A man aged 57, who had lived freely in the summer of 1784, became affected with œdematous swelling of his legs, for which he was advised to drink Fox Glove Tea. He took a four ounce bason of the infusion made strong with the green leaves, every morning for four successive days.
On the 5th he was suddenly seized with faintness and cold sweatings. I found him with a pale countenance, complaining of weakness, and of pain, with a sense of great heat in his stomach and bowels. The swelling of the legs was entirely gone, he having evacuated urine in very large quantities for the two preceding days. He was affected with frequent diarrhœa. The pulse was very quick and small, and his extremities cold.
A small quantity of broth was directed to be given him every half hour, and blisters were applied to the ancles, by which his symptoms became gradually alleviated, and he recovered perfectly in the space of three weeks; except a relapse of the anasarca, for which the Digitalis was afterwards successfully employed, in small doses, without any disagreeable consequence.
CASE VII.S—— D——, a middle aged single woman, was affected in the year eighty-one, with a painful rigidity and slight inflammation of the integuments on the left side, extending from the ear to the shoulder. In every other particular she was healthy. The use of warm fomentations, and opium, with two or three doses of mercurial physic, afforded her ease and the inflammation disappeared, but was succeeded by an œdematous swelling of the part, which very gradually extended along the arm, and downward to the breast, back, and belly. Friction, electricity and mercurial ointment were amongst the number of applications unsuccessfully employed to relieve her for the space of three months, during which time she continued in good general health.
In November she became ascitic, passing small quantities of urine, and soon afterwards a sudden dyspnœa gave occasion to suppose an effusion of water in the thorax. The Digitalis, squills, and cantharides were given in very considerable doses without effect. She died the latter end of December following.
CASE VIII.W—— C——, a collier aged 58, was attacked in the spring of 1783 with a tertian ague, which he attributed to cold, by sleeping in a coal pit, and from which he recovered in a few days, except a swelling of the lower extremities, which had appeared about that time, and gradually increased for two or three months. The legs and thighs were greatly enlarged and œdematous. His belly was swelled, but no fluctuation perceptible. He made small quantities of high coloured water. The appetite bad, and pulse feeble. He had taken many medicines without relief, and was now so reduced in strength, as to sit up with difficulty. An infusion of the Digitalis was directed for him, in the proportion of one ounce of the fresh leaves to a pint of water, two ounces to be taken three times a day, until the stomach or bowels became affected. Upon the exhibition of the sixth dose, nausea supervened, and continued to oppress him at intervals for two or three days, during which he passed large quantities of pale urine. The swelling, assisted by moderate bandage rapidly diminished, and without any repetition of his medicine, at the expiration of sixteen days, he returned to his labour perfectly recovered.

1785.
CASE.
Jan. 5th. Mrs. M——, Æt. 48. Hydrothorax and anasarcous legs, of eight months duration. She had taken jallap, squill, salt of tartar, and various other medicines. I found her in a very reduced state, and therefore directed only a grain and half of the Pulv. Digital. to be given night and morning. This in a few days encreased the secretion of urine, removed her difficulty of breathing, and reduced the swelling of her legs, without any disturbance to her system.
Three months afterwards, a severe attack of gout in her legs and arms, removing to her head, she died.
Dr. Stokes had an opportunity of examining the dead body, and I had the satisfaction to learn from him, that there did not appear to have been any return of the dropsy.
[10] In the three last recited cases, the medicine was directed in doses quite too strong, and repeated too frequently. If Esther K—— could have survived the extreme sickness, the diuretic effects would probably have taken place, and, from her time of life, I should have expected a recovery. Wm. T—— seems to have been a bad case, and I think would not have been cured under any management. G. R—— certainly possessed a good constitution, or he must have shared the fate of the other two.
OF THEPREPARATIONS and DOSES,
OF THE
FOXGLOVE.
Every part of the plant has more or less of the same bitter taste, varying, however, as to strength, and changing with the age of the plant and the season of the year.
