Neuropathic pain (NP), a debilitating and chronic condition often accompanied by comorbid depression, presents significant therapeutic challenges. While conventional pharmacological treatments, though valuable, usually fall short in addressing their multifaceted nature, the pursuit of innovative solutions has led to the exploration of ayahuasca, a psychedelic brew originating from Amazonian plants, as a promising candidate. Recent investigations have unveiled its therapeutic potential in psychiatric disorders, particularly depression, characterized by notable alterations in mood-regulatory brain networks. In this narrative review, we explore ayahuasca's potential role in modulating neuropathic pain. Through the analysis of preclinical studies and functional MRI analyses, we aim to elucidate its influence on the affective-motivational component of pain perception and the complex immune modulation intrinsic to the pathophysiology of NP. Ayahuasca demonstrates the capacity to reduce activity within regions of the default mode network, closely linked with depression, thereby presenting a novel approach to addressing the interwoven complexities of chronic pain and mood disturbances. Furthermore, its potential to activate serotonin and sigma-1 receptors and modulate the immune/inflammatory response, including glial cells and the midbrain periaqueductal gray, a pivotal brain structure in the propagation and modulation of pain, provides valuable insights into its analgesic mechanisms. Despite these promising insights, we emphasize the imperative of rigorous research to establish the efficacy and safety, mechanisms of action, and long-term effects of ayahuasca therapy in the context of NP.
Postpartum Post-Traumatic Stress Disorder (PP-PTSD) is a psychological stress disorder that occurs as a result of traumatic childbirth experiences, posing significant risks to the physical and mental well-being of mothers. Although a variety of factors at different stages of the prenatal, traumatic or postnatal may lead to the development of PP-PTSD, the molecular mechanisms are still unclear. Previous studies suggest that immunity and inflammation may play an important role in its mechanism, but there is still a lack of sufficient evidence. As a result, treatment options are very limited. This review aims to provide an overview of recent research advancements in the identification, development, immune / Inflammation, and treatment approaches for PP-PTSD. Overall, PP-PTSD is influenced by multiple factors and has substantial detrimental effects; however, current treatment strategies remain incomplete. Therefore, further research efforts are warranted to ensure timely and effective interventions for a larger number of patients.
Shankhapushpi is an important Ayurvedic drug used for treating various disease conditions of nervous system. Convolvulus prostratus Forssk. is the genuine source plant for Shankhapushpi as per Ayurvedic Pharmacopoeia of India; however Clitorea ternatea L. is widely used as Shankhapushpi in southern part of India. In this study, comparative phytochemical and pharmacological evaluation has been done in two plants such as Convolvulus prostratus and Clitorea ternatea used as Shankhapushpi.
Phytochemical comparison was done by High Performance Thin Layer Chromatography (HPTLC) and High Performance Liquid Chromatography (HPLC). Detailed metabolite profiling was performed using Q-TOF-LC/MS-MS analysis. Antiamnesic activity of selected plants has been evaluated against scopolamine induced amnesia model in Wistar rats.
Phytochemical studies showed that only a few chemical constituents are common for both species. Most of the phytochemicals are different for selected species. LC/MS analysis showed presence of genipin and 7-hydroxyflavone in both species. Pharmacological study showed that both plants possess antiamnesic activity against Scopolamine induced memory loss; However C. ternatea possesses significant antiamnesic activity than that of C. prostratus.
The study provided valuable information about the selected species in terms of its phytochemical composition and pharmacological properties. The study also provided a scientific support for using both species as Shankhapushpi.
