Ayurveda, one of the traditional systems of medicine of India, reports that the seeds of Elaeocarpus ganitrus Linn. (Tilaceae) can be used for the treatment of hypertension. The main aim is to evaluate the antihypertensive effect of Elaeocarpus ganitrus (Rudraksha) seeds. Powdered seeds were extracted by maceration, overnight, using water, in copper (E1) and glass vessel (E2) and analyzed for antihypertensive activity in cadmium chloride (1 mg/kg intraperitoneally, for a period of 15 days) induced hypertensive male Wistar rats at three dose levels. E1 was administered at the dose of 5, 10, and 15 mg/kg and E2 at dose of 10, 20, and 30 mg/kg. All the data were analyzed using one way analysis of variance (ANOVA) followed by Dunnett's multiple comparison test. E1 and E2 did not show any toxicity at the dose of 5 g/kg in rats. It was found that 15 mg/kg of E1 and 30 mg/kg of E2 decreases the blood pressure by 30.20 mmHg and 28.96 mmHg, respectively, in hypertensive rats. Thus, it can be said that 15 mg/kg of E1 produced similar decrease in blood pressure as was observed with 30 mg/kg of E2. Copper ions in E1 might be additively affecting the reduction in blood pressure with the usage of Elaeocarpus ganitrus extracts.

Creating environmentally friendly materials like polymer matrix composites (PMCs) enhanced with natural fillers has grown in recent decades. It supports the United Nations sustainable development goals (SDGs) by reducing the reliance on non‐renewable resources, minimizing waste generation, and promoting sustainable land and water management practices. This investigation assesses the viability of employing Elaeocarpus ganitrus (rudraksha) seeds as a filler (rudraksha seed filler [RSF] in environmentally sustainable composite materials. Various loading concentrations and sizes of RSFs were incorporated by hand lay‐up into polymer epoxy resin (ER). The effect of filler on the mechanical properties of composites was observed. Thermal properties of RSF/epoxy composites were investigated using thermogravimetric analysis (TGA) and Fourier transform infrared (FTIR). The 10 wt% 100‐mesh filler had the maximum tensile strength (TS) at 42.30 MPa and flexural strength (FS) at 87.4 MPa, surpassing other filler sizes and loading concentrations. Meanwhile, the highest impact properties have been achieved with 20 wt% of RSF with 0.436 J. The results of this study highlight the significant impact of filler type and concentration on the mechanical properties of the material. These findings offer valuable insights that may be applied to various industrial contexts. Furthermore, incorporating 10% up to 30 wt% RSF in epoxy composites has brought more thermal stability than virgin epoxy. It revealed that the RSFs possess higher decomposition temperatures than the epoxy matrix. RSF has a potential sustainable reinforcement in polymer composites and holds great promise for addressing environmental challenges and aligning with several SDGs.Highlights Interest in eco‐friendly materials, like polymer composites with natural reinforcements, has been increasing in recent decades. Rudraksha sees filler is lightweight with low moisture, high carbon content, and some mineral elements. The addition of Rudraksha seed filler has enhanced the tensile, flexural, and impact properties of the composites. Rudraksha seed filler possess higher decomposition temperatures than the epoxy matrix. Rudraksha seed filler has a promising future as a sustainable friction material for automotive brake pads.
