Evaluation of the Antioxidant and Healing Properties of the Hydroethanolic Extract of Kalanchoe pinnata (Lam) Pers of the Togolese Flora

Natural herbal remedies have always been important in the management of skin disorders and the treatment of skin infections due to limited access to pharmaceuticals and the affordable cost of herbal products. K. Pinnata is a plant used as a medicinal herb by almost all traditional medicines in tropical Africa. The aim of the present work is to evaluate the antioxidant and healing properties of K. pinnata (Lam) pers extract from Togolese flora. The hydroethanol extract of K. pinnata (Lam) pers was subjected to in vitro antioxidant activity screening models, such as molybdate reduction, iron reduction assay (FRAP) and DPPH radical scavenging assay. A 1.5 cm diameter excision wound model was also used to assess the plant's healing activity. Wistar rats were treated after excision by topical application of vaseline, vaseline supplemented with 3% (EHKP 3%) and 10% (EHKP 10%) hydroethanol extract of K. pinnata (Lam) pers leaves, sulfadiazine (reference), or no treatment (negative control). Total antioxidant activity by the molybdate reduction method was 0.12 ± 0.01 µg EAA/mg EL, while the iron reduction assay (FRAP) showed an antioxidant capacity of 4.21 ± 0.04 mol Eq FeS04/ g extract and 10.17 ± 0.03 mol Eq FeS04/ g extract respectively for extract concentrations of 100 µg/ml and 200 µg/ml. In addition, the extract showed a dose-dependent ability to trap the DPPH radical. Results showed a significant reduction in wound surface area in animals treated with 10% EHKP. The hydroxyproline assay showed a significant difference in collagen production in animals treated with 10% EHKP, compared with the control group (P < 0.001) and the vaseline group (P < 0.01) on the last day. Histological analysis showed rapid re-epithelialization in animals treated with the extracts. Keywords: K. pinnata, Antioxidant activity, Healing activity, Hydroxyproline

Development and Assessment of Helicteres isora Extract Loaded Phospholipid Complex for Anti-Nociceptive Activity

Its primary objective is to assess the efficacy of a phospholipid complex formulation containing an extract of Helicteres isora in reducing inflammation, to determine its progress and evaluation. An Indian Screw Tree, also known as Helicteres isora, is an extremely healing plant. In addition to improving solubility and stability, the phospholipid complex formulation also increases bioavailability and efficacy. This formulation was created by combining Helicteres isora extract with phospholipids using a technique known as phospholipid complexation. Several parameters were evaluated to evaluate the formulation, including particle size, zeta potential, encapsulation efficiency, and drug release profile. Using both in vitro and in vivo models, the anti-inflammatory properties of a phospholipid complex formulation of Helicteres isora were assessed. The experiments were conducted using a rat model of carrageenan-induced paw edema. In this work, phospholipid complex formulations were shown to have improved physicochemical properties, including smaller particle sizes and higher encapsulation rates. According to the results of the in vivo evaluation, phospholipid complex formulations significantly reduced paw edema compared with plain extracts, indicating improved anti-inflammatory activity. The bioavailability, anti-inflammatory activity, and bioavailability of Helicteres isora extract are enhanced by the phospholipid complex formulation.

VOLKSMED Database: A Source for Forgotten Wound Healing Plants in Austrian Folk Medicine

AbstractThe global increase in the incidence of wounds is concerning and fuels the search for new treatment options. The use of traditional medicinal plants in wound healing represents an appreciated available therapeutic possibility. This work introduces the VOLKSMED database, which contains plants and other materials used in Austrian folk medicine, either as monographs or mixtures. This work focuses on the monographs of the database. Concerning wound healing, Hypericum sp., Arnica montana, Calendula officinalis, Plantago sp., and Malva sp. are the most commonly used plants. The focus of this paper is set on selected lesser-known plants (Abies alba, Anthyllis vulneraria, Brassica sp., Gentiana sp., Larix decidua, Picea abies, Sambucus sp., Sanicula europaea) and their status quo in literature concerning wound healing. A systematic search using the databases SciFinder, SCOPUS, and PubMed yielded substantial evidence for the wound healing potential of Brassica sp., Gentiana sp., the Pinaceae A. abies, L. decidua, and P. abies, as well as Sambucus nigra. In vivo and clinical studies substantiate their use in Austrian folk medicine. According to the literature, especially A. vulneraria, Sambucus racemosa, and S. europaea would be worth investigating in-depth since data concerning their wound healing effects – even though scarce – are convincing. In conclusion, the VOLKSMED database contains promising opportunities for further treatment options in the field of wound healing. Future research should consider the listed plants to support their traditional use in Austrian folk medicine and possibly promote the implementation of old knowledge in modern medicine.

