Once the unit question is settled, the next problem is measurement, and this is where
a liquid asks something of you that a tablet does not.
Use the pipette, not a drop count
The panel puts two droppers at about 2 mL, which puts one dropper at about 1 mL.
Most glass pipettes carry a graduation on the stem, and that mark is your measurement:
draw up to it, check it at eye level, and take what is in the pipette.
Counting drops is not a measurement and cannot be made into one. Drop size changes
with the viscosity of the liquid, the temperature of the room, the angle you hold the
pipette at and how hard you squeeze the bulb. Two people counting the same number of
drops from the same bottle will not take the same amount, and neither will know it.
If your pipette has no graduation
A full pipette on a bottle this size is a dropperful; that is the unit the label
uses. Fill it to where the bulb stops drawing and take the whole pipette for one dropper,
or repeat for two. Cruder than a marked stem, and far closer to the label’s intent.
Two small habits. Do not touch the pipette to your tongue or teeth: it goes back into
the bottle for another month. And put the cap back on straight away.
