Dr. FRANK does not say much concerning the bark of pomegranate root, which has come into vogue lately as a remedy for taenia. He refers to the Med. Chirurg. Transact. Vol. XII. for accounts by some English physicians, and remarks, that Dr. GOMEZ, the Portuguese physician, had cured 14 cases with this bark. Dr. POLLOCK (vide Ed. Med. and Surg. Journal, Oct. 1819) treated a child, aged 14 months, with the decoction of bark of pomegranate root, so far back as the year 1811. This infant, under the use of the medicine, discharged at several times upwards of 30 feet of taenia solium, and was cured. We learn also from the Med. Repository,[22] that MM. DESLANDES, SOURYA, and BOURGEOISE, have employed pomegranate with great success; that the decoction generally expelled the worm in two hours; that it sometimes occasioned vomiting and griping pains; and that it has been a common remedy for tape worm, in the East Indies, and among the blacks of St. Domingo. From the same source we are informed, that the French pharmaceutists recommend, before boiling the bark, that it should be allowed to swell (macerate) in cold water. [Symbol: ounce]ij of bark should be boiled in lbij of water to [Symbol: ounce]xii. Of this decoction, [Symbol: ounce]ij may be taken every half hour. The worm is here said to be passed often in twelve hours instead of two. It may be necessary to continue this plan four or five days, taking care to suspend the medicine, in case any vertigo, or intestinal disease supervenes. A dose of castor oil is recommended after the 4th bottle; even though the worm be happily for the patient expelled. In the Revue Medicale is a case, in which pomegranate succeeded in discharging three ells of taenia; but the patient broke off the worm in attempting to extract it with too much violence. This circumstance recalls us to the consideration of Dr. FRANK'S communication. He recommends much caution in the extraction of those portions of taenia, which have remained partly in the intestine; and says that Dr. CAGNOLA proposed touching the extruded portion with prussic acid, in hopes of killing the whole animal by means of this violent poison. Dr. GARLEKE adopted this plan on an extruded portion of four inches in length, and in one hour afterwards the _whole animal came away dead_. Dr. F. suggests, that the electric shock might weaken the taenia, so as to cause it to let go its hold, and thus be unresistingly extracted. BRERA recommended that the worm should be tied with a piece of silk. In this manner, it is retracted into the bowel, but begins to descend again not long afterwards. He dissuades from any attempt at forcible extraction, which excites the most distressing sensations in the bowels, and causes the risk of bringing on convulsions.
