Investigação científica e uso clínico da quina em Portugal na transição do século XVIII para o século XIX / Scientific research and clinical use of quinine in Portugal in the transition from the 18th to the 19th century

A quina, uma casca de árvores nativas da América do Sul do género Cinchona com propriedades antimaláricas, tem um importante lugar na história da medicina e da farmácia. Possivelmente já conhecida pelos espanhóis no século XVI, foi usada na terapêutica pela sua atividade febrífuga, estabelecendo-se como tratamento para as febres intermitentes nos séculos XVIII e XIX. Este artigo pretende avaliar a receção da quina em Portugal no último quartel do século XVIII e no primeiro quartel do século XIX através do estudo de obras portuguesas que descrevem pormenorizadamente as aplicações terapêuticas da quina, do estudo de uma publicação periódica médica, o Jornal de Coimbra e do estudo de receituário médico. Em Portugal, a quina foi também utilizada pela sua ação febrífuga, tendo sido publicadas várias obras descritivas da sua atividade terapêutica quer nas febres intermitentes, quer em doenças como a gota ou na gangrena. No periódico científico português Jornal de Coimbra (1812-1820) foram publicados, por indicação governamental, relatos de médicos de todo o país sobre as doenças existentes nas localidades em que exerciam e respetivo tratamento utilizado. Através da leitura desta publicação, verifica-se que a quina era um tratamento generalizado e normalmente eficaz para as febres intermitentes. No tratamento das febres intermitentes, a quina era geralmente associada a outros medicamentos como os eméticos. A quina foi também a droga mais prescrita num estudo de caso compreendendo 1954 receitas médicas. Foi prescrita por 434 vezes, entre 1779 e 1825, em receitas preparadas pelo Dispensatório Farmacêutico do Hospital da Universidade de Coimbra. Os relatos publicados no Jornal de Coimbra sobre a aplicação clínica da quina, e a percentagem elevada de receitas em que esta foi prescrita comprovam a sua importância na terapêutica em Portugal.

Quinine, a tree bark native to South America of the genus Cinchona, has antimalarial properties and occupies an important place in the history of medicine and pharmacy. Possibly already known to the Spanish in the 16th century, it was used in therapeutics for its febrifugal activity, becoming established as a treatment for intermittent fevers in the 18th and 19th centuries. This article aims to evaluate the reception of quinine in Portugal in the last quarter of the 18th century and the first quarter of the 19th century by studying Portuguese works that describe the therapeutic applications of quinine in detail, by studying a medical publication, the Jornal de Coimbra, and by examining medical prescriptions. In Portugal, quinine was also used for its febrifugal action, and several works were published describing its therapeutic activity in both intermittent fevers and diseases such as gout and gangrene. Acting on governmental instructions, the Portuguese scientific periodical Jornal de Coimbra (1812-1820) published reports by doctors throughout the country on diseases observed in the places where they practiced and on the treatments they applied. Reading this publication shows that quinine was a widespread and usually effective treatment for intermittent fevers, commonly combined with other drugs such as emetics. Quinine was also the most prescribed drug in a case study comprising 1,954 prescriptions. It was prescribed 434 times between 1779 and 1825 in prescriptions prepared by the Pharmaceutical Dispensatory of the Coimbra University Hospital. The reports in the Jornal de Coimbra on the clinical application of quinine and the high frequency of its prescription demonstrates its important therapeutic role in Portugal. (AU)

Plant Adaptogens-History and Future Perspectives.

Adaptogens are synthetic compounds (bromantane, levamisole, aphobazole, bemethyl, etc.) or plant extracts that have the ability to enhance the body's stability against physical loads without increasing oxygen consumption. Extracts from Panax ginseng, Eleutherococcus senticosus, Rhaponticum carthamoides, Rhodiola rosea, and Schisandra chinensis are considered to be naturally occurring adaptogens and, in particular, plant adaptogens. The aim of this study is to evaluate the use of plant adaptogens in the past and now, as well as to outline the prospects of their future applications. The use of natural adaptogens by humans has a rich history-they are used in recovery from illness, physical weakness, memory impairment, and other conditions. About 50 years ago, plant adaptogens were first used in professional sports due to their high potential to increase the body's resistance to stress and to improve physical endurance. Although now many people take plant adaptogens, the clinical trials on human are limited. The data from the meta-analysis showed that plant adaptogens could provide a number of benefits in the treatment of chronic fatigue, cognitive impairment, and immune protection. In the future, there is great potential to register medicinal products that contain plant adaptogens for therapeutic purposes.

