It was a favourite remedy of the Middle Ages, being used extensively in dilution in the treatment of scrofulous, phagedenic, cancerous and venereal ulcers, as a gargle and mouth-wash for aphthae, ulceration of the gums and diphtheria. Homeopathically it is indicated in cases characterized by great debility. Reports suggest it useful in aphthous ulcer, bleeding gums, offensive breath, gastralgia with contractive pain, flatulence, loss of appetite, hearty burn, sour eructations and vomiting, purpura haemorrhagia, etc. Literature suggests its successful use in craving for liquor.
