Brief summary

In this randomised, double-blind, placebo-controlled study, 140 women aged 42 to 62 years experiencing menopausal symptoms will be randomly assigned to receive 2 grams daily of a proprietary preparation of pure Khaya Senegalensis Dry Stem Bark (Khapregesic) or a placebo for 28 days. Changes in menopausal symptoms, sleep, and fatigue will be assessed before, during, and after the intake of the investigational product. It is hypothesised that compared to the placebo, Khaya Senegalensis will be associated with greater improvements in menopausal symptoms, sleep and fatigue.

Interventions

Khaya Senegalensis Dry Stem Bark (Khapregesic) (2 tablets taken orally, two times daily, with or without food, delivering 2000 mg a day for 28 days). Adherence to tablet intake will be measured by a daily record of tablet intake using a daily questionnaire and a tablet count by the participants at the end of the study.