What about Dinner? Chemical and Microresidue Analysis Reveals the Function of Late Neolithic Ceramic Pans.

The Late Neolithic palafitte site, Ustie na Drim, in the northern part of Lake Ohrid (North Macedonia), excavated in 1962, offered ceramic fragments of large, flat, elongated pans. These artifacts could be dated by relative chronology to roughly around 5200-5000 BC. According to their shape and technological traits, the ceramic pans were probably used for baking. The attached materials on the surface of studied pan fragments were sampled for consequent chemical and microscopical analyses (i.e., analyses of starch, phytoliths, and microscopic animal remains). An immunological method revealed the presence of pork proteins in samples. The presence of organic residues of animal origin was, moreover, confirmed by the detection of cholesterol using gas chromatography coupled to mass spectrometry. Analysis of detected microscopic botanical objects revealed starch grains of several plants (i.e., oak, cattail, and grasses). An interesting find was the hair of a beetle larva, which could be interpreted contextually as the khapra beetle, a pest of grain and flour. Based on our data, we suppose that the ceramic pans from Ustie na Drim were used for the preparation of meals containing meat from common livestock in combination with cereals and wild plants.

The Cannabis Spread throughout the Continents and its Therapeutic Use in History.

BACKGROUND: Cannabis sativa L. (C. sativa) is a plant whose use as a therapeutic agent shares its origins with the first Far East's human societies. Cannabis has been used not only for recreational purposes but as food to obtain textile fibers, to produce hemp paper, to treat many physical and mental disorders. AIM: This review aims to provide a complete assessment of the deep knowledge of the cannabis psychoactive effects and medicinal properties in the course of history covering i.) The empirical use of the seeds and the inflorescences to treat many physical ailments by the ancient Oriental physicians' ii.) The current use of cannabis as a therapeutic agent after the discovery of its key psychoactive constituent and the human endogenous endocannabinoid system. METHODS: This study was performed through a detailed analysis of the studies on the historical significance and medical applications of Cannabis sativa by using international scientific databases, historical and medical books, ancient Greek and Chinese manuscripts translations, library and statistical data from government reports and texts from the National Library of Greece (Stavros Niarchos Foundation), from the School of Health Sciences of the National and Kapodistrian University of Athens (Greece). We selected papers and texts focusing on a historical point of view about the medical importance of the plant and its applications for a therapeutic purpose in the past. RESULTS AND CONCLUSION: Through a detailed analysis of the available resources about the origins of C. sativa, we found that its use by ancient civilizations as a source of food and textile fibers dates back over 10,000 years, while its therapeutic applications have been improved over the centuries, from the ancient East medicine of the 2nd and 1st millennium B.C. to the more recent introduction in the Western world after the 1st century A.D. In the 20th and 21st centuries, Cannabis and its derivatives have been considered as a menace and banned throughout the world, but nowadays, they are still the most widely consumed illicit drugs all over the world. Its legalization in some jurisdictions has been accompanied by new lines of research to investigate its possible applications for medical and therapeutic purposes.

Geopolitics of bitterness: Deciphering the history and cultural biogeography of Quassia amara L.

