A new study challenges long-held assumptions about the origins of a widely used medical treatment, suggesting its effectiveness may have been overstated in historical records. Researchers examined archival data and patient outcomes to question whether the therapy’s benefits were as significant as previously claimed. The findings could prompt a reevaluation of its role in modern medicine, particularly in cases where alternatives have since emerged. Critics argue the study’s methodology may still leave gaps, but it adds to growing debates over how historical medical practices are interpreted today.
