A communication from abroad by THE CHEMISCHE FABRICK VON HAYDEN, GESELLSCHEFT
MIT BESCHRAENKTER HAFTUNG, of Radebeul, near Dresden, Saxony, German
Empire, Manufacturers.
I, JOHN CLAYTON MEWBURN of the Firm of J. C. Mewburn and Ellis of 55 and
56 Chancery Lane in the County of London, Chartered Patent Agents, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:
This invention refers to the employment of silver for medical or curative
purposes.
It is well known, that salts of silver and also ordinary metallic silver, which is not
soluble in water, have been employed for medical purposes. It is however a perfectly
new discovery, that a special modification or form of silver, almost hitherto unknown, is
especially suitable for producing a new medicinal compound. Now the present
invention consists of a new ointment, unguent or salve prepared by means of soluble
silver, which has not hitherto been made use of for such purposes.
As a suitable compound I take for instance :-
15 per cent. of silver and
85 per cent. of some suitable substance for an ointment, unguent or salve, such
as Lanolin Hog's grease, wax or the like.
Any grease, fat or oil suitable for the purpose may be used as the main ingredient or
carrier in the ointment, unguent or salve, and to these substances any usual
perfuming and preserving ingredients, such for example as benzoic ether, may be
added. The essential element in this new ointment, unguent or salve is
however not the main ingredient or carrier, but the soluble silver; ointments, salves
or unguents as hitherto made have generally contained such a main ingredient or
carrier, but in none has soluble silver been an ingredient. The percentage of silver
may be varied at will, but a percentage of less than one per cent. and of more than
thirty per cent. is not suitable for the purpose. The ointment, unguent or salve
may be made liquid or more or less solid according to the main ingredient or
carrier employed.
The ointment, unguent or salve is specially adopted for use as an embrocation in
case of maladies which are based on septic causes, such for example as:-
Lymphangitis, Phlegmon, Septicemia, Puerperal fever and other septic maladies.
Two or three grammes of the 15 per cent. ointment, unguent or salve is a
The
suitable quantity. In applying it, it should be well rubbed into the skin.
application if necessary can be made repeatedly. If the ointment employed does not
contain 15 per cent. of the silver, but more or less, the amount employed must be
varied accordingly.
Having now particularly described and ascertained the nature of the said invention
as communicated to me and in what manner the same is to be performed, I
dealers that what I claim is. —
