Those herbs have no effect on the immune system, other than as a
placebo. If you have pneumonia or bronchitis, you should see a doctor
and get actual medical treatment with proven medications.

i don't have any answers for you here but...

even though we are constantly warning folks to be leery of preparations that
claim to boost the immune system, i have heard of some folks who take some
of these supplements without ill effect and perhaps with some help.

So my feeling is that really, it's very much a YMMV thing and that if you
want to try it, then you should as long as you talk to your doctor about it
first.  They need to know what you're doing whether your response is good or
bad.

also, make sure and keep track of when you started it and perhaps keep a
general symptom diary for a few weeks.  Responses (either way) can be hard
to track sometimes without good records.  Also, i'd recommend that you have
a symptom diary at *least* one week before starting the regimen.  you need a
baseline.  otherwise i can be even harder to figure out if some reaction or
improvement you're having is due to the addition of the supplements or just
chance because you happened to get too much UV the day after you started the
med or something like that.

Let us know what you decide to do and if you do go on it, if you get any
relief.  We're all far too different medically to totally disregard
treatments that are not high risk.  I suspect this is a low risk regimen.

I'd be leery of taking any sort of unprescribed "natural" medication.
You never know what the active ingredients are, in what quantity you
receive them and how they might interact with anything you're already
taking.
