The bark can be taken in the form of a tincture, decoction, or infusion. London: D Wilson. Although he debated questions of dosage and presentation of quinine (p 429-430), however, he stuck to what he referred to as “my rather conspicuous experience” (p 432). Proceedings Koninklijke Akademie van Wetenschappen 35:911-914. Marchoux E (1933). The Slave Trade Act (1807) had forbidden the importation of African slaves to British colonies. La malaria in Italia durante il 1902. From the end of the 19th century, when the life cycle and vector of malarial parasites were identified, other antimalarial interventions were deployed beyond drugs, including, for example, approaches to limit breeding places for mosquitoes; provide physical protection of buildings and people against the insects; and to deploy anti-larval and anti-mosquito procedures, such as petrol, larvivorous fish, and Paris Green as a pesticide. Quinine and quinidine are also antispasmodic, making the bark potentially useful for treating muscle cramps as well. My procedure is directed to towards the parasites in the infected men. Side effects can be deadly and damage the heart severely. The treatment of several diseases, formerly based on the use of crude plant extracts, could now be examined on a more quantitative basis. Add cinchona bark, herbs and spices to the water and boil for ten minutes, stirring occasionally. Free quinine pills were distributed to the rural populations by physicians. Maitland CB (1900). The very end of the 19th century was a turning point in parasitology in general and malariology in particular. This James Lind Library article (Part 1 and 2, has been republished in the Journal of the Royal Society of Medicine 2017;110:31-40. Fletcher W (1925). Researches on the treatment of benign tertian fever. Peruvian Bark – China. Koch’s stay in New Guinea from 29 December 1899 till 8 August 1900 proved decisive for his future statements about the control of malaria. In Willcox M, Bodeker G, Rosoanaivo P, eds. France and French armed forces are surprisingly absent from the debate on quinine as a prophylactic agent. Volkmann’s Sammlung Klinische Vortraege N.F. Ferroni E, Jefferson T, Gachelin G (2011). Facts like these are not to be mistaken; the previous pages of this report contain many others of nearly equal value. This factor had been emphasized in 1914 in a review of quinine prophylaxis by a senior surgeon in the United States Public Health Service (Carter 1914). Plasmoquine prophylaxis in benign tertian malaria. (Bryson 1847, p 218). 2006). New Haven, CT: Yale University Press. Cook H (2010). The first patient and all those bearing odd numbers were given quinine; those with even numbers (i.e. Die Bekämpfung der Malaria (Fighting Malaria). Accessed 15-3-16 at http://edoc.rki.de/browsing/rki_rk/. 2014). I have to stress this explicitly. In the early 1890s Koch had developed and successfully applied a strategy against cholera focusing on the isolation and elimination of the causative agent, the parasite vibrio cholerae. London: Kegan Paul, Trench, Trübner, pp 180-181. Journal de Pharmacie, 128-133. The dose of quinine used in 1820 and in later studies appears to have been adapted from the quantity of bark powder previously used for intermittent fevers. His experimental community was the German plantation site of Stephansort (Koch 1900), which had 734 inhabitants and two “hospital houses” (one for the roughly five dozen Europeans [GW 2, 1, p …], the other for the natives). Report about malaria prophylaxis and treatment with atebrine. Koch’s intensive involvement in attempts to control malaria appear to have begun in 1898, when he asked his administrative superior, the Prussian minister of religious, education and medical affairs, for money to fund an expedition to Italy and the Dutch Indies (GW 2: 2, p 883-887). Some of the Italian case series he quoted included up to 64 patients with different forms of severe intermittent fevers. A drug used in Japan for the treatment of influenza called Favipiravir or Avigan seems to be also effective for treating COVID-19. Cinchona bark had been included in the Navy medicine chest in 1814; the Admiralty began issuing regulations on fevers in 1816; quinine replaced bark in the medicine chest in 1830; and a Royal Navy department of statistics was created in 1831 to gather observations contained