Psychoactive and other ceremonial plants from a 2,000-year-old Maya ritual deposit at Yaxnohcah, Mexico.

For millennia, healing and psychoactive plants have been part of the medicinal and ceremonial fabric of elaborate rituals and everyday religious practices throughout Mesoamerica. Despite the essential nature of these ritual practices to the societal framework of past cultures, a clear understanding of the ceremonial life of the ancient Maya remains stubbornly elusive. Here we record the discovery of a special ritual deposit, likely wrapped in a bundle, located beneath the end field of a Late Preclassic ballcourt in the Helena complex of the Maya city of Yaxnohcah. This discovery was made possible by the application of environmental DNA technology. Plants identified through this analytical process included Ipomoea corymbosa (xtabentun in Mayan), Capsicum sp. (chili pepper or ic in Mayan), Hampea trilobata (jool), and Oxandra lanceolata (chilcahuite). All four plants have recognized medicinal properties. Two of the plants, jool and chilcahuite, are involved in artifact manufacture that have ceremonial connections while chili peppers and xtabentun have been associated with divination rituals. Xtabentun (known to the Aztecs as ololiuhqui) produces highly efficacious hallucinogenic compounds and is reported here from Maya archaeological contexts for the first time.

Signal transduction in wound healing: The effects of plant-derived biologically active substances

Wounds are among the most common skin diseases. They are formed after tissue injury and result in severe damage to the epidermis. The application of plants for wound healing is not only a cheap and accessible way of treatment, but also provides a reliable natural resource of medicinal substances with fewer side effects. Biologically active substances such as alkaloids, essential oils, flavonoids, tannins and phenolic compounds demonstrate a wide spectrum of action: wound healing, anti-inflammatory, antibacterial and antioxidant effects. This review article examines the chemical composition of three plants - Calendula officinalis, Marrubium vulgare, Vitis vinifera and the signal transduction in skin wound healing. Studies have shown that they have a strong antioxidant effect, hemostatic activity, powerful vasoconstrictor effect, pro-angiogenic and cell-protective effects. Because of the mentioned benefits of these plants, more scientific research and well-designed clinical trials are needed to establish their wider use in wound treating medicaments.

Saúde, cultura e raízes ancestrais: fitoterapia indígena como prática de cuidado histórico pela biografia das plantas

This text brings a dialogue between a Pajé, from the Potiguara ethnic group, and an anthropologist about health and ancestral culture based on indigenous phytotherapy. It is an experience report of the course taken with the Pajé Amanacy, in the municipality of Baía da Traição, in Paraíba, together with a biographical account of the Pajé, whose history with the pajelança and the healing plants are recalled and brought to the gift. The dialogue between the experiences of the two authors traces a path in which the biography of plants governs the openings of the medical encounter between biomedicine and ethnomedicine, in official public health policies and how phytotherapy has been implemented in the Unified Health System (SUS). By following the history of the Potiguara, in Baía da Traição; the transformation of an indigenous woman into a Pajé, healer and teacher; An anthropologist's experience with the culture of the land, we reflect on the biographical portrait that plants present to us and how ethnomedicine mobilizes ancestral roots to the center of health policies.

Unveiling the Therapeutic Potential and Conservation Strategies for Rare and Endangered Medicinal Plants in Traditional Chinese Medicine: A Comprehensive Review.

Incorporating rare and threatened healing plants from Traditional Chinese Medicine (TCM) into modern medicine is a hopeful way to expand treatment choices and encourage the long-term use of plant resources. These plants have been used in Traditional Chinese Medicine for a long time. They have powerful healing properties, including the ability to reduce inflammation and fight cancer. They also protect nerves and the heart. A thorough study of all the scientific studies, clinical trials, ethnobotanical surveys, and conservation reports that were found were all looked at in relation to rare and threatened medical plants used in TCM. We looked through databases like PubMed, Scopus, and Web of Science for relevant pieces. Studies published in peer-reviewed journals, reports from reputable conservation organisations, and written down traditional knowledge were all considered to be relevant. Key results show that plants like Dendrobium, Panax notoginseng, Taxus chinensis, and Cistanche deserticola can be used as medicines and that there are good ways to protect them. Some of the conservation methods that have been named are agroforestry, community-based management, current breeding techniques, and sustainable gathering. Collaboration in research, clinical trials, personalised medicine, regulatory harmonisation, and public education programs are all part of the integration with modern medicine. These programs try to solve problems like scientific proof, protection, and cultural integration. When rare and threatened medical plants from Traditional Chinese Medicine (TCM) are used in modern medicine, it can improve health and help protect wildlife. Using both old information and new science discoveries together can lead to new treatments and long-term uses for these plant materials. Large-scale clinical studies, new ways of growing plants, and looking into how TCM herbs and regular drugs can work together should be the main topics of future study. For global healthcare to improve and for these important plant resources to be used in the long term, academics, healthcare workers, lawmakers, and local communities must work together.

