Histaminum has not had a homoeopathic proving, but there has been experimental work with Histaminum 7c in which a blocking of the degranulation of Basophils was observed. The author has used Histaminum in a few cases of allergic rhinitis and asthma where indicated remedies were not succeeding and some of the cases showed remarkably good response. A 38 year old woman had started suffering from asthma 13 years previously, just after the birth of her first child. Her attacks were more frequent in the summer. Arsenicum album gave her no relief from one particular asthma attack and as she had persistent asthma trouble for the following 25 days she was prescribed Histaminum 7c. This was successful and since then Histaminum has enabled her to control the attacks and make them less frequent. Cases are also given of the successful treatment of pustular or oozing eczema with Aethiops antimonialis thus avoiding the use of an antibiotic.
