Osam Dazaiの小説 "The Setting Sun" (Donald Keen訳)を読んでいます。
The old doctor, who normally gave forth nothing but jokes, rushed this time into the sickroom in a kind of rage and at once began his examination. This concluded, he muttered to no one in particular, "She's grown weaker." He gave Mother a camphor injection.
"camphor injection" の "camphor" は楠木から作られる樟脳ですが、樟脳から何かの注射液ができるのでしょうか？
・Collins Dictionary: a whitish, translucent, crystalline, pleasant-odored terpene ketone, C10H16O, obtained from the camphor tree, used chiefly in the manufacture of celluloid and in medicine as a counter-irritant for infections and in the treatment of pain and itching
・Cambridge English Dictionary: a white substance with a strong smell which is used in medicine and to keep moths (= flying insects) away from clothes that are stored
樟脳から何等かの薬品も作られるのでしょうね。もしかして、カンフル剤と言う言葉を聞いたことがありますが、このカンフルってcamphorから来たのでしょうか？ カンフルを調べると、心臓の働きを活発にして、血圧を上昇させる目的で注射されていたものが、いわゆる「カンフル剤」とありました。（https://ishikawa-mental.com/mt/archives/000106.html）
