Therapeutics is the branch of medicine concerned with treatment — not with naming a disease or explaining its causes, but with what you actually do about it: which drug, which dose, which procedure, and whether it works. A medical student studies anatomy to learn how the body is built, pathology to learn how it goes wrong, and therapeutics to learn how to put it right.

Therapeutics Therapeutics（治療學） is the branch of medicine concerned with treatment是醫學裡專門研究治療的分支——not with naming a disease or explaining its causes不是在命名疾病或解釋病因，but with what you actually do about it而是研究實際上該怎麼處理：which drug用哪種藥、which dose哪個劑量、which procedure哪種療程，and whether it works有沒有效。A medical student studies anatomy to learn how the body is built醫學生學解剖學是為了了解身體的構造，pathology to learn how it goes wrong學病理學是為了了解身體哪裡出問題，and therapeutics to learn how to put it right學therapeutics則是為了了解怎麼把它治好。

Two things to notice about the grammar. First, it ends in -s but behaves as one thing: 'therapeutics is a difficult subject', like 'physics is', 'mathematics is', 'economics is'.

Two things to notice about the grammar文法上有兩件事要注意。First首先，it ends in -s but behaves as one thing這個字雖然字尾有-s，但當作單數用：'therapeutics is a difficult subject'「治療學是門難科目」，like 'physics is', 'mathematics is', 'economics is'就像'physics is'、'mathematics is'、'economics is'一樣。

Second, the drug industry has stretched the word: companies now say 'therapeutics' as a plural countable noun meaning the treatments themselves ('new therapeutics for asthma'), and hundreds of biotech firms are simply named 'Something Therapeutics'. That business use is now everywhere, but a careful writer keeps the two apart.

Second第二，the drug industry has stretched the word藥廠產業把這個字用得更寬：companies now say 'therapeutics' as a plural countable noun meaning the treatments themselves公司現在會把'therapeutics'當可數複數名詞用，指療法本身（'new therapeutics for asthma'針對氣喘的新療法），and hundreds of biotech firms are simply named 'Something Therapeutics'而且有好幾百家生技公司直接取名叫「某某Therapeutics」。That business use is now everywhere這種商業用法現在到處都是，but a careful writer keeps the two apart但用心的作者會把兩種用法分清楚。

The related adjective 'therapeutic' is far more common in everyday speech and has drifted well beyond medicine — people call gardening or long walks therapeutic when they simply mean it makes them feel better.

The related adjective 'therapeutic'相關的形容詞'therapeutic' is far more common in everyday speech在日常口語裡常見得多，and has drifted well beyond medicine而且早就用到醫學以外——people call gardening or long walks therapeutic大家會說園藝或散步很therapeutic，when they simply mean it makes them feel better其實只是說這讓他們感覺比較好。
