Ferula communis L. is thought to possess a wide range of therapeutic qualities. This plant's safety is critical regarding its potential uses as a medicine. Using the techniques outlined in the OECD recommendations, the present study aimed to assess the acute and subacute toxicity profiles of Ferula communis aqueous extract (FC-Ext) in mice. In the acute study, the FC-Ext was administered to adult male and female Swiss albino mice through oral and intraperitoneal routes at doses of 0–4 g/kg. The general behavioral effects, mortality rates, and latency of mortality were evaluated for a period of 14 days. For the sub-acute dose study, the FC-Ext was administered orally to adult mice at doses of 125, 250, and 500 mg/kg on a daily basis for 28 days. Body weight and selected biochemical and hematological parameters were measured, and histological examinations of the liver, kidney, and spleen were conducted to assess any signs of organ damage at the end of the treatment period. The results of the acute toxicity study demonstrated that the LD₅₀ values for the oral and intraperitoneal administration of FC-Ext were 3.6 g/kg and 2.3 g/kg, respectively. In the subacute toxicity study of FC-Ext, no significant changes in body weight were observed. However, a substantial increase in the weights of the liver, kidney, and spleen was observed in male mice. The administration of FC-Ext to mice at doses higher than 250 mg/kg resulted in a decrease in white blood cells and platelets in both sexes and a reduction in red blood cells and mean corpuscular hemoglobin concentration in males and hemoglobin in females. No changes in biochemical parameters were observed. Microscopic examination of vital organs such as the liver, kidney, and spleen revealed no significant injuries. Based on the current results, the aqueous extract of Ferula communis has low toxicity. These findings provide important information about the toxicity profile of the traditional medicine plant Ferula communis.

Pine needles are traditional herbal remedies used for centuries to treat various ailments, including rheumatism, bronchitis, burns, inflammation, and infections. This study aimed to evaluate the antioxidant, analgesic (peripheral and central), and wound-healing activities of Pinus pinaster (PPN) and Pinus halepensis (PAN) needles while identifying the bioactive compounds responsible for these effects. Phytochemical analysis revealed several phenolic compounds, including p-coumaroylquinic acid, quercetin, narcissin, and myricetin-3-O-glucoside. Both extracts showed strong antioxidant activity, with high total phenolic content (TPC: 384.84 ± 0.84 and 524.46 mg GAE/g DM for PPN and PAN, respectively) and flavonoid content (TFC: 109.44 ± 0.62 and 111.64 ± 0.62 mg QE/g DM, respectively). Peripheral analgesic activity, assessed using the acetic acid-induced writhing test, revealed that PAN (300 mg/kg) significantly reduced pain by 72.3%, while central analgesic effects, evaluated by the tail immersion test, were comparable to the reference drug for both extracts. In vivo wound-healing tests showed accelerated wound contraction and complete closure by day 21, indicating strong regenerative potential. Overall, this study demonstrates that PPN and PAN needle extracts possess significant antioxidant, analgesic, and wound-healing activities, supporting their traditional use and highlighting their potential as natural therapeutic agents for managing oxidative stress, pain, and skin injuries.

Background/Objectives: Plant-derived diuretics are attracting increasing interest due to their promising efficacy and improved safety profile compared with synthetic drugs. This study aimed to characterize the phytochemical composition of Astragalus boeticus (A. boeticus) extracts, evaluate their diuretic activity, and assess the oral safety of their main phenolic compound. Methods: Aqueous (AQE) and hydroethanolic (EtOHE) extracts were analyzed using LC–MS/MS, while in silico toxicity prediction of trans-resveratrol was performed using ProTox-II and ADMETlab 2.0. Diuretic activity was evaluated in male Wistar rats (n = 24) divided into four groups: control (distilled water, 10 mL/kg), furosemide (10 mg/kg), AQE (300 mg/kg), and EtOHE (300 mg/kg). Urine and plasma samples were collected after 15 days to determine electrolyte concentrations, creatinine level, creatinine clearance, and hepatic enzyme profile. Results: LC–MS/MS profiling identified fourteen phenolic compounds, with trans-resveratrol (270 µg/g in AQE) being the most abundant, followed by cyanidin-3-O-glucoside and gentisic acid. In silico assessments revealed no hepatotoxic, mutagenic, or neurotoxic effects of trans-resveratrol. Both extracts significantly enhanced urinary output, chloride excretion, and creatinine clearance, while maintaining stable renal and hepatic biochemical parameters, indicating potent diuretic activity without toxicity. Conclusions: A. boeticus extracts demonstrate strong diuretic potential associated with a favorable safety profile, likely linked to their phenolic composition dominated by trans-resveratrol. These findings support the use of A. boeticus as a natural and safe diuretic source. Further investigation is recommended to elucidate its pharmacological mechanisms and therapeutic relevance.
