Verified localization and pharmacognosy of herbal medicinal plants in a combined network framework.

Pharmacognosy from medicinal plants involves the scientific domain of medicinal compounding based on their medicinal properties. Accurate identification of medicinal plants is crucial, especially by examining their leaves. Choosing the wrong plant species for medicinal preparations can have adverse side effects. This study presents a Human-Centered Artificial Intelligence approach for medicinal plant identification, combining a YOLOv7-based Leaf Localizer with a leaf Class Verifier based on DenseNet through a Confidence Score Analyser algorithm. The Confidence Score Analyser ensures reliability by evaluating predicted categories against predefined thresholds, and the ensemble technique through majority voting enhances robustness. An average performance gain of 25.66% sensitivity is observed when comparing the YOLO object detection model with 77.45% precision to the YOLO integrated with the class verifier model with 97.33% precision. Consistent sensitivities are achieved through the ensemble technique, showcasing robustness across diverse scenarios. The final step incorporates automated textual and audio pharmacognosy information about the identified medicinal plant properties and their utility. Real-time applicability as a smart phone application makes this approach invaluable for medicinal plant collectors and experts.

Pharmacognostic characterization of Dicleptera chinensis by scanning electron microscopy, light microscopy, and analytical techniques.

Dicleptera chinensis J. (Acanthaceae) has been employed in traditional medicinal systems for treating various ailments. It has been used as an anti-inflammatory, wound healing, diuretic, and detoxifying agent in different regions of the world. This study determines several pharmacognostic standards, which are useful to ensure safety, efficacy, and purity of D. chinensis. Different parts of the plant were examined through a scanning electron microscope and light microscope, and cross-section images revealed several useful botanical features of the plant. The color, size, odor, shape, and surface characteristics of plant parts were also examined macroscopically. Pharmacognostic standardization parameters including ash values, loss on drying, swelling index, hemolytic index, and foaming index were determined in accordance with WHO guidelines. Heavy metal analysis was executed through atomic absorption spectrophotometer which depicted the presence of heavy metals and trace elements within the acceptable range. Qualitative phytochemical tests for alkaloids, flavonoids, saponins, glycosides, tannins, carbohydrates, lipids, protein, and so forth of plant extract were also performed, which showed the valuable amount of these phytochemicals useful for medicinal purposes. Preliminary phytochemical tests provide an indication for major phytoconstituents classes present in the plant. These quantitative and qualitative microscopic features are helpful in establishing the pharmacopeia standards of plant. Assessment of various pharmacognostic features such as morphology of various plant parts explained along with physicochemical and phytochemical analysis could be very helpful for future research. RESEARCH HIGHLIGHTS: Pharmacognostic standardization is employed as reported evidence for correct identification of D. chinensis. Structures identified by scanning electron microscopy and light microscopy serve as diagnostic features of plant. Important secondary metabolites present in the plant suggest the need for further exploration through advanced metabolomics and other analytical techniques.

[De Gustibus Non Est Disputandum : On the Epistemological Status of Taste Perception in Galen's Specific Pharmacology]. / Über Geschmack lässt sich nicht streiten? : Zum epistemologischen Status der Geschmackswahrnehmung in der speziellen Pharmakologie Galens.

This article examines the role of taste perception in Galen's research on simple drugs in relation to the acquisition of knowledge. To this end, 1.) I make it plausible through an examination of sources that the sometimes increased, more detailed and divergent indications of taste compared to his predecessors, especially Dioscorides and Sextius Niger, are based on Galen's own research, 2.) reconstruct Galen's research practice and 3.) examine the presentation of his results in linguistic and logical terms and explain the differences to traditional pharmacology. I argue that a) gustatory perception has a special significance in Galen's work that goes far beyond its traditional descriptive function and b) that, starting from the realisation that taste and drug action are interrelated, he assigns to taste qualities an indicator function for a much more fundamental principle that causes drug action and thus c) has prepared the ground for a pharmacognosy that also classifies according to taste principles, which was to reach its climax much later. With a view to a practice of gustatory testing of herbal drugs that is still practised today in pharmacy, which, like any other natural science discipline, has otherwise largely lost the sensory reference to its subject matter, the article would therefore like to provide an encouragement to study the "history of pharmaceutical-medical tasting".

A scientific pharmacognosy on Gaucher's disease: an in silico analysis.

