Spoonful of Medicine Could Be Wrong Dose
When Cornell University researchers asked 195 participants to pour one teaspoon of night-time flu medicine into kitchen spoons of different sizes, they poured an average of 8 per cent too little (using midsize spoons) or 12 per cent too much (using large spoons). Repeat dosing mistakes may make medicen ineffective or even dangerous. Always use a measuring cap, a dropper or dosing spoon.
"dropper" も少量の液体量を量る器具のようですが、どんな物でしょうか？ 辞書を見ます。

目盛りのついたスポイドの事ですね。スポイドは英語と思っていましたが、調べると元はオランダ語のようでした。
