In simple chronic enlargement of glandular organs, the liver, the spleen, the mammary gland, or the testes, iodine is often of more service than any other medicine. The cause may be syphilis, struma, or malaria, and yet the same remedy be applicable.
I generally recommend 1 to 5 min. of tincture thrice daily for a long period, though sometimes iodides are better borne. External painting, or iodine compresses, should be used at the same time. Iodoform ointment, or iodoform collodion, is also to be highly recommended (v. pp. 70, 73).
