Ph is for pharmacy

(the art or practice of preparing
and dispensing drugs and medicines;
a dispensary; chemist's shop)

Clinically tested
says the blurb.
Your cold or flu
symptoms will vanish
in half the time.
Our study group
got well after three
days; the placebo users
took six days. Proof!

By day three I'm
a downpour not
waiting to happen.
I'm a torrent, a rapids
I'm a spasm of sneezes.
I burn. I chill. A-choo!!!
The eyes run like rivers
the nose gets raw.
I'll let you know
how many days I
would have been suffering.
When I stop running.
