After making these remarks upon the method of cure, I shall conclude with some observations on different remedies, which have been proposed as palliatives, where the operation is not admirable, or will not be consented to, and which have even been supposed capable of changing the mode of acting altogether, and producing of themselves a cure. These remedies I shall divide into general and topical. Of the general remedies, those which have been most frequently, and with the greatest confidence, employed, are narcotics, such as the cicuta, opium, nightshade, &c. The cicuta is a medicine which was, at one time, in very high repute, and owed its reputation to the experimenting talent of Storck, who has written several libelli on this plant. According to him, cicuta possesses very evident powers over cancer, and has cured a great many cases; but, in less prejudised hands, it has been much less successful; and even in many of the instances adduced by Baron Storck of its utility, it is by no means proved, that the disease was really cancer. The present opinion of the public seems to be very unfavourable with regard to this medicine; and from the numerous instances in which it has failed, this opinion seems to be very just. Alongst with the proper local applications which have been formerly noticed, it sometimes is of service in removing simple schirri[137]; but I have never found it of any service when the schirrus had affirmed the cancerous inflammation, much less when it has proceeded the length of ulceration. In the last case, I have never found it even produce the temporary melioration which many talk of. [137] If I am not mistaken, the present Dr. Monro mentions, in his lectures, one instance, in which a small schirrus appeared to be removed by it; but whether this was simple or cancerous, I do not know. The common way of exhibiting the hemlock, is to begin with small doses, and increase these gradually, until they produce vertigo: For this purpose, we may begin with two grains of the extract, or four of the powder, recently prepared, twice or thrice a-day, and gradually increase the quantity[138]. In this way, we find that some patients have come to take an ounce of the extract daily; but if a much less quantity than this produce no good effect, we may consider it as useless to continue a remedy, which, in this dose, must injure the constitution every day that it is continued. On the continent, the hemlock has been used in the form of a bath; but it is so disagreeable, that few can be brought to use it. [138] As different parcels of this medicine may not be of the same strength, it is prudent, when we begin a new supply, that we diminish the dose at first, if it have formerly been very considerable. By not attending to this, fatal effects have followed.
