The medicine at top, Bactocin, is an antibiotic. The two others soothe the gut.
This is what I thought a few weeks ago when I was convinced I had amoebic dysentery:
If the number of bathroom visits exceeds the number of hours in a day; if your stomach is distended so the shorts, which were too loose yesterday, cannot be buttoned; if it takes five minutes of sitting on the bed to work up the energy to look for your sandals and another five minutes to gather the stamina to slip into them; and if you feel ravenous but the thought of eating makes you nauseous -- then you probably have amoebic dysentery.
I was wrong.
