Already tried with homeopathy and presently ayurvedic taking. Is such a recurring cold and cough treatment is not possible.
