Indurative is a technical term used in medical sciences. It refers to the hardening of a tissue or an organ, usually as a result of chronic inflammation or scarring. Some synonyms for indurative that can be used interchangeably in medical contexts include sclerotic, fibrous, or cicatricial. Additionally, the term indurative can sometimes be substituted with induration as it refers to the same medical condition. Indurative lesions or masses can be observed in several disorders such as tuberculosis, syphilis, or Crohn's disease. It is important to use accurate and appropriate synonyms to avoid ambiguity or confusion while diagnosing or treating patients with indurative conditions.
