In his writings, particularly in the Organon of Medicine, Samuel Hahnemann critically described various erroneous medical practices of his time. He referred to practitioners who administered remedies haphazardly, without a clear guiding principle, as belonging to the "**Mongrel sect**." According to Hahnemann, the method of medicine administration employed by this "Mongrel sect" was characterized by the Latin phrase "**Quid quid in buccam venit**," which translates to "**whatever comes into the mouth**." This phrase signifies the unprincipled and random use of various drugs without considering the specific needs of the patient or any systematic therapeutic approach.