ETHNOPHARMACOLOGICAL RELEVANCE: Quassia amara L. recently came into the spotlight in French Guiana, when it became the object of a biopiracy claim. Due to the numerous use records throughout the Guiana shield, at least since the 18th century, a thorough investigation of its origin seemed relevant and timely. In the light of the Convention on Biological Diversity (CBD) and the Nagoya protocol, questions about the origin of local knowledge are important to debate. AIM OF THE STUDY: Defining cultural biogeography as the dynamics through space and time of biocultural complexes, we used this theoretical framework to shed light on the complex biogeographical and cultural history of Q. amara. We explored in particular the possible transfer of medicinal knowledge on an Old World species to a botanically related New World one by enslaved Africans in Suriname. MATERIALS AND METHODS: Historical and contemporary literature research was performed by means of digitized manuscripts, archives and databases from the 17th to the 21st century. We retrieved data from digitized herbarium vouchers in herbaria of the Botanic Garden Meise (Belgium); Naturalis Biodiversity Center (the Netherlands); Missouri Botanical Garden, the Smithsonian National Museum of Natural History, the Field Museum (USA); Royal Botanic Gardens Kew (UK); the IRD Herbarium, French Guiana and the Museum National d'Histoire Naturelle (France). Vernacular names were retrieved from literature and herbarium specimens and compared to verify the origin of Quassia amara and its uses. RESULTS: Our exploration of digitized herbarium vouchers resulted in 1287 records, of which 661 were Q. amara and 636 were Q. africana. We observed that the destiny of this species, over at least 300 years, interweaves politics, economy, culture and medicine in a very complex way. Quassia amara's uses are difficult to attribute to specific cultural groups: the species is widely distributed in Central and South America, where it is popular among many ethnic groups. The species spread from Central to South America during the early 18th century due to political and economic reasons. This migration possibly resulted from simultaneous migration by religious orders (Jesuits) from Central America to northern South America and by Carib-speaking Amerindians (from northern South America to Suriname). Subsequently, through colonial trade networks, Q. amara spread to the rest of the world. The absence of African-derived local names in the Guiana shield suggests that Q. africana was not sufficiently familiar to enslaved Africans in the region that they preserved its names and transferred the associated medicinal knowledge to Q. amara. CONCLUSIONS: Cultural biogeography has proven an interesting concept to reconstruct the dynamics of biocultural interactions through space and time, while herbarium databases have shown to be useful to decipher evolution of local plant knowledge. Tracing the origin of a knowledge is nevertheless a complex adventure that deserves time and interdisciplinary studies.

A Brief History of Psoriasis Management in Canada.

Psoriasis is a chronic, inflammatory disease with a varying degree of clinical presentations. Managing psoriasis has always been arduous due to its chronicity and its propensity to relapse. Prior to the development of targeted biologic therapies, there were few effective treatments for psoriasis. Ancient psoriasis therapies included pinetar, plant extracts, psychotherapy, arsenic, and ammoniated mercury. In the 19th century, chrysarobin was developed. Then, in the early half of the 20th century, anthralin and coal tar were in widespread use. In the latter half of the 20th century, treatments were limited to topical first-line therapies, systemic drugs, and phototherapy. However, as the treatment of psoriasis has undergone a revolutionary change with the development of novel biologic therapies, patients with moderate to severe psoriasis have been able to avail therapies with high efficacy and durability along with an acceptable safety profile. This article is a brief historical review of the management of psoriasis prior to the inception of biologics and with the development of novel biologic therapies.

Inventing a herbal tradition: The complex roots of the current popularity of Epilobium angustifolium in Eastern Europe.

ETHNOPHARMACOLOGICAL RELEVANCE: Currently various scientific and popular sources provide a wide spectrum of ethnopharmacological information on many plants, yet the sources of that information, as well as the information itself, are often not clear, potentially resulting in the erroneous use of plants among lay people or even in official medicine. Our field studies in seven countries on the Eastern edge of Europe have revealed an unusual increase in the medicinal use of Epilobium angustifolium L., especially in Estonia, where the majority of uses were specifically related to "men's problems". THE AIM OF THE CURRENT WORK IS: to understand the recent and sudden increase in the interest in the use of E. angustifolium in Estonia; to evaluate the extent of documented traditional use of E. angustifolium among sources of knowledge considered traditional; to track different sources describing (or attributed as describing) the benefits of E. angustifolium; and to detect direct and indirect influences of the written sources on the currently documented local uses of E. angustifolium on the Eastern edge of Europe. MATERIALS AND METHODS: In this study we used a variety of methods: semi-structured interviews with 599 people in 7 countries, historical data analysis and historical ethnopharmacological source analysis. We researched historical and archival sources, and academic and popular literature published on the medicinal use of E. angustifolium in the regions of our field sites as well as internationally, paying close attention to the literature that might have directly or indirectly contributed to the popularity of E. angustifolium at different times in history. RESULTS: Our results show that the sudden and recent popularity in the medical use of E. angustifolium in Estonia has been caused by local popular authors with academic medical backgrounds, relying simultaneously on "western" and Russian sources. While Russian sources have propagated (partially unpublished) results from the 1930s, "western" sources are scientific insights derived from the popularization of other Epilobium species by Austrian herbalist Maria Treben. The information Treben disseminated could have been originated from a previous peak in popularity of E. angustifolium in USA in the second half of the 19th century, caused in turn by misinterpretation of ancient herbals. The traditional uses of E. angustifolium were related to wounds and skin diseases, fever, pain (headache, sore throat, childbirth), and abdominal-related problems (constipation, stomach ache) and intestinal bleeding. Few more uses were based on the similarity principle. The main theme, however, is the fragmentation of use and its lack of consistency apart from wounds and skin diseases. CONCLUSIONS: Historical ethnobotanical investigations could help to avoid creating repeating waves of popularity of plants that have already been tried for certain diseases and later abandoned as not fully effective. There is, of course, a chance that E. angustifolium could also finally be proven to be clinically safe and cost-effective for treating benign prostatic hyperplasia, but this has not yet happened despite recent intensive research. Documented traditional use would suggest investigating the dermatological, intestinal anti-hemorrhagic and pain inhibiting properties of this plant, if any.