From ancient times, studies on herbal medicine and pharmacognosy have increased gradually worldwide, due to the increased side effects, adverse drug reactions, and charge lines of modern medicines. Plants are well known for their medicinal effects and nutritional values. They contain bioactive compounds which display a wide spectrum of therapeutic effects. Gaucher's disease (GD) is a rare autosomal recessively inherited metabolic disorder caused due to the defect in Glucosylceramidase beta gene coding for the enzyme acid-ß-glucosidase in humans. We revealed the profound binding efficiency of five selected bioactive compounds from different plants against the main enzyme acid-ß-glucosidase responsible for GD through molecular docking. An in silico approach along with the ADMET profiles of phytocompounds was done using the Schrodinger software. The preventive measure of GD leads to side effects, inaccessible and unaffordable which put forth the emergence of phytocompounds which have fewer toxic effects, and one such compound is ß-D-Glucopyranose with the best docking score (-10.28 kcal/mol) and an excellent binding affinity than other ligands, which could be further analyzed for stability using molecular dynamics study and in vitro. Being a dietary supplement, these compounds could be prepared in any form of formulation as a drug.

Chrysopogon zizanioides-a review on its pharmacognosy, chemical composition and pharmacological activities.

Vetiver is a traditional plant with versatile applications in medicine, aroma, commerce, environmental-protection, and agriculture. This review was designed to compile all the latest information on phytochemistry, pharmacology, and traditional uses of C. zizanioides. All the information related to this plant was gathered from several authentic sites, using keywords like Chrysopogon zizanioides, Vetiveria zizanioides, Khus, and Khas-Khas. The included resources were journaled articles, book chapters, books, Ayurvedic Pharmacopoeias, and Ayurvedic Formulary of India, from science direct, PubMed, research gate etc. All the necessary, relevant, authentic, and updated information were tried to inculcate in the manuscript. The literature was collected via online sites like Pub med, Scopus, and Science direct as well. During compilation, it observed that many traditional utilities of vetiver got their authentication when tested using different disease-based pharmacological models taking various extracts of roots, leaves, and root oil as test samples. However, systematic studies for isolation of active constituents and establishing their mechanism of action are still required to be validated. On the other hand, the development of novel and robust techniques needed for oil extraction can further enhance the exploration of biological utilities faster. Moreover, the cultivators and harvesters must address carefully to prevent the linked drawback of soil erosion.

A novel challenge of nondestructive analysis on OGATA Koan's sealed medicine by muonic X-ray analysis.

OGATA Koan (1810-63) was a physician and the director of Tekijuku, and he contributed to Western medicine in the late Edo period. Osaka University preserves two of his medicine chests. One of the chests, which was used in his last years (the second chest) contained 22 glass bottles and 6 wooden cylinders. These bottles and cylinders contained formulated medicines; however, about half cannot be opened because of the long-term storage. It is necessary to comprehend the physical property of both the containers and their contents for investigation of this adequate preservation method; however, destructive analysis is not allowed. To analyze the medicines sealed in the glass bottles, we focused on muonic X-ray analysis, which has high transmittance. First, we certified the analytical methods using a historical medicinal specimen preserved in Osaka University. Thereafter, we applied the method on the bottles stored in the second chest. X-ray fluorescence identified the glass of those bottles to be lead potash glass. Among these bottles, we chose the bottle with the label "," which contains white powdered medication, for muonic X-ray analysis. We identified the contents of the medication in the glass to be Hg2Cl2. Through this study, we first applied muonic X-ray analysis on the medical inheritances and succeeded to detect the elements contained both in the container and in the contents of the sealed bottle. This would be a new method for nondestructive analysis of such cultural properties.

These evaluations provided referential information for correct authentication and quality standardization of the important medicinal plant material. These information will also be supportive to differentiate Datura stramonium from the closely related other species.

Micromorphology, pharmacognosy, and bio-elemental analysis of an important medicinal herb: Verbascum thapsus L.

The present study was conducted on characterization of morpho-anatomical, phytochemical, and bio-elemental analysis of root, stem, and leaf of Verbascum thapsus. Morphologically Verbascum is a biennial plant that flowers for a month and a half in mid- to late summer. Various organoleptic features of root, leaf, and stem were recorded. Anatomically the T. S of the root, stem, and leaf showed a typical dicot histological differentiation. Leaf possessed anomocytic stomata, crescent shape vascular bundles, and covered with long and stellate type trichomes while, stem contained collateral type of vascular bundles and a well-developed pith to store phytochemicals responsible for various pharmacological activities. The powder drug study through scanning electron microscopy revealed the presence of various types of tissues. Branched, tree like and stellate trichomes in root and leaf help in absorption and reduce loss of water. These anatomical features are responsible for the survival of the plant as biennial. Four macro elements (Na, K, Ca, and Mg) and seven microelements (Cr, Cu, Fe, Mn, Ni, Zn, and Cd) and their concentrations in ppm were also studied using Atomic Absorption Spectroscopy. Phytochemical screening of methanolic extract showed existence of various secondary metabolites, while mucilage and anthraquinones was not detected. The present study helps to understand the taxonomic identification of the plant based on morpho-anatomical features and throws the attention of the researchers to carry out the work for developing its various formulations, which can ultimately be beneficial for the human beings as well as animals.
