A comprehensive review on ethnomedicinal uses, phytochemistry, toxicology, and pharmacological activities of Dittrichia viscosa (L.) Greuter

Abstract

Dittrichia viscosa is a perennial herb that has been used for generations in traditional medicine to address a variety of diseases, including diabetes, hypertension, cancer, microbial disorders, inflammatory conditions, and wound healing. The objective of this review is to provide an overview of existing knowledge on D. viscosa with regards to its botanical description, ethnomedicinal uses, and pharmacological properties. Databases such as Scopus, Wiley-Online, PubMed, Springer, Google Scholar, and ScienceDirect were used to select relevant articles based on their title and abstract.The reviewed studies found a strong correlation between D. viscosa's traditional uses and its observed biological effects. Pharmacological research has shown that the essential oils and extracts from D. viscosa possess a variety of biological activities, such as anti-inflammatory, anticancer, antibacterial, antifungal, analgesic, and antioxidant properties. The chemical compounds found in D. viscosa include sesquiterpenes, monoterpenes, flavonoids, and phenolic acids; some of these compounds, such as tometosin and inuviscolide, have been isolated and displayed promising cytotoxic and anti-inflammatory activity.The present review suggests that the pharmacological properties of D. viscosa align well with its ethnomedicinal uses. These findings support the traditional use of D. viscosa in treating various illnesses. Additionally, toxicological examinations of D. viscosa extracts and essential oil have demonstrated the plant's safety, which supports the need for comprehensive pharmacological studies, in vivo studies, and clinical trials to evaluate the best doses for optimal medicinal effects. This work underscores the medicinal value of D. viscosa and its potential in developing new pharmacological agents to address major health challenges like antibiotic resistance and cancers.