Anti-Oxidant in China: A Thirty-Year Journey.

Anti-oxidant refers to such a kind of endogenous or exogenous compound that is able to retard or even prohibit in vivo or in vitro oxidation with only small amount being used. The study of anti-oxidants starts nearly 30 years ago, and the research on this topic in China almost begins simultaneously with that in the world. Gratifyingly, contributions on anti-oxidants from China researchers have rapidly increased in the recent decade as anti-oxidants have become a hot topic in biochemistry, pharmacology, food science, chemistry as well as other related disciplines. Anti-oxidants provide a specific viewpoint for clarifying pharmacological effects of Chinese medicinal herbs. For example, as a traditional Chinese medicinal herb, Panax ginseng C. A. Meyer is found to be a natural anti-oxidant resource. Meanwhile, some signaling pathways such as nuclear factor-κB (NF-κB), nuclear factor erythroid 2 related factor 2 (Nrf2), and Kelch-like ECH associated protein 1 (Keap1) are regarded to play an important role in anti-oxidant responses. These findings provide a substantial basis for understanding the pharmacological behaviors of Chinese medicinal herbs in view of regulating the aforementioned signaling pathways. Moreover, inhibition of reactive oxygen species (ROS) by supplementation of anti-oxidant becomes a popularly accepted idea in keeping health and treating diseases. Isolations of antio-xidative ingredients from medicinal herbs and foods lead to set up a large range of anti-oxidative compound libraries, and intake of anti-oxidants from foods may be the most efficient way for supplementing exogenous anti-oxidants. On the other hand, designing anti-oxidants with novel structures motivates organic and medicinal chemists to explore the structure-activity relationship, and then, to find novel structural features with anti-oxidative properties. Therefore, it is reasonable to believe that China researchers will donate more endeavors to obtain more achievements on anti-oxidants in the future.

Liquorice (Glycyrrhiza glabra): the journey of the sweet root from Mesopotamia to England.

Liquorice is a very ancient plant widely used in the East for millennia. It has often been employed in sweets and confectionery and also for minor ailments including cough, constipation and dyspepsia. It was probably carried to Europe by the Cluniac order of monks. Then, almost by accident, it became established in West Yorkshire at Pontefract after the dissolution of the monasteries in the 1530s. Abuse of liquorice is not uncommon. It can occur in the anorexia/bulimia syndrome and also in the dangerous condition of pseudoaldosteronism, which is characterised by severe hypertension and hypokalaemia and can lead to death. Liquorice remains a useful sweetener for all sorts of confectionery, including sweets and cakes (together with beer and liqueurs).

Phytochemistry and pharmacology of the genus Entandrophragma over the 50 years from 1967 to 2018: a 'golden' overview.

