Avicenna's views on pest control and medicinal plants he prescribed as natural pesticides.

The present study aimed to introduce Avicenna's views on pest control and the medicinal plants he proposed as natural pesticides. Also, we addressed the strategies that he leveraged to formulate and prescribe them, and, finally, we put his views into perspective with modern science. The data were collected using Al-Qanun Fi Al-Tibb (The Canon of Medicine) as well as scientific databases. According to Al-Qanun Fi Al-Tibb, 42 medicinal plants are described as natural pest control agents. After introducing the pest control properties of each plant, Avicenna explained the appropriate strategies for use of these plants. These strategies or formulations included incensing, spraying, spreading, rubbing, smudging, and scent-dispersing, which are equivalent to the modern pesticide formulations of fumigants, aerosols, pastes and poisoned baits, lotions, creams, and slow-release formulations, respectively. This study revealed that Avicenna introduced the pest control approach with natural plants in his book Al-Qanun Fi Al-Tibb and, thus, harnessed the power of nature to control nature. Future research is recommended to find the pest control merits of the presented medicinal plants, in order to incorporate them into pest control programs and reduce environmental pollution resulting from the complications of current synthetic pesticides.

Pattern of bioterrorism in ancient times: lessons to be learned from the microbial and toxicological aspects.

The current research aimed to analyze the history of bioterrorism in antiquity and to adapt the data to modern medical knowledge. To this end, a thorough evaluation of the literature related to the ancient history of bioterrorism and modern data was done using the Web of Sciences, Science Direct, Scopus, PubMed, and Google Scholar. Results showed that knowledge of bioterrorism has existed since antiquity in different civilizations. Biological and toxicological agents were used as an instrument of legal execution, as a warfare tool in battles, or to eliminate political rivals across nations. Ancient people researched bioterrorism to apply it against enemies and at the same time provide countermeasures in favor of themselves and allies. Despite the existence of the principles of bioterrorism since ancient times, adaptation of the data to modern research can assist in planning countermeasure efforts, preventive actions, and treatments in the framework of modern counterterrorism medicine.

Rhazes's methodology in the science of toxicology.

INTRODUCTION: Toxicology has been one of the most important topics throughout the history of medicine. Persian medicine (PM) textbooks such as Al-Hawi fi Al-Tib of Rhazes (Razi) can be a useful source for novel information about toxicology and thus we aimed to elucidate Rhazes's methodology in toxicology based on this textbook. METHODS: This research is a historical descriptive study. Data were obtained from the book Al-Hawi fi Al-Tib using keywords of poison, poisoning, and relevant terminologies in ArabicAQ1, Persian, and English and also from appropriate literature in PubMed, Scopus, Web of Science, Scientific Information Database (SID), Magiran, and IranDoc. RESULTS: After introducing the types of common poisons in his era, Rhazes categorized them into three main categories of plants, animals, and minerals, which cause human poisoning orally or via stings and bites. To identify the poison and make a diagnosis of the corresponding toxidrome, he conducted a thorough physical examination of the patient, carefully observing signs and symptoms, and then treated the poisoning using pharmaceutical and non-pharmaceutical modalities. In the book Al-Hawi fi Al-Tib, Rhazes has provided comprehensive information about the types of poisons, their effects on the human body, the signs and symptoms of poisonings, and relevant diagnostic and therapeutic methods. DISCUSSION: Rhazes had a great contributing role to the science of toxicology. We suggest future research on an in-depth analysis of other PM references for toxicology knowledge and how they may foster the science of toxicology.

Avicenna's clinical toxicology approach and beneficial materia medica against oral poisoning.

Considering the rich background of Persian Medicine in the use of materia medica for the treatment of diseases, the huge burden of oral poisonings in the world, and the urgent need to find scientific solutions, the purpose of this study was to determine Avicenna's approach toward clinical toxicology and his proposed treatments for oral poisonings. In Al-Qanun Fi Al-Tibb, Avicenna addressed the materia medica for the treatments of oral poisonings after explaining the ingestion of different toxins and also elucidating the clinical toxicology approach toward poisoned patients. These materia medica were from different classes including emetics, purgatives, enemas, diaphoretics, antidiarrheals, inhaled drugs, sternutators, anticoagulants, antiepileptics, antitussives, diuretics, cooling drugs, stimulants, cardiotonic drugs, and heating oils. By applying different therapies, Avicenna endeavored to attain main goals in clinical toxicology that are comparable with modern medicine. They included removing the toxins from the body, decreasing the severity of the deleterious effects of toxins on the body, and counteracting the effects of toxins inside the body. Aside from introducing different therapeutic agents that played an important role in the treatment of oral poisonings, he emphasized the ameliorating effects of nutritive foods and beverages. Further research using other Persian medical resources is recommended to elucidate the applicable approaches and treatments for different poisonings.

