CASTA-FLORA
Report of the Council on Pharmacy and Chemistry
Casta-Flora is one of those complex preparations which are offered to the medical profession, with plausible arguments in support of the claims made. It is put out by the Wm. S. Merrell Chemical Co., Cincinnati. Each fluidounce is said to represent:
“Castanea, fresh leaves, 40 gr.; Passiflora, fresh plant, 40 gr.; Gelsemium, green tincture, 8 minims; Inula, represented by the camphoraceous stearoptene Helenin, 20 grs.; Iodized Lime, 8 grs.; Menthol, 1-4 grs.; Aromatic Syrup Yerba Santa, 60 minims.”
It is said to be:
“A new combination of well-tried remedies of especial value in pertussis and other spasmodic coughs. It is composed of astringent, antispasmodic, sedative and expectorant agents, that control the paroxysms, relieve the irritation, promote expectoration, and give tone to mucous membranes involved.”
Still more exaggerated claims are made for the individual constituents of Casta-Flora, partly by direct statement, partly by inference. For example:
“Castanea is almost a specific in whooping cough and other spasmodic coughs.
“Passiflora is a narcotic, sedative and antispasmodic without habit-forming properties, nor does it lock up the secretions and upset digestion like opiates.
“Inula (elecampane) has been employed as a cough remedy in England for centuries. Its action is similar to guaiacol and creosote. Its active principle, helenin, is destructive of tubercle bacilli in dilutions of 1 to 10,000.
“Iodized Lime, Menthol, and Yerba Santa are too well known as expectorants and antiseptics to require more than passing mention.”
That Casta-Flora is a “new” combination may be admitted; it is improbable that exactly this combination of obsolete drugs was ever before selected for any purpose whatever, but the statement is misleading in that no new principle of therapeutics is involved. On the contrary, the combination is just what might be expected from haphazard choosing of discarded and nearly forgotten drugs. It seems incredible that a reputable firm of manufacturing pharmacists would make the positive statement that castanea is almost a specific in whooping cough. Why not say it is a specific? It would be about as true. A specific or “almost specific” for this disease would rank among great medical discoveries; but castanea is merely a slightly astringent drug neither better nor worse than scores of other astringent drugs that have been tried, found valueless and discarded.
Hardly less surprising are the statements regarding passiflora. This herb has been on the market about three quarters of a century. Not only has it never established itself in scientific medicine, but it is not even mentioned in modern standard works on therapeutics.
Of all the statements made in the circular perhaps the most remarkable, in that it is so dangerously misleading, is that regarding helenin, the active principle of elecampane. The statement that this principle (helenin) is destructive of tubercle bacilli in dilutions of 1-10,000 can only mean that it is of extraordinary value in the treatment of tuberculosis; in fact, it is definitely stated that the action of elecampane is similar to that of guaiacol and creosote.
It is obvious that any drug which would destroy the tubercle bacilli in the human lungs without exerting a toxic action on the patient would be a great contribution to medicine. But although elecampane may have been used for centuries it has proved to have little, if any, merit, and even the National Standard Dispensatory, p. 848, says: “Elecampane was formerly employed as a tonic, stimulant, diuretic, diaphoretic, expectorant, and emmenagogue, but has now largely fallen into disuse.” One looks in vain in the standard textbooks on therapeutics for a description of the uses of inula (or elecampane), and of its so-called “active principle,” helenin.
The circular to which reference has been made says, referring to the use of castanea and passiflora in the treatment of whooping cough:
“Gelsemium, when made from the fresh, green plant—as is Merrell’s—is an excellent adjuvant to the above drugs, and allays the nervous irritability so frequently present.”
H. C. Wood, Jr. (Pharmacology and Therapeutics, 1916, p. 160), says of gelsemium: “Gelsemium was originally employed as an arterial sedative and febrifuge in the malarial fevers of the South, and subsequently in sthenic fevers. It appears in some way to depress the bodily temperature, but it does not appear probable that any advantage to be derived from it will counterbalance the danger attending its employment in the large doses required. In asthma, spasmodic laryngitis, whooping cough, and nervous cough it has been recommended by Bartholow, but is little used.”
That is about as favorable a statement for the drug as is to be found in the textbooks, and it serves to illustrate how little new there is in this mixture of obsolete drugs that Merrell seeks to market as one possessing extraordinary therapeutic value.
Even though the ingredients, or certain of them, were singly useful in the treatment of those conditions for which Casta-Flora is recommended, no one could possibly foresee the effect in any given case of such a jumble of drugs, both active and inert, as is said to be represented in this preparation. The prescribing of such mixtures, the action of which cannot in any way be foreseen, is plain charlatanism.
In addition, the various drugs in Casta-Flora are present in such proportions that the dose of each of the several ingredients bears no relation to the commonly accepted dose.
Casta-Flora is not acceptable for New and Nonofficial Remedies.—(From The Journal A. M. A., Jan. 27, 1917.)
