The composition of Hydropsin must be considered essentially secret since the amounts of the several constituent drugs in a given amount of “dialysate” are not disclosed. The active principle of juniper is a volatile oil which is practically insoluble in water; it is difficult to believe that the “juice” of juniper submitted to dialysis could contain any material amount of the active constituent. No information is given as to the method used whereby the several dialysates are “physiologically standardized.” It therefore remains to be proved that the manufacturer of Hydropsin possesses any method whereby the dialysates of juniper (Juniperis communis), birch (Betula alba, the common European birch) and knot weed (Herniaria glabra) are so standardized. The claim is made that:
“Herniaria has long been recognized as one of the most valuable drugs in the treatment of dropsical affections due to cardiac impairment.”
On the contrary, Herniaria belongs to that large class of drugs which have been tried, found wanting and abandoned. It is a very old remedy, and the claims made for it are an inheritance from the early herbalists, with whom it was very popular. According to King’s American Dispensatory, it was “principally employed to cure hernia (hence its name) and to increase the flow of urine. It was also said to increase the flow of bile.... Internally and externally, it was praised in snake-bites, and the powdered plant was employed to kill maggots on unhealthy sores of horses. It was reputed to ‘crush’ and expel calculi from the kidneys and bladder....”
The Ernst Bischoff Company says that:
“Betula exerts both an antiseptic and stimulating influence on the urinary passages and is particularly serviceable where a catarrhal condition of the bladder exists. When combined with other diuretics, as in Hydropsin, the drug affords highly satisfactory results in the treatment of ascites, cardiac dropsy and hydrothorax.”
Birch is another drug which has been discarded. Few textbooks on materia medica even mention it. That it can materially affect the action of such powerful drugs as squill and digitalis is exceedingly doubtful.
An unwarranted implication—that in this preparation the powerful drugs digitalis and squill have been deprived of their dangerous qualities—is the assertion:
“Dialysis, removing all resins and colloidals, results in better tolerance on part of sensitive patients, and in more rapid absorption and elimination; which, in turn, means early therapeutic effects and little or no fear of toxic accumulation.”
That removal of colloids and resins materially affects the tolerance of these drugs is improbable. To claim that because of their removal, there need be “little or no fear of toxic accumulation” is utterly without warrant. The claim that one preparation containing digitalis is less likely to produce cumulative effect than any other digitalis preparation is contradicted by a mass of evidence.
It is claimed that Hydropsin affects “favorably all forms of dropsy or Edema that are at all amenable to medical treatment.” There can be no question but that squill and digitalis, or, better, either singly, used in suitable cases, may relieve dropsical effusions; but to claim that such a complex mixture as Hydropsin can favorably affect all forms of dropsy that are amenable to medical treatment is on its face unwarranted.
