Introduction: Eurycoma longifolia Jack (EL), profoundly recognised as 'Tongkat Ali', is a medicinal herb originating from Southeast Asia. It is commonly used in traditional 'antiageing' treatments to address decreased energy, mood, libido and hormonal imbalances. While the benefits of EL have been extensively studied among the male population, less attention has been given to its effects on women. Menopause can impact the overall well-being of middle-aged women and incorporation of herbal supplements can aid them in managing the menopausal symptoms.
Methods and analysis: This 12-week randomised double-blind, placebo-controlled, parallel-group study aims to evaluate the efficacy of the standardised water extract of EL known as Physta in increasing the quality of life of perimenopausal and postmenopausal women. The study involves 150 women aged 40-55 years who score more than 61 on the Menopause-Specific Quality of Life (MENQOL) assessment. These participants will be randomised into three groups, receiving Physta at either 50 mg or 100 mg or a placebo. The outcomes measures include mood state, quality of life, fatigue, sleep quality, sexual function and pain score assessed using Profile of Mood State, MENQOL, Chalder Fatigue Scale, Pittsburgh Sleep Quality Index, Female Sexual Function Index and the Brief Pain Inventory questionnaires, respectively. The secondary outcome of the study includes full blood analysis, urine analysis, female reproductive hormone profiling, inflammatory and oxidative stress biomarkers analysis.
Ethics and dissemination: The research protocol of the study was reviewed and approved by the Research Ethics Committee of Universiti Kebangsaan Malaysia (UKM/PPI/111/8/JEP-2021-898). The findings will be disseminated to participants, healthcare professionals and researchers via conference presentations and peer-reviewed publications.
