This report explores the potential role of neem () as a natural postmortem preservative. A 33-year-old male who died due to drowning was brought for autopsy several days after death, covered entirely in neem leaves by his family. Despite the delay, decomposition was notably less advanced than typically expected, with reduced skin slippage, bloating, and putrefactive odor. This observation suggests neem's antimicrobial and antifungal properties may help delay postmortem changes. In resource-limited or culturally specific settings, neem may offer a temporary, plant-based alternative to traditional preservation methods, warranting further scientific investigation.

The limited water solubility and environmental instability of natural pesticidal compounds impede their broader agricultural use. This study reports an amphiphile-assisted nanoprecipitation method to imbibe azadirachtin-rich neem seed extract (NSE) within a glycine carrier matrix, yielding a stable nanocomposite biopesticide. The formulation, prepared using polyoxyethylene sorbitan monooleate as a stabilizer and glycine as the matrix former, followed by lyophilization, exhibited a hydrodynamic diameter of ∼8 nm when redispersed in water.

The present research reports the synthesis of poly-[ethylene oxide]-based composite films (500 μm) containing metal nanoparticles (NPs) [Ag ( ∼ 6 nm), Cu ( ∼ 25 nm), and Fe ( ∼ 35 nm)] as the mobile phase. The novelty of the study is in the corroboration of a plausible mechanism for the generation of metal NPs through green synthesis using herbal extracts of (Tea) and (Neem). Density functional theory (DFT) is used to optimize the phytoreductants present in both biosources, wherein the reducing and/or stabilizing functional entities are primarily hydroxyl groups (-OH).

The neem tree (), native to the Indian subcontinent, has recently gained global recognition because of its extensive therapeutic qualities. It contains a high concentration of antioxidants and other valuable active substances including azadirachtin, salannin, nimbidin, nimbolinin, nimbidol, nimbin, and quercetin, which are extracted from various plant parts. It has been widely utilized in Ayurveda, Unani, and Homeopathic treatments and has gained significant attention in modern medicine.

Purpose: The loss of flower quality after harvesting is a major concern in the floriculture industry. Because cut flower solutions are quickly contaminated with microbes, causing flower damage, they must be modified to enhance and extend the life of the vase.
Methods: Eco-friendly preservative solutions were examined to investigate the efficiency of natural essential oils of eucalyptus, neem and rosemary at concentrations of 200 and 400 mg L each on the biological, physiological, and anatomical traits and vase life of solidago (Solidago canadensis) cut flower.
