“…There is a rise in the use of herbal medicines across countries, which can also be referred to with terms including alternative medicines, botanical products, complimentary medicines, natural products and traditional medicines, with an appreciable proportion of the world’s population now using herbal medicines to treat some of their diseases ( Byard et al, 2017 ; Alsayari et al, 2018 ; Eddouks et al, 2020 ; Geck et al, 2020 ; Market Data Forecast, 2021 ). Overall, it is expected that the herbal medicine market will grow at an annual compounded growth rate of over 7.2% between 2021 and 2026 due to their lower costs, accessibility, and belief that herbal medicines can promote healthier life-styles, treat diseases such as the metabolic syndrome and gastrointestinal problems, and typically have less side-effects than prescribed medicines, which can be a concern with the toxicity of some prescribed medicines ( Calitz et al, 2015 ; Nuryunarsih, 2016 ; Alsayari et al, 2018 ; Bhat et al, 2019 ; Ekar and Kreft, 2019 ; Eddouks et al, 2020 ; Holleran et al, 2020 ; Market Data Forecast, 2021 ). This is despite concerns with the evidence base of some herbal medicines ( Geck et al, 2020 ; Holleran et al, 2020 ; Popattia et al, 2021 ), as well as potentially adverse effects including increased liver and kidney toxicity exacerbated by some herbal medicines containing heavy metals and naturally occurring organic toxins ( Calitz et al, 2015 ; Brown, 2017 ; Byard et al, 2017 ; Kum et al, 2021 ).…”
