• 治療法ちりょうほうCommon

• 治療ちりょうJLPT N1approx.Common

  治療ちりょうよりも予防よぼう。↗

  Prevention is better than cure.

For medical 'remedy' pick 治療法 for a method or cure, 治療 for treatment as care, and 療法 for a therapy as an approach; 矯正 is for remedying faults or defects, while 仕様 is rarely about remedies at all.