Short Communication: Ethnobotanical survey of medicinal plants for wound healing in Dir Upper District, Pakistan

Abstract. Jawadullah, Akhtar N. 2023. Short Communication: Ethnobotanical survey of medicinal plants for wound-healing in Dir Upper District, Pakistan. Asian J Ethnobiol 6: 145-152. Medicinal plants have been used since ancient time by the communities as an alternative to the synthetic medicine, which have adverse side effects and is not available to every individual. This study reports medicinal plants used for wound-healing by the local peoples in Dir Upper District, northern area of Pakistan. A semi-structured questionnaire was used to collect ethnomedicinal data by interviewing 50 informants of different ages (25 to 90 years old). Plant samples were collected as herbarium to be identified in the laboratory. The result shows a total of 20 plant species, each belonging to different families, were used for wound-healing. The majority of growth forms of such plants were herbs (35%) and trees (35%), followed by shrubs (25%) and climbers (5%). The plant parts used for healing were leaves of the plant (45%), followed by plant bark (10%), whole plant (10%), plant roots (10%), fruit peel (5%), gum (5%), bulb (5%), rhizome (5%) and latex (5%). Furthermore, external applications were more common than oral consumption to promote wound-healing. Berberis lycium Royle, Curcuma longa L. and Punica protopunica Balf.fil. were the most cited species used to heal wounds. This study revealed that there is an array of plant biodiversity among Pakistanis for the purpose of wound-healing. This is a result of the socioeconomic status and limited access to modern health services and their preference for folk medicine. Further studies should be planned to create an online database for a collection of therapeutic medicinal plants and their traditional healing potentials.

An Overview of the Benefits of Indian Spices for High Blood Pressure

The utilization of herbs, spices, and other plant components has a rich historical background in Indian medicine. In ancient and medieval economies, spices were among the most demanded resources. Although herbalists and alternative medicine practitioners have relied on plants for health and healing for decades, it is only in the last few decades that scientists have begun to investigate the medicinal properties of ordinary herbs and spices. Spices’ anti-hypertensive, anti-hypercholesterolemia, anti-diabetic, and anti-inflammatory characteristics are of utmost relevance in the modern world because of the prevalence of illnesses like diabetes, cardiovascular disease, arthritis, and cancer. Throughout the Middle Ages, people employed herbs and spices for cooking, food preservation, and even medicine. In developing nations like India, where poverty and malnutrition are widespread, a better understanding of plant-derived compounds and spices’ antioxidants and therapeutic effects could lower healthcare expenses. It has been postulated that food significantly impacts the onset of various human diseases, including cardiovascular disease. This manuscript looks at the research on how certain spices, such as garlic, ginger, cardamom, and cinnamon, can affect health problems like hypertension.

Enchantresses and Enchanters Through the Personalizing of “Magical Agents”: a historical, ethnographic, sociological and anthropological radiography

The personalized interdisciplinary approach to the enchantresses and enchanters as “magical agents” is intended to highlight the imagological aspects of their lives and work. Multiple stereotypes have become entrenched in society towards enchantresses and enchanters, many of them more related to people’s imaginations than to concrete historical realities. In Romania’s past, the number of enchantresses and enchanters in each locality was quite high, a fact explained by the lack of professional doctors. This gap in health care based on scientific medicine was filled by the work of “magical agents” – enchantresses and enchanters – who offered the sick both remedies of magical medicine and folk treatments, especially based on healing plants. The craft to charm was viewed with mixed appreciation, being both criticized for manipulating naive people and accepted by simple country folk for whom it had become an indispensable part of their existentialist tradition. Contrary to general perceptions, the women who were bewitched were not exclusively old women, but also young and middle-aged women. Another relevant aspect is that in the case of the Basarabian village of Cornova, in 1931, the number of charmers was quite significant, being rather an exception in the whole Romanian area.