OBJECTIVES: For centuries, the genus Entandrophragma (Meliaceae), endemic to Africa, has been used in traditional medicine for the treatment of several illnesses. This review deals with large range of phytochemicals from the genus Entandrophragma and their pharmacological potentials covering the period from 1967 to 2018. KEY FINDINGS: Phytochemical investigations of the genus Entandrophragma led to the report of about 166 secondary metabolites which have been thoroughly summarized herein including some of their semisynthetic derivatives obtained from chemical transformations as well as their biological activities in the medicinal and agricultural domains. The limonoids or meliacins and their precursor called protolimonoids (protomeliacins) reported so far represent almost 69.28% of the total secondary metabolites obtained from the genus, and they display the most potent biological activities. Collectively, both classes of metabolites constitute the markers of Entandrophragma. However, squalene-type triterpenoids and sesquiterpenoids were reported only from the species E. cylindricum and therefore could be its chemotaxonomic markers. SUMMARY: The pharmacological investigations of the extracts of some species exhibited interesting results which support the traditional uses of these Entandrophragma plants in folk medicine. Some compounds revealed promising antiplasmodial and anti-inflammatory activities and deserve therefore further attention for new drug discovery.

Ancient treatment for lice: a source of suggestions for carriers of other infectious diseases?

Louse infestation is one of the oldest contagious pestilential diseases of humankind, which has recently re-emerged in several developing countries as well as in homeless individuals and migrants. The present work provides the first phase of an historical excursus of louse remedies based on the classics of pharmaceutical literature, codes, pharmacopoeia and treatises. The second phase involves a literature search, based on the principal medical databases (SciFinder, Pubmed, Google Scholar, ISI-Web of Science and Scopus), to match ancient raw materials and active principles for the treatment of pediculosis and their possible applications, with other current infectious pathologies transmitted by different carriers. In this regard, Rhododendron tomentosum has revealed repellent insect activity, particularly against Aedes aegypti, responsible for Dengue fever, Chikungunya, Zika fever, Mayaro, yellow fever and other infectious diseases. Petroselinum crispum is an insecticide employed for resistant strains of A. aegypti. In the case of Delphinium staphisagria, the phytochemical profile was further investigated with the identification of further molecules in addition to delphinine. The latter shows interesting activities against Trypanosoma cruzi and Leishmania. Anthemis pyrethrum, now renamed as Anacyclus pyrethrum, although not containing pyrethrins present in several plants of the genus Chrysanthemum, revealed pediculicidal activity but did not produce satisfactory results in antiprotozoal activity.

Tecnociencia y colonialismo en la historia de las Cinchona / Technoscienci and colonialism in the history of the Cinchona

En este artículo se reflexiona sobre la ciencia y tecnología (o tecnociencia) asociadas con el colonialismo. Se usa la metáfora de "capas de colonialismo" para aludir a ideas y prácticas asociadas con la tecnociencia que son continuamente innovadas, que pueden mantenerse o reaparecer en diferentes momentos, y que estructuran el hecho colonial. Se usa como caso la apropiación de plantas de quina (Cinchona spp.) en diferentes momentos entre los siglos XVI y XX. Algunas de las capas presentadas son: apropiación material del producto natural, deslocalización y relocalización del lugar de autoridad alrededor del mismo, soterramiento de los saberes y sabedores locales, inserción de ideas sobre lo que se debe hacer con esa naturaleza, quién y cómo debe apropiarla, no-transferencias de tecnología, fomento de proyectos sin mayores oportunidades, entre otras. En la historia de larga duración del colonialismo alrededor de la apropiación de las quinas, se enfatiza en capas que emergen o reemergen en momentos clave

This article reflects on the science and technology (or technoscience) associated with colonialism. The metaphor of "layers of colonialism" is used to refer to ideas and practices associated with technoscience that are continuously innovated, that can be maintained or reappear at different times, and that structure the colonial fact. The appropriation of quina plants (Cinchona spp.) is used as a case at different times between the 16th and 20th centuries. Some of the layers presented are: material appropriation of the natural product, dislocation and relocation of the place of authority around it, burial of local knowledge and it's owners, insertion of ideas about what to do with that nature, who and how to appropriate it, non-transfers of technology, promotion of projects without greater opportunities, among others. In the long history of colonialism around the appropriation of the quinas, emphasis is placed on layers that emerge or reemerge at key moments

"Bunanje": XX Century Abuse of Atropa Belladonna Halucinogenic Berries in Continental Croatia.

