Effect of Homoeopathic remedy Merc Cor

Dr Puneet Kumar Misra

Abstract- mere cor is the inattention medicine in the common clinical practice in the gastric disorder, but this medicine having a remarkable and quick effect on the acute as well chronic disorder of the rectal region associated with large intestine along with gastric and small intestine due to dietary habit or illness .

Introduction – the Diarrhea and Constipation is the disordered defecation. but many   patient  have  normal tendency of defecation, but  before ,during and  after  defecation the mild to moderate pain, burning and uneasiness  in the rectal region  with or without lower abdomen pain with feel of  incomplete defecation  and  which  associated with dietary change  in many person .

Key words – Diarrhea, Constipation,   Defecation,

Abbreviation- IBS- Irritable bowel syndrome . GI-gastrointestinal , UC- ULCERATIVE COLITIS,

DEFECATION – Tonic contraction of the puborectalis muscle, which forms a sling around the recto anal junction, is important to maintain continence; during defecation, sacral parasympathetic nerves relax this muscle, facilitating the straightening of the recto anal angle. Distention of the rectum results in transient relaxation of the internal anal sphincter via intrinsic and reflex sympathetic innervations. As sigmoid and rectal contractions, as well as straining (Valsalva maneuver), which increases intra abdominal pressure, increase the pressure within the rectum, the recto sigmoid angle opens by >15°. Voluntary relaxation of the external anal sphincter (striated muscle innervated by the pudendal nerve) in response to the sensation produced by distention permits the evacuation of feces. Defecation can also be delayed voluntarily by contraction of the external anal sphincter. 1

Diarrhea is loosely defined as passage of abnormally liquid or unformed stools at an increased frequency. For adults on a typical Western diet, stool weight >200 g/d can generally be considered diarrheal. A careful history and physical examination 
generally allow these conditions to be discriminated from true diarrhea. 1,2,3

Constipation is a common complaint in clinical practice and usually refers to persistent, difficult, infrequent, or seemingly incomplete defecation.  A person whose parents attached great importance to daily defecation will become greatly concerned when he or she misses a daily bowel movement; some children withhold stool to gain attention or because of fear of pain from anal irritation; and some adults habitually ignore or delay the call to have a bowel movement.1,2,3

Signs and Symptoms The major symptoms of UC are diarrhea, rectal bleeding, tenesmus, passage of mucus, and crampy abdominal pain.  Other symptoms in moderate to severe disease include anorexia, nausea, vomiting, fever, and weight loss. Physical signs of proctitis include a tender anal canal and blood on rectal examination. With more extensive disease, patients have tenderness to palpation directly over the colon. 1,2

Although CD usually presents as acute or chronic bowel inflammation, the inflammatory process evolves toward one of two patterns of disease: a fibrostenotic obstructing pattern or a penetrating fistulous pattern, each with different treatments and prognoses. The site of disease influences the clinical manifestations.

Because the most common site of inflammation is the terminal ileum, the usual presentation of ileocolitis is a chronic history of recurrent episodes of right lower quadrant pain and diarrhea.  

Extensive inflammatory disease is associated with a loss of digestive and absorptive surface, resulting in malabsorption and steatorrhea. 

Patients with colitis present with low grade fevers, malaise, diarrhea, crampy abdominal pain, and sometimes hemato chezia. Gross bleeding is not as common as in UC and appears in about one-half of patients with exclusively colonic disease.  . Perianal disease affects about one-third of patients with Crohn’s colitis and is manifested by incontinence, large hemorrhoidal tags, anal strictures, anorectal fistulae, and perirectal abscesses. Not all patients with perianal fistula will have endoscopic evidence of colonic inflammation 12

Irritable bowel syndrome (IBS) is a functional bowel disorder characterized by abdominal pain or discomfort and altered bowel habits in the absence of detectable structural abnormalities.   Furthermore, IBS symptoms are prevalent in non cardiac chest pain patients, suggesting overlap with other functional gut disorders.1,2

Lectures on homeopathic materia medica
In <dysentery> there is more violence; copious bleeding; great  anxiety, can scarcely leave the stool a second, great tenesmus of  rectum  and bladder; urging to urination and stool  is  constant;  great burning in the rectum. It is a violent case of dysentery. I  would  prefer  <Merc.>  in ordinary <Merc.> cases,  but  if  this  patient  is  not  relieved he will not live, and  Merc.  cor.  is  needed here.10

Leaders in homoeopathic therapeutics
Most persistent and  terrible tenesmus before,during and   after   stool; stool scanty, mucus tinged with blood. Of MERCURIUS CORROSIVUS we have to say that it   leads  all  other  remedies for TENESMUS  OF  THE  RECTUM.   This tenesmus  is incessant. Stool  does not relieve it,11

A manual of  pharmacodynamics
But when the large intestine are affected , whether with simple inflammation , with chronic ulceration, or with dysentery ,its effects are amongst the most brilliant thing in medicine .hahnemann was the first to recommend in the dysentery ,say (1822) that he had  found it almost specific  in the common autumnal invasion of the complaint .he gave the 15th dilution in the single dose ; but dr ringer reports correspondingly good result with hourly repeated dose of a hundredth of a grain .12
