There is hardly any increase in the intestinal secretion, the drug being emphatically not a hydragogue cathartic. There is no doubt that its habitual use may be a factor in the formation of haemorrhoids; as in the case of all drugs that act powerfully on the lower part of the intestine, without simultaneously lowering the venous pressure by causing increase of secretion from the bowel.
The drug is obviously contraindicated in pregnancy and when haemorrhoids are already present.
For bleeding haemorrhoids tannic acid suppositories are useful, or tannic acid can be dusted on directly.
Opium rather than morphine is also usually employed to relieve the pain of haemorrhoids or fissure of the rectum.
Sulphur and sulphur waters such as those of Harrogate, Aix-la-Chapelle and Aix-les-Bains, have a powerful effect in congested conditions of the liver and intestines, haemorrhoids, gout and gravel.