in ships’ log-books (Mitcham 2010). Ephraim A (1890). The bark of the tree, from which the homeopathic remedy China is prepared, contains quinine. Studies from the Institute for Medical Research, Kuala Lumpur, Federated Malay States No.18. Parte II: Profilassi della malaria. The accumulation of personal experiences, whether in America, Africa or Asia, led to the conclusion that quinine sulphate – as pills or as quinine wine, in doses of between 3 and 5 grains a day – was effective in preventing malaria. Narrative of an exploring voyage up the rivers Kwo’ra and Bi’nue. They were treated immediately and cured. Zeitschrift für Hygiene und Infektionskrankheiten. In addition, the physical condition of sailors and marines may also have improved as a result of better sanitary conditions aboard, particularly the quality of drinking water, an improvement largely reflecting the opinion that malaria was caused by a water-borne or an air-borne ‘poison’ (Watt 2002). Cinchona bark contains the bitter alkaloids quinine, quinidine, cinchonidine and cinchonine, as well as the bitter glycoside, quinovin. Ferez S (2003). Studies in Malaria, with special reference to Treatment. Rocco F (2004). However, as illustrated by a controlled comparison of the two drugs reported in 1932 (Sanders and Dawson 1932), uncertainties about their relative merits persisted; and even today, quinidine remains a parenteral drug used for severe malaria in the USA, where quinine is often not available (White et al. Clinical experiments, histories and dissections. Naval. Elliotson J (1823). Medical Research Council (1925). the second and alternate patients) were given quinidine. Celli had previously reported on his controlled evaluation of physical measures to protect Italian railway workers and their homes from mosquitos (Celli 1900a; 1900b; Ferroni et al. Dymock and his colleagues do not report whether the Commission’s ‘experiments’ were ‘natural’ or ‘planned’. Walker, K., & Nesbitt, M. (2020). 2011; Ramanna 2014). Bulletin of the Health Organisation of the League of Nations 6:236-290. Lind J (1768). Cinchona. Malaria Commission CH/Malaria/193. The most common side effect of a toxic dose of quinine is cinchonism. The dose of quinine is quite small in tonic water, and one would need to consume over 6 liters of tonic water to obtain one therapeutic dose of quinine. JLL Bulletin: Commentaries on the history of treatment evaluation (https://www.jameslindlibrary.org/articles/testing-the-effects-of-jesuits-bark-in-the-chinese-emperors-court/). On the prophylactic influence of quinine. Comments: -This drug has been effective in geographical regions with documented chloroquine resistance. 31. “My procedure is something completely different. Cinchonism – a combination of tinnitus, high-tone hearing impairment and nausea – was clearly defined by Magendie (1822) after he had administered pure quinine to dogs and later to patients. Lind J (1776). Revue d’hygiène et de police sanitaire 18:223-240. Quinidine in falciparum malaria. Modena: B Soliani. 2. After 1800, improvement in procedures for acid-base extraction of the active principles of medicinal plants yielded a number of purified molecules of medical interest. in Brewing & Distilling from Heriot-Watt University, a Professional Certificate in Cannabis Science & Medicine from University of Vermont’s College of Medicine and is currently pursuing a M.S. Koch’s method was initiated by Ollwig in Daressalam in 1901-1903 (Ollwig 1903) and appears to have continued at least until 1914 (Orenstein 1914), was reported as having been “successful in so far as it has at least considerably reduced the incidence of malaria.” Yet, in the longer term, Koch’s approach did not seem to have worked consistently. Sinton JA, Bird W (1929). As in other spheres at the time (Chalmers et al. Des quinquinas et des questions qui dans l’état present de la science et du commerce s’y rattachent avec le plus d’actualité. Uses 1. Comparison with past clinical experience and the rapidity of the response to both Cinchona bark and quinine in many reported cases and case series left comparatively little room for doubt that the drug had beneficial effects on the disease. Hicks EP, Diwan Chand S (1935). He stated the advantages of quinine over bark as follows: “Quinine is nothing but the new form of an old medicine, but presented in such