I've had mild bronchitis.
It was a persistent cough after a flu; which did not get better, with periods of actual bronchitis where i was hacking up colored phelgmn.
The coughing and lots of phlegmn irritated things and made things worse, and possibly reinfected even after good periods.
Through all of this, you don't feel terrible, you can go about your life, and be walking wounded, it's just an irritation and you know you aren't 100%.
This was like over 2 years worth of time and people thought i was like i've done 20 years of smoking or always sick
So definitely half of it is killing what's in there, and the other half is getting your lungs and body back in sync and fully recovered so other stuff doesn't' just re-infect you.
I think definitely it's made my lungs and more susceptible to other injury and then before going through this 2 year ordeal.
So it suits you to take precaution and steps to really knock it out so you don't go down the same path
As far as home remedies:
-Get yourself a digital room thermometer with humidity meter ($10 at amazon or hardware store). Be sure that stays in the "OK", and around 50% relative humidity.
-Get yourself a humidifier if above is not achievable.
-If your room is dirty or your air is not very fresh, take efforts to change that. Vacuum, clean your room more often as well as washing your bedding more often with clean-rinse detergents. The dust and mold or even detergents don't help your recovery. Get fresh air in there. Air purifier if your outside air is not good and you don't have access to fresh air.
-if you have weird [censored] on your tongue or mouth get a tongue scrapper and mouthwash and use it morning and night before you go to bed. Same with your sinuses, if you have lots of stuff in your sinuses, you may need to consider using a sinus rinse.
-As a homeopathic remedy i tried all kinds of teas and tonics including the usual OTC cold/cough suppresents (these consist mostly of methol), and weird asian eastern medicine things like stewed peaches or pears or lemons and honey and other medicines (also consisting mostly of menthol). None of those made a difference...exceot
I will say what did help (for me) was "real" ginseng tea (korean granular)actually seemed to make a difference for me.
You may need to go to healthfood or asian market or online to get this, and be forewarned ginseng is relatively expensive.
Just mix a packet with warm/hot water and it makes a not-horrible tasting light tea. Drink every morning. It's over a $1 a packet, but rather then hacking up and coughing all the time it's worth it.
Maybe see if you can get better on your own. But when it's been like a month and you're still coughing, and you're feeling miserable every start of the morning, then you start reaching for your wallet and plunk down the money for magic ginseng tea.