BACKGROUND: Atropa belladonna (Engl. deadly nightshade, Cro. velebilje, bunika) is a plant containing pharmacologically active, potentially toxic alkaloids: atropine, hyocyamine and scopolamine. The risk of poisoning in children is important because of possible confusion of black/dark blue belladonna fruit berries with other edible berries. There are many reports in literature of accidental intoxication but no report on traditional intentional usage to achieve hallucinogenic effects. SUBJECTS AND METHODS: Here we report purposeful ingestion of Atropa belladonna berries for hallucinatory effects among adolescents in Bjelovar region in north part of Croatia. This has been happening among children/adolescents while they were grazing animals. We visited a dozen villages in the region and spoke to the oldest mostly to the elderly residents. RESULTS: The existence of such abuse of Atropa belladonna berries in the first part of XX century was confirmed by eight narrators from five distinct places in the region. Interestingly this type of behavior had a specific name "bunanje", unknown in Croatian language, but clearly associated with local plant name bun or bunika. According to informants consumers of berries would develop delirium or hallucinations associated behavior, incoherent and meaningless speech. However nobody remembers any severe case of poisoning. At the regional hospital in Bjelovar in the Pediatric department, there is no record of poisoning with Atropa belladonna. To our knowledge this is the first report of intentional consumption of belladonna berries to achieve the hallucinogenic effect. CONCLUSIONS: The fact that the custom was observed in five distinct spots and it had its specific name "bunanje" suggest that those are not isolated random events but the type of practices; seasonal abuse of hallucinogenic berries of Atropa belladonna, among rural adolescents in the first part of XX century.

The Chemical History of Morphine: An 8000-year Journey, from Resin to de-novo Synthesis.

Evidence of human use of opium dates back as far as the sixth millennium BCE. Ancient societies through the Renaissance period created a variety of opium products, proliferating its common use and subsequent addiction. Because the active moiety was not known at this time, the potency of these opium concoctions could neither be predicted nor controlled. The first step in identifying opium's active ingredient, morphine, was its chemical isolation in the early 1800s by Wilhelm Sertürner. The subsequent elucidation of morphine's chemical formula and Sir Robert Robinson's derivation of morphine's structural formula, which won him the 1947 Nobel Prize in Chemistry, round out 150 years of the incremental advances in our chemical understanding of morphine. Nevertheless, our attempts to synthesize morphine, despite our advanced knowledge in synthetic chemistry, are still no match for the plant-based extraction of morphine from the poppy plant. The status quo remains problematic socially, economically, and politically; the relationships between the countries laboriously growing poppy plants to extract morphine and those countries importing these painkillers are unstable at best. In this study, we contrast the cumulative scientific discoveries that have led to our current chemical knowledge of morphine with the centuries-old natural method of morphine production that still dominates the opioid market today.

Medicinal Plants Targeting Cardiovascular Diseases in View of Avicenna.

BACKGROUND: Cardiovascular disease (CVD) is a spectrum of diseases involving the heart and blood vessels, and the first cause of mortality worldwide. Medicinal plants have been used for thousands of years to treat CVD. In Traditional Persian Medicine (TPM), there is a special focus on heart diseases. Avicenna, a Persian physician of the eleventh century compiled a book devoted to this field named "The treatise on cardiac drugs" which is a compendium of TPM knowledge on CVD. Avicenna mentioned 50 cardiovascular active plants and described their therapeutic effects in the treatment of CVDs. METHODS: Here, we perform a detailed search in scientific databases to verify the cardiovascular activities of the medicinal plants suggested by Avicenna. Also, we discussed cardiovascular activities of a number of the most important suggested plants as well as their efficacy in clinical studies. Major bioactive compounds identified from these plants are also discussed. RESULTS: Pharmacological studies have revealed that the majority of these plants are effective in cardiovascular health with various mechanisms. Among them, Crocus sativus L., Cinnamomum cassia (L.) J. Presl, Punica granatum L., Ocimum basilicum L., Elettaria cardamomum (L.) Maton, Melissa officinalis L. and Phyllanthus emblica L. have proved to be more effective. CONCLUSION: The above-mentioned plants can be rich sources for developing new and effective pharmaceuticals for the treatment of CVDs.