Analyzing the biological traits of snakes in Avicenna's Canon of medicine and making a comparison with contemporary serpentology.

Snakes are a group of reptiles in the order of squamata that have been the subject of scientific research for years. This study aimed to determine the biological characteristics of snakes that were mentioned in Avicenna's Canon of Medicine to compare with modern serpentology. Data were obtained from the Canon of Medicine using keywords concerning snakes and also appropriate literature in PubMed, Scopus, Web of Science, Scientific Information Database (SID), and IranDoc. Our results revealed that Avicenna divided snakes into three classes including highly, moderately, and slightly venomous snakes that are comparable to modern serpontology. Moreover, Avicenna clarified physiological factors such as age, gender, size, psychological state, hunger state, physical features, the type of living climate, habitat, and the time of snakebite. Considering the snake features presented in the Canon of Medicine, even though is not feasible to make a full comparison between Avicenna's snake knowledge and modern serpentology but some characteristics can be still applicable. Conclusively, the present study suggested that the criteria used for the identification and classification of snakes have changed from the medieval ages to the nowadays.

Avicenna's pharmacopeia for the treatment of animal bites.

Envenomation is a common medical problem. The Canon of Medicine written by Avicenna is one of the reliable sources of Persian medicine. The present study aims to identify Avicenna's clinical pharmacology approach and the pharmacopeia used for the treatment of animal envenomations and also to evaluate the related data in light of the current medicine. The Canon of Medicine was searched using related Arabic keywords for the contents about the treatment of animal bites. A literature search was conducted in scientific databases including PubMed, Scopus, Google Scholar, and Web of Science to obtain relevant data. Avicenna recommended one hundred and eleven medicinal plants for the treatment of bites of vertebrate and invertebrate venomous animals including snakes, scorpions, spiders, wasps, and centipedes. He mentioned different methods of administrating these drugs including oral drugs, lotions, sprayed drugs, slow-dissolving tablets in the mouth, and enemas. Moreover, he paid special attention to pain relief in addition to specific treatments for animal bites. In the Canon of Medicine, Avicenna recommended several medicinal plants alongside analgesics for the management and treatment of animal envenomations. The current research elucidates the clinical pharmacology and pharmacopeia of Avicenna for the treatment of animal envenomations. Further research is encouraged to evaluate the efficacy of these therapeutic agents for the treatment of animal bites.

Effects of Komouni Formulation (Herbal Product of Persian Medicine) With a Low-Calorie Diet on Cardiometabolic Risk Factors in Overweight and Obese Women: A Triple-Blinded Randomized Clinical Trial.

Background: The prevalence of obesity has almost tripled since 1975, and obesity places a heavy economic burden on healthcare systems. There is a high tendency to use a variety of complementary medicine modalities for weight management among obese patients. Persian Medicine is an ancient medical school practiced for thousands of years in Iran. Found in reliable Iranian traditional resources, Komouni formulation (KF) is a compound medicine that can be effective in the treatment of obesity. It comprises black caraway (Bunium persicum Boiss.), anise (Pimpinella anisum L.), fennel (Foeniculum vulgare Miller), and ajwain (Trachyspemum ammi L.). Objectives: This study aimed to determine the effects of KF on anthropometric indices and metabolic parameters in overweight and obese women. Methods: This triple-blinded randomized controlled clinical trial was performed on 70 overweight or obese women aged 20 - 40 years, with a body mass index (BMI) of 25 - 34.9 kg/m2. The subjects were randomly divided into two groups (each group n = 35) to receive a calorie-restricted diet with 2 g/day (500 mg 30 minutes before breakfast, 1000 mg 30 minutes before lunch, and 500 mg 30 minutes before dinner) KF or placebo for 8 weeks. Anthropometric indices, food intake, and biochemical parameters were measured at baseline and after the intervention. Results: A total of 60 women (intervention = 30; placebo = 30) completed the trial. After the intervention, the KF group experienced a significant reduction in weight (-4.8 vs. -3.2 kg; P = 0.0001), BMI (-1.8 vs. -0.79 kg/m2; P = 0.0001), waist circumference (-5.28 vs. -3.20 cm; P = 0.004), hip circumference (-0.018 vs. -0.008 cm; P = 0.047), fasting blood sugar (-5.6 vs. 0.33; P = 0.025), and low-density lipoprotein (-11.7 vs. 6.7; P = 0.0001), compared to the placebo group. None of the patients in the intervention and placebo groups reported any side effects. Conclusions: Using KF, along with a calorie-restricted diet, can reduce cardiometabolic risk factors in overweight and obese women. However, further studies are needed to elucidate the efficacy of KF as a complementary therapy in obesity.
