It is especially useful in haemorrhoids and constipation, and in functional disorders arising therefrom, especially functional disturbances of the heart, dysmenorrhcea, pruritus of the vulva, prolapsus uteri, etc. The haemorrhoids may be either blind or bleeding, though probably the latter predominate. The constipation is usually very obstinate, with painful protruding haemorrhoids. Has also proved useful in membranous dysmenorrhea, and pruritus during pregnancy, with the symptoms above given. Varicocele with rectal symptoms. May be useful in organic disease of the heart, and in ascites resulting therefrom. Has also been used in ascites from hepatic disease, with constipation and haemorrhoids.
