The presence of mast cells (MCs) is prominent in allergies, consequently stimulating the creation of therapies specifically focused on treating mast cell-related conditions. Ephedra herb (Mao) demonstrates strong anti-allergic action, but its ephedrine alkaloids (EAs) content requires careful consideration of potential hazardous effects in clinical use. Our previous investigation showed that Mao hampers the potent mast cell degranulation provoked by allergens interacting with high-affinity immunoglobulin E (IgE) receptors (FcRI), in which a pathway not requiring allergen interaction was proposed. Our investigation focused on gaining a more comprehensive view of Mao's possible ability to alter FcRI internalization by comparing two strains with differing extracellular antigen concentrations. Cellular responses, including the internalization of FcRI, were analyzed in bone marrow-derived mast cells (BMMCs) after they were administered Mao extracts. A passive cutaneous anaphylaxis (PCA) mouse model served to assess physiological events. Diverse inflammatory mediators are produced through the action of BMMCs. The potent chemokine CCL2, found among these, is thought to be regulated in a manner distinct from other pro-inflammatory mediators. Despite impeding robust degranulation in BMMCs through FcRI internalization, Mao demonstrably increased CCL2 expression. Undeniably, this response was distinct from any influence stemming from the EA community. In the PCA reaction, allergen stimulation-induced local mast cell activation was decreased by Mao treatment, hence supporting the conclusion that Mao effectively attenuates the rapid activation of mast cells and stimulates CCL2 release. These observations, taken together, offer further understanding of the Mao-induced silent FcRI internalization mechanism in mast cells, and the complex and diverse secretory responses within these cells. Studies have reported that Ponicidin (PON), a diterpenoid isolated from the Chinese medicinal herb Rubescens, is a cytotoxic drug used to treat different types of human cancers therapeutically. According to the available statistics, malignant melanoma's incidence is increasing annually, and the malignancy is exceptionally high. This necessitates early treatment intervention. We found that PON exhibits an inhibitory effect on melanoma growth, as shown in laboratory and animal experiments. The Cell Counting Kit-8 (CCK-8) assay, coupled with crystal violet staining and the terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay, were employed to evaluate cell proliferation and apoptosis, respectively. Western blotting was utilized to assess the expression of apoptotic markers and related signaling pathway proteins. The final step involved the preparation of a mouse model carrying a tumor. The viability of B16F0 and B16F10 melanoma cells was drastically decreased by the application of PON at 10 and 20 mol/L concentrations. PON's influence significantly augments the expression of pro-apoptotic proteins, consisting of cleaved-poly(ADP-ribose)polymerase (PARP) (cl.PARP), Bak, and Bim proteins, and concurrently diminishes the expression of the anti-apoptotic protein Mcl-1 and the nuclear transcription factor nuclear factor-κB (NF-κB) in melanoma cells. In conclusion, PON actively hinders the expansion of mouse xenografts in the live animal model. PON's induction of melanoma cell apoptosis is likely mediated by the suppression of the NF-κB signaling pathway, although the precise mechanism requires further investigation. Collectively, PON holds promise as a potential melanoma treatment. Adverse experiences during early life have a profound and lasting effect on the central nervous system (CNS), rather than just a temporary one; therefore, proactive measures to lessen the effects are needed. In the recent study of the functional dialogue between the central nervous system and gut microbiota, termed the brain-gut-micro
