Daidzein in traditional Chinese medicine: A deep dive into its Ethnomedicinal and therapeutic applications

Introduction: Daidzein, a secondary metabolite found in Soybean (Glycine max L.) and Pueraria lobata (Willd.), plays a pivotal role in various therapeutic applications, including its potential as an anticancer agent, particularly in estrogen-dependent breast cancer, along with anti-allergic, anti-inflammatory, cardiovascular, antidiabetic, antioxidative, and neurogenerative effects. Daidzein's ability to traverse the blood-brain barrier enhances cognition, reduces aggression, and promotes locomotor activity. Its structural resemblance to estrogens positions it as a potential remedy for menopausal osteoporosis. Methodology: The methodology for the comprehensive review on Daidzein entailed a literature search utilising keywords such as "Daidzein" and various therapeutic activities, including “Antioxidant,” “Anti-inflammatory,” “Anticancer,” “Antiviral,” “Antiobesity,” “Antidiabetic,” “Nephrotoxicity,” “Cardiovascular,” “Neuroprotective,” “Osteoporosis,” “Menopausal Symptoms,” “Aging,” “Cognitive Activities”. Academic databases such as PubMed, Google Scholar, Scopus, and Web of Science were employed for the search, considering articles published within the last 20 years to capture recent research while encompassing significant historical studies. Results: The results provide insights into the diverse effects of daidzein across various health domains, including its antioxidant, anti-inflammatory, anticancer, antiviral, antiobesity, antidiabetic, nephrotoxicity, cardiovascular, neuroprotective, osteoporosis, menopausal symptoms, ageing, and cognitive activities. Discussion:: The discussion section critically analyses the collective evidence gathered from the studies. It explores the mechanisms underlying daidzein's therapeutic effects and discusses the implications of these findings for both Traditional Chinese Medicine and modern healthcare practices. However, challenges related to its low bioavailability and toxicity necessitate further research, providing a foundation for future studies on daidzein's potential applications.
