The results demonstrated that these four compounds could protect neonatal rat cardiomyocytes from hypoxia-reoxygenation injury.

In the field of AD treatment, the combination of traditional Chinese medicine and modern medicine is becoming an emerging trend. Given the potenzial side effects and reduced efficacy of conventional therapeutic drugs, Chinese herbal medicines offer patients new treatment options because of their unique efficacy and low toxicity.

It has been found that the antitumor biological activity of curcumin in the body is associated with epigenetic mechanisms. That also implies that curcumin may act as a potential epigenetic modulator to influence the development of tumor diseases. The immune system plays an essential role in the development of tumorigenesis. Tumor immunotherapy is currently one of the most promising research directions in the field of tumor therapy. Curcumin has been found to have significant regulatory effects on tumor immunity and is expected to be a novel adjuvant for tumor immunity.

All parts of the plant contain the tropane alkaloids hyoscyamine, scopolamine, and atropine together with several minor alkaloids, which cause poisoning such as typical anticholinergic syndrome with neuropsychiatric effects. A review of 114 papers from various databases (Scopus, Web of Science, PubMed, and Google Scholar) revealed that poisoning incidents involving this plant have been relatively common from 2001 to 2024. The analysis indicated that all cases of poisoning from <i>D. stramonium</i> can be categorized into two main groups: accidental and misuse. Accidental poisonings are primarily linked to the contamination of other crops in the field, leading to mass poisoning of humans and animals. They can also result from misidentifying the plant as another edible species, children's curiosity, and self-medication. On the other hand, misuse is typically associated with recreational drug use, suicide attempts, criminal activities, and magico-religious practices. To prevent poisoning from this plant, it is essential to eliminate the weed from fields, yards, gardens, and other disturbed areas.

The inherent obstacles of oleanolic acid, such as low permeability, limited bioavailability, and poor water solubility, have restricted its therapeutic applicability.

This review briefly summarises the signalling pathways involved in the pharmacological activities of oleanolic acid as a monotherapy and in combination with other drugs. The review devotes a substantial portion to explaining the formulation developments, emphasising nanotechnology as a key factor in the improvement of the therapeutic potential of oleanolic acid. Several investigated novel formulations have been discussed, including liposomes, nanoemulsions, phospholipids, and polymeric nanoparticles, emerging synergistically as an efficient delivery of oleanolic acid and several other drugs.
