400. Cinchona Febrifuge, or Darjeeling Cinchona Alkaloid.This was really employed as a cheap substitute for Quinine. In 1875 Mr. Wood, the Government Quinologist, prepared from the bark of Cinchona succirubra and other species under cultivation at Darjeeling an alkaloid, or rather a mixture of alkaloids, which has received the provisional names of "Darjeeling Cinchona Alkaloid," and "Cinchona Febrifuge." A rough analysis shows that it contains: Quinine, 15·5; Cinchonidine, 29·0; Cinchonine, 33·5; Amorphous Alkaloid, 17·0; and Colouring Matter, 5·0 in 100 parts. It occurs in the form of a buff-coloured powder, of a peculiar disagreeable smell, and bitter, nauseous taste; insoluble in water, soluble in mineral and vegetable acids. 401. In the treatment of Intermittent Fever this remedy ranks next to Quinine, over which it possesses the advantage of being comparatively cheap, and, from its being manufactured in India, is within the reach of all. It has its disadvantages, however, being apt to create nausea, vomiting, with a burning sensation at the pit of the stomach, extending, in some 402. In Debility after Fevers it promises to be of great value as a tonic, given in small doses. It is worthy of a trial in Enlargement of the Spleen in combination with Sulphate of Iron (176). In Neuralgia, Faceache, Tic Douloureux, when assuming a periodical form, this remedy is well worthy of a fair trial. It should be given in full doses (10 grains) thrice daily for adults. 403. Closely allied to the foregoing is another form of collective Cinchona Alkaloids, to which its discoverer, Dr. de Vrij, has given the name of Quinetum. 404. Sugar.Shakar (Hind., Duk.), BhÚra, ChinÍ (Beng.), Misri (Punj.), SakkarÁ, Sharukkarai (Tam.), Shakkara (Tel.), Sharkkara, PanjasÁra (Mal.), SÍnÍ, Sakkere (Cing.), Saghia or Tagiya (Burm.), GÚla (Mal.). 405. This article is not usually regarded as a medicine, but Dr. Aitchison in his valuable notes, points out how he has utilised it as such with excellent effect; and as it is procurable throughout the length and breadth of India, it seems well worthy of notice in this place. Only the best and purest kinds should be employed for medicinal purposes. 406. In all forms of Ophthalmia (Country Sore Eyes, &c.), Dr. A. states that he has found a solution of one drachm of Sugar in three drachms of Water dropped into the eye every hour or so, never fail to afford relief, and that generally, if applied early, cuts short the disease at once. This practice, he adds, he has followed for twelve years, and used nothing else. Children, according to his experience, will actually come and ask to have the remedy dropped into their eyes, so great is the relief it affords. At bedtime, in these cases, it is advisable to apply to the eyelashes a little sweet oil or grease, and the first thing in the morning carefully to wash the eyes with hot milk and water. This solution is also useful for removing small foreign substances from the eye. 407. In Gonorrhoea and Vaginal Discharges the above solution is an excellent application, though not so uniformly useful as in Ophthalmia. In Gonorrhoea, it may be commenced with at once, the injections being repeated frequently during the day, in addition to general remedies; but in Vaginal discharges other remedies may be tried first. (See Index.) 408. Sugar is an excellent dressing for certain 409. Petroleum. Rock Oil.MittÍ-kÁ-tÉl (Hind., Duk.), MÁtiyÁ-tail (Beng.), Man-yenney, Man-tayilam (Tam., Mal.), Manti-tayilam, Manti-nÚnÉ (Tel.), MannunyannÉ (Can.), MattÍ-cha-tÉla (Mah.), MattÍ-nu-tel (Guz.), YÉ-nÁ (Burm.). 409a. Petroleum, a mineral oil, semi-liquid, somewhat of the consistence of treacle, tenacious, semi-transparent, of a deep sherry red or nearly opaque, tar-like brown, with a peculiar though not unpleasant aromatic odour and pungent acrid taste, exudes spontaneously from the rocks in volcanic regions, and collects on the surface of certain lakes in Persia, Burmah, Assam, and the islands on the Arracan Coast, as well as in Barbadoes, Trinidad, and other West Indian Islands. As a medicinal agent, it is a terebinthinate (turpentine-like) stimulant, and as such appears to act specially on the kidneys, increasing in a marked degree the urinary secretion. The dose is about half a fluid drachm (thirty drops) suspended in mucilage. 410. Petroleum is very generally employed by the Native practitioners externally as a stimulant in 411. In Skin Diseases, it is a useful external application, and a case of Chronic Eczema, which had resisted a host of remedies cured by it, is recorded by Dr. J. W. Mudge (Indian Ann. of Med. Science, 1854, p. 450). He used it incorporated with Soap in the proportion of a drachm to an ounce. 412. As an Antiseptic agent in Surgical Practice, some trials have been made with it by Sir Joseph Fayrer (Indian Med. Gazette, Sept. 1869, p. 184), and he comes to the conclusion that it possesses some, if not all, the advantages assigned to Carbolic Acid in this character. He used it, pure or diluted, with equal parts of oil or glycerine; and he states that whilst it certainly has some deodorising power, it appeared also to have that of limiting suppuration and of restraining the development of septic miasmata in the discharges. He likewise found it useful as a stimulating and detergent application to Sloughing and Ulcerated Surfaces, and in one case of Carbuncle 413. Kerosene Oil.A burning oil, refined from crude Petroleum. Pathar-ka-tÉl (Punj.). 414. Owing to the extensive use of this mineral Oil for lighting purposes during the past few years, it can now be obtained in nearly every bazaar in the country. According to the experience of Dr. Aitchison, no local remedy is so pre-eminently useful in all Skin Diseases as this, especially when of a parasitic origin. It is comparatively of little use in syphilitic eruptions. 415. The oil may be employed pure when no large surface is involved, but if the disease to be treated extensively covers the body, it should be diluted with equal parts of sweet oil. Nothing can come up to it, he asserts, in removing and destroying bugs from old wood. It is also said to be of use in removing white ants. 416. In Itch, when of limited extent, after opening 417. Rock Salt.An impure Chloride of Sodium. Senda-lon, Senda-namak (Hind., Duk.), IndÚppÚ (Tam., Tel.), IntÚppa (Mal.), NÍmak, Lun (Punj.). 418. Rock Salt occurs in large masses varying in weight from 2 or 3 to 8 or 10 lb.: dull or brownish-white externally, white and crystalline internally, of a pure saline taste; procurable in all large Indian bazaars at four or five annas per lb. Though known to be a mere variety of Chloride of Sodium (common salt) it is possessed of far stronger purgative properties, |
