Background/Objectives: Essential oils are increasingly recognized for their therapeutic potential, yet Ammoides verticillata essential oil (AVEO) remains relatively unexplored, particularly for its anti-inflammatory and analgesic properties. This study aimed to profile AVEO’s chemical composition and evaluate its antioxidant, anti-inflammatory, and analgesic effects, with a focus on its novel pharmacological actions. Methods: The chemical composition of AVEO was determined using GC-MS analysis, and antioxidant capacity was assessed through in vitro assays. Furthermore, the anti-inflammatory potential was investigated using a carrageenan-induced paw edema model in rats, complemented by the inhibition assays of cyclooxygenase (COX) enzymes. The analgesic effects were evaluated through acetic acid-induced writhing and tail immersion tests. Additionally, a computational study was performed to explore the binding affinity of AVEO’s major constituents to COX-2. Results: GC-MS analysis revealed a rich monoterpene profile dominated by carvacrol (32.51%). It was found that AVEO exhibited significant antioxidant activity. Similarly, in vivo, AVEO showed significant anti-inflammatory effects, achieving a percentage inhibition of 52.23% at 200 mg/kg, comparable to diclofenac, along with potent COX-2 inhibition observed (IC50 = 1.51 ± 0.20, SI = 5.56). Moreover, analgesic tests demonstrated dose-dependent pain relief, in which the dose of 200 mg/kg significantly prolonged tail latency to 14.00 ± 1.45 s and markedly reduced abdominal constriction to 21.17 ± 1.62. Computational analysis further corroborated the high binding affinity of carvacrol and thymol with COX-2 (−7.381 and −6.939 Kcal/mol, respectively). Conclusions: These findings underscore AVEO’s potential as a promising therapeutic agent for managing inflammation and pain.

Astragalus species have long been recognized for their pharmacological relevance, yet the antidiabetic properties of Astragalus cruciatus Link (Ac) remain poorly explored. This study aimed to investigate the antidiabetic potential of A. cruciatus Link and to elucidate possible underlying mechanisms. The ethanolic extract of Ac (AcEE) was prepared and analyzed for phenolic and flavonoid content. Antioxidant activity was assessed through a series of in vitro assays. The in vitro inhibition of α-amylase and α-glucosidase was assessed, followed by molecular docking to probe ligand-enzyme interactions. LC-ESI-MS analysis revealed a polyphenol-rich profile, with rutin (953.54 µg/g extract) and quinic acid (797.18 µg/g of extract) identified as main compounds. The AcEE showed significant inhibitory activity against both α-amylase and α-glucosidase (IC₅₀ = 239.30 ± 7.40 and 192.60 ± 15.51 μg/mL, respectively). Moreover, low cytotoxic effects were observed in hepatic cell lines. Computational analysis revealed stable interactions between rutin and both enzymes (−12.935 and −8.073 Kcal/mol, respectively). Network pharmacology revealed that AcEE may modulate key targets, including IL-6, TNF-α, IL-1β, Akt-1, STAT3, EGFR, and INSR as well as pathways related to insulin resistance, AGE-RAGE, and inflammation. These findings suggest that AcEE exerts significant antidiabetic effects through multitarget modulation, highlighting its potential as a natural therapeutic agent for T2DM.