ROOT.—This varies greatly with the age of the plant. When the stem has shot up for flowering, which it does the second year of its growth, the root becomes dry, nearly tasteless, and inert.
Some practitioners, who have used the root, and been so happy as to cure their patients without exciting sickness, have been pleased to communicate the circumstance to me as an improvement in the use of the plant. I have no doubt of the truth of their remarks, and I thank them. But the case of Dr. Cawley puts this matter beyond dispute. The fact is, they have fortunately happened to use the root in its approach to its inert state, and consequently have not over dosed their patients. I could, if necessary, bring other proof to shew that the root is just as capable as the leaves, of exciting nausea.
STEM.—The stem has more taste than the root has, in the season the stem shoots out, and less taste than the leaves. I do not know that it has been particularly selected for use.
LEAVES.—These vary greatly in their efficacy at different seasons of the year, and, perhaps, at different stages of their growth; but I am not certain that this variation keeps pace with the greater or lesser intensity of their bitter taste.
Some who have been habituated to the use of the recent leaves, tell me, that they answer their purpose at every season of the year; and I believe them, notwithstanding I myself have found very great variations in this respect. The solution of this difficulty is obvious. They have used the leaves in such large proportion, that the doses have been sufficient, or more than sufficient, even in their most inefficacious state. The Leaf-stalks seem, in their sensible properties, to partake of an intermediate state between the leaves and the stem.
FLOWERS.—The petals, the chives, and the pointal have nearly the taste of the leaves, and it has been suggested to me, by a very sensible and judicious friend, that it might be well to fix on the flower for internal use. I see no objection to the proposition; but I have not tried it.
SEEDS.—These I believe are equally untried.
From this view of the different parts of the plant, it is sufficiently obvious why I still continue to prefer the leaves.
These should be gathered after the flowering stem has shot up, and about the time that the blossoms are coming forth.
The leaf-stalk and mid-rib of the leaves should be rejected, and the remaining part should be dried, either in the sun-shine, or on a tin pan or pewter dish before a fire.
If well dried, they readily rub down to a beautiful green powder, which weighs something less than one-fifth of the original weight of the leaves. Care must be taken that the leaves be not scorched in drying, and they should not be dried more than what is requisite to allow of their being readily reduced to powder.
I give to adults, from one to three grains of this powder twice a day. In the reduced state in which physicians generally find dropsical patients, four grains a day are sufficient. I sometimes give the powder alone; sometimes unite it with aromatics, and sometimes form it into pills with a sufficient quantity of soap or gum ammoniac.
If a liquid medicine be preferred, I order a dram of these dried leaves to be infused for four hours in half a pint of boiling water, adding to the strained liquor an ounce of any spirituous water. One ounce of this infusion given twice a day, is a medium dose for an adult patient. If the patient be stronger than usual, or the symptoms very urgent, this dose may be given once in eight hours; and on the contrary in many instances half an ounce at a time will be quite sufficient. About thirty grains of the powder or eight ounces of the infusion, may generally be taken before the nausea commences.
The ingenuity of man has ever been fond of exerting itself to vary the forms and combinations of medicines. Hence we have spirituous, vinous, and acetous tinctures; extracts hard and soft, syrups with sugar or honey, &c. but the more we multiply the forms of any medicine, the longer we shall be in ascertaining its real dose. I have no lasting objection however to any of these formulæ except the extract, which, from the nature of its preparation must ever be uncertain in its effects; and a medicine whose fullest dose in substance does not exceed three grains, cannot be supposed to stand in need of condensation.
It appears from several of the cases, that when the Digitalis is disposed to purge, opium may be joined with it advantageously; and when the bowels are too tardy, jalap may be given at the same time, without interfering with its diuretic effects; but I have not found benefit from any other adjunct.
From this view of the doses in which the Digitalis really ought to be exhibited, and from the evidence of many of the cases, in which it appears to have been given in quantities six, eight, ten or even twelve times more than necessary, we must admit as an inference either that this medicine is perfectly safe when given as I advise, or that the medicines in daily use are highly dangerous.