a way that no intermittent fever can resist it… It is very true that Quinine and Cinchonina cannot strictly be called new medicines, because they exist, one or both, in the Cinchona which we have all been prescribing. In order to incorporate the compound into a water-based beverage, either quinine hydrochloride or quinine sulfate salts are typically used. As, for example; if the bark should fail of curing an ague, or mercury of removing a venereal taint, are we thence rashly to conclude, that either of those medicines will prove, in all other instances and cases, ineffectual? Description, Medical Uses, and Dosage. Pelletier J, Caventou JB (1821). Indian Journal of Medical Research 16:725-746. Paris, Blageart / D’Houry. 2011), alternation was increasingly adopted during the 1930s as a feature of controlled comparisons of alternative anti-malarial treatments. The medicine became known, among other names, as Cortex peruanus, or Jesuit’s powder, since it had been imported into Europe from Latin America by the Loyola Order. Studies in Malaria, with special reference to treatment. The conclusions with respect to mass drug prophylaxis were even more sobering. Annali di Igiene Sperimentale 13:322-343. Whereas the efficacy of Cinchona bark and quinine for treating intermittent fevers had become widely accepted by the turn of the 18th and 19th centuries, their role in preventing fevers had not been convincingly established. The administration was repeated, usually no more frequently than twice a day, until complete disappearance of rigors. Since 1891 he had directed the huge Institut für Infektionskrankheiten created for him in Berlin. Rice and beri-beri: preliminary report on an experiment conducted in the Kuala Lumpur Insane Asylum. Magendie notes that several authors reported using quinine to treat or alleviate a variety of non-malarial diseases – ulcers, haemorrhoids, gastric inflammation, intermittent neuralgia, and haemoptysis, for example. Of these 2472 cases, 2,445 were cured and 27 failed. Analyse chimique des quinquinas. Methylene blue in malarial fever. Cinchona Powder:- 0.3 to 1 gm. London: Samuel Highley. The interaction of scientific evidence and politics in debates about preventing malaria in 1925. Report CH273. The crews of some non-military vessels were protected using prophylactic quinine. Lind does note in the book that: …[U]pon an eclipse of the moon, the English merchants and others who had left off taking the bark, suffered a relapse…and recommends that bark should be taken at the full and change of the moon, as being the seasons most dangerous for an attack or relapse into those intermitting fevers (Lind 1768, pp 81-82). daily for 5 days. If ethanol is used as a solvent, is can be easily evaporated off through the application of heat, such as when reducing the solution down to a syrup. New ed. The outcome of the treatment was compared to previous experience of treatment with bark extracts, or to what was known to occur in the absence of treatment. References to the Daressalam experience in Ross’s book and elsewhere, and Manteufel’s statistics, prompted AJ Orenstein – whose principal duty in Daressalam had been to institute a campaign against malaria – to report his test of Koch’s theory that malaria could be eradicated by attacking the parasite within the human host (Orenstein 1914). At the first site there had been no outbreak of malaria during dyke building works at Wilhelmshaven; at Brioni (Croatia) malaria had been eradicated; and in Daressalam, “the number of those ill with malaria had decreased by more than 50%” (p 895). Additionally, because they are similar in structure and bioactivity, their side effects can be compounded by the consumption of quinine. 100 capsules per bottle – it is more than 10% free compared to the previous packaging. (https://archive.org/stream/annalidigienesp01unkngoog#page/n328/mode/2up). The powdered bark is often used in tooth-powders, owing to its astringency, but not much used internally (except as a bitter wine); it creates a sensation of warmth, but sometimes causes gastric intestinal irritation. The appropriate dose of cinchona depends on several factors such as the user's age, health, and several other conditions. Guttmann P, Ehrlich P (1891). In 1908 he added that nets might be tried in the colonies “in order to prevent the possible reproach of an omission” (p 897). Van Buren, in the name of the Sanitary Committee, wrote: In conclusion, it may be fairly assumed, even from the evidence thus imperfectly and hastily collated, that the power of Quinine as a preventive of miasmatic disease, is fully established as a medical fact; and that it can be employed, not only with entire safety, but with the greatest advantage, even to the saving of life, by healthy persons exposed to malarial influences. Also, search for less expensive alternatives to Cinchona contributed to market confusion. 