Linaria vulgaris
por E. A. Farrington — A Clinical Materia Medica
This drug produces fainting. It may be serviceable in fainting of cardiac origin. The " patient faints dead away without apparent cause." Linaria has repeatedly produced that symptom. It is true that there is some difficulty in confirming such a symptom as this, because, in most cases, the patient quickly returns to consciousness without recourse to any remedy. But if a patient who is subject to attacks of fainting of this kind is not only relieved but is cured by taking this drug, you know that this is the result of the remedy.
