Prescription drug and HDS exposure data in the past 30 days were analyzed, and 2020 US Census data were used for population estimates. Data were analyzed July 1, 2023, to February 1, 2024.<\/jats:p><\/jats:sec>Exposures<\/jats:title>Adult NHANES participants enrolled between January 2017 and March 2020.<\/jats:p><\/jats:sec>Main Outcomes and Measures<\/jats:title>Baseline weighted characteristics of HDS users and users of 6 potentially hepatotoxic botanical products were compared with non\u2013HDS users. Multivariable analysis was undertaken to identify factors associated with HDS use or at-risk botanical use.<\/jats:p><\/jats:sec>Results<\/jats:title>Among 9685 adults enrolled in this NHANES cohort, the mean (SE) age was 47.5 (0.5) years, and 51.8% (95% CI, 50.2%-53.4%) were female. The overall prevalence of HDS product use was 57.6% (95% CI, 55.9%-59.4%), while the prevalence of using the 6 botanicals of interest was 4.7% (95% CI, 3.9%-5.7%). Turmeric-containing botanicals were most commonly used (n\u2009=\u2009236), followed by products containing green tea (n\u2009=\u200992), ashwagandha (n\u2009=\u200928), Garcinia cambogia<\/jats:italic> (n\u2009=\u200920), red yeast rice (n\u2009=\u200920), and black cohosh (n\u2009=\u200919). Consumers of these 6 botanicals were significantly older (adjusted odds ratio [AOR], 2.36 [95% CI, 1.06-5.25]; P<\/jats:italic>\u2009=\u2009.04 for 40-59 years of age and AOR, 3.96 [95% CI, 1.93-8.11]; P<\/jats:italic>\u2009=\u2009.001 for \u226560 years of age), had a higher educational level (AOR, 4.78 [95% CI, 2.62-8.75]; P<\/jats:italic>\u2009&amp;lt;\u2009.001), and were more likely to have arthritis (AOR, 2.27 [95% CI, 1.62-3.29]; P<\/jats:italic>\u2009&amp;lt;\u2009.001) compared with non\u2013HDS users.

The most common reason for consuming turmeric and green tea was to improve or maintain health.<\/jats:p><\/jats:sec>Conclusions and Relevance<\/jats:title>In this survey study, an estimated 15.6 million US adults consumed at least 1 botanical product with liver liability within the past 30 days, comparable with the number of people who consumed nonsteroidal anti-inflammatory drugs and a commonly prescribed hypolipidemic drug. Given a lack of regulatory oversight on the manufacturing and testing of botanical products, clinicians should be aware of possible adverse events from consumption of these largely unregulated
