  Someone believed to cure illness, often without formal medical training, sometimes using traditional or folk methods; informal, slightly old-fashioned or spiritual tone.

  指被认为能治病的人，往往没有受过正规医学训练，有时使用传统或民间方法；语气较随意，带有一点老式或神秘、灵性的色彩。

  那位老妇人被公认是一位治愈者，用草药治好感冒。

Therapist and healer both mean someone who helps the sick recover. Therapist is a licensed professional treating mental or physical problems. Healer cures illness without formal training, using traditional or folk methods, with an informal, spiritual tone. Healer's object sense is not compared here.

两者都指为病人治病、助人恢复健康的人，但 therapist 指受过专业训练、有资格证的治疗师（心理或身体治疗），语气正式、医学色彩浓；healer 更强调传统或非正规的治愈者，甚至带有神秘、民间色彩，语气较通俗。这里不比较 healer 作“能治病的事物”（thing）这一义项。
