Salvia mellifera-How Does It Alleviate Chronic Pain?

An overview of the effect of medicinal herbs on pain

This paper is typically intended to carefully collect and properly review the antinociceptive activities of medicinal plants. In this review article, by searching keywords of medicinal plants, pain, herbal medicine, antinociceptive, phytotherapy in databases of Web of Science, Scopus, Google Scholar, Springer, Wiley, Proquest, PubMed, Nature, Magiran, Emerald, SID, ISI, and some other indexing cites, or traditional books, desired articles were obtained until 2021. The title of medicinal plants was searched diligently in Persian and English. Ultimately, 270 articles were studied. The findings possibly indicated that several medicinal plants are among the most valuable plants that have antinociceptive activities. There efficiently are various antinociceptive compounds in medicinal plants. The antinociceptive activity of these specific compounds may be through their peculiar effects on the opioid system, cholinergic pathways, and stimulation of GABA receptors, with the peripheral and central antinociceptive mechanism. Antiinflammatory processes, inhibition of the synthesis, and the release of arachidonic acid, prostaglandins, phospholipase, nitric oxide, and cyclooxygenase-2 have been reported as analgesic mechanisms of some herbs. In a reasonable conclusion, our review thoughtfully provides a comprehensive summary of present data from some scientific studies on the common herbs with antinociceptive and antiinflammatory activities.

Eupatorin 3'-O-glucopyranoside, a trimethoxyflavonoid glucoside from the aerial parts of Salvia mellifera

Salvia mellifera, native to California, Baja California, and Mexico, is a medicinal herb traditionally used to relieve pain, body aches, including chronic pain. A detailed phytochemical investigation of aerial parts of S. mellifera was accomplished to find species-specific markers and to differentiate the closely related, often (un)intentionally substituted with S. apiana. A total of 22 metabolites, including flavonoids (1-14), triterpenoids (15-18), diterpenoids (19-21), and phenylpropanoid (22), were isolated and characterized thoroughly. Among the isolates, eupatorin 3'-O-glucopyranoside (1) was identified as undescribed phytochemical and detailed structure elucidation was achieved through extensive NMR and mass spectral data analysis.

Comparative analysis of five Salvia species using LC-DAD-QToF

Several Salvia species, commonly known as sage plants, are an integral part of various culinary and folklore preparations for the perceived wide range of effects from organoleptic to psychological. As a result, many of these species are an integral part of botanical drug applications, highlighting the need for accurate identification and quality control for consumer's safety. Five closely related Salvia species (S. officinalis, S. miltiorrhiza, S. divinorum, S. mellifera, and S. apiana) within a same botanical family were analyzed and differentiated using LC-QToF. Accurate mass measurement (<5 ppm) of protonated and deprotonated molecules together with resulting fragments and product ions allowed unequivocal or tentative identification of more than 180 compounds either by comparison with reference standards or literature data. The leaf part were identified based on various phenolic acids, flavonoids as well as di- and tri-terpenoids. Polyphenolics, viz., salvianolic A/B and rosmarinic acids in S. officinalis, lipophilic diterpenoids, viz., tanshinones in S. miltiorrhiza, abietatriene diterpenes and triterpenoids (ursane-/olean-type) in S. mellifera, and S. apiana were identified as characteristic, significant components. In comparison, salvinorins and divinorins representing a class of neoclerodane diterpenoids were detected only in S. divinorum. The presented methodology can successfully be applied to qualitatively assess sage-based ingredients in various finished products and formulations.

Sage Species Case Study on a Spontaneous Mediterranean Plant to Control Phytopathogenic Fungi and Bacteria

Sage species belong to the family of Labiatae/Lamiaceae and are diffused worldwide. More than 900 species of sage have been identified, and many of them are used for different purposes, i.e., culinary uses, traditional medicines and natural remedies and cosmetic applications. Another use of sage is the application of non-distilled sage extracts and essential oils to control phytopathogenic bacteria and fungi, for a sustainable, environmentally friendly agriculture. Biocidal propriety of non-distilled extracts and essential oils of sage are w documented. Antimicrobial effects of these sage extracts/essential oils depend on both sage species and bacteria and fungi species to control. In general, it is possible to choose some specific extracts/essential oils to control specific phytopathogenic bacteria or fungi. In this context, the use of nanotechnology techniques applied to essential oil from salvia could represent a future direction for improving the performance of eco-compatible and sustainable plant defence and represents a great challenge for the future.
