In this episode, we conclude the Mishnah Berurah’s discussion of the halachos of healing and medical treatment on Shabbos. The focus is on the prohibitions of tzove’a (dyeing), chovel (causing a wound), and related issues such as dressing wounds, extracting blood, and administering enemas. We explore when these actions are biblically or rabbinically prohibited, distinctions between intentional and inevitable outcomes, and when leniencies apply for the sick or in cases of indirect action. Also discussed: the difference between dyeing with blood versus dyeing with colorants, washing wounds, and the halachic principles governing modern parallels such as blood tests and medical procedures performed by non-Jews on Shabbos.
