Hello,

so I started to watch something in Japanese and came across the following sentence:

根茎を蒸して乾燥させ煎じれば　解熱 鎮痛剤となる

Do I understand it correctly: if you steam and dry-boil(??) the root, you can be used (=it can become) for lowering of fever and as a painkiller.

what exactly is させ? -> 乾燥させ

Thanks!
