From the classic texts

“This salt leads all other remedies in tenesmus of the rectum, which is incessant, and is not relieved by the stool. The tenesmus often involves the bladder as well.”

William Boericke, Pocket Manual of Homoeopathic Materia Medica (1901)

“Tenesmus: of bladder, with intense burning in urethra; urine hot, burning, scanty or suppressed; in drops with great pain…”

Henry C. Allen, Keynotes and Characteristics (1898)

Acute remedies can be a starting point for short-term complaints. Ongoing or recurring issues call for a full case: a detailed conversation about your physical, mental and emotional symptoms, so the remedy fits you as a whole person.