7 (1707): pp. Indeed, quinine remained unchallenged for a further half century, when controlled trials showed that artemether and artenusate – which had also been derived from plants and used to treat fever (Tu 2011) – were shown to be superior to quinine in treating severe malaria (Sinclair et al. Lancet 1:1776-1779. It sounds sensible to institute experiments under the following conditions. JLL Bulletin: Commentaries on the history of treatment evaluation (https://www.jameslindlibrary.org/articles/four-early-clinical-studies-to-assess-the-effects-of-peruvian-bark/). Paris: G Baillière. Despite all these advances, the disease still remains a cause of widespread poor health in many tropical areas. London: HMSO, pp 5-16. From the beginning of the 18th century, however, malaria gradually emerged – from at least 128 different fevers recorded between 1774 and 1794 by Vicq d’Azyr (Peter 1972) – as a distinct clinical entity within the still complex group of intermittent (periodic) fevers (Alibert 1804). Cinchona extracts and purified alkaloids thereof (predominantly quinine, but not exclusively) remained the only effective antimalarial treatment until the early twentieth century. Symptoms can include tinnitus, hearing impairment, headache, nausea, vomiting, diarrhea, visual disturbances and postural hypotension. Alternation was also used in some of the comparisons of quinine with new synthetic antimalarial drugs in studies organised under the aegis of the Malaria Commission of the League of Nations (1937). 1937). Based on notes taken out of ships’ log books, similar conclusions were reached a few years later by a US Sanitary Commission (1861) based on reports such as the following: “During our stay in the river Lagos, quinine wine was regularly offered to the men, morning and evening — all took it, I believe, except two mid-shipmen and two seamen belonging to the galley. During the 18th century, albeit with some continuing ambiguity (Coster 1829), malaria gradually became accepted as a defined set of intermittent fevers responding to ‘therapeutic tests’ using Cinchona bark, or, from, from the 1820s, by using quinine. In the second part of a paper devoted to malaria in Italy in 1902, Celli describes a large scale experiment on malaria prophylaxis using quinine (Celli 1903). We have been unable to locate these words in the 1768 edition of ‘scurvy’ Lind’s ‘An essay on diseases incidental to Europeans in hot climates’ (Lind 1768). Case studies published after 1830 report hearing loss, headaches, vertigo, disturbances of vision, bradycardia, and digestive problems. Koch’s work in Italy appears to have continued until at least 1903, and although some letters about it were published, these do not provide any basis for strong inferences about the success of Koch’s malaria control methods there. We have seen malaria gradually disappear from temperate climates by the 1950s. Choksy NH (1900). Traditionally, the bark is prepared as a decoction taken at a dosage of half a cup, 1 to 3 times daily. —This preparation contains all the alkaloidal principles of cinchona, and has a rich deep red-brown color. Louis XIV et le quinquina. Elliotson tended to prefer the free base of quinine because it involved fewer preparation steps and so was less expensive. Bulletin of the Health Organisation of the League of Nations 6:822-891. de Blégny N (1680). These discoveries provided a rationale for improving the use of quinine for prophylaxis. Although neither bark nor quinine has the power of preventing the germs of fever from lodging in the system, there they may lie dormant for a period of from fourteen to twenty days or even longer, nevertheless, from their peculiar antagonistic properties, they most decidedly have the power in many instances of preventing their development in pyrexial action.
