I am writting regarding. Dr. Hale's posting on pseudophedrine.

As I mentioned before, I used The Nursing Mother's Companion as my resource
for this one.  She does say that pseudophedrine is a decongestant.  She says
that not much is known about their passage into milk, but that they can
decrease "milk flow."  It is unclear (to me) what her refrence source for
this is.

I hope this helps!
