31 Oct 2019 --- A Consumer Reports (CR) analysis of 29 herbal supplements available in the US market has found some lead levels that exceed its strict threshold, while others exceeded the US Pharmacopeia’s (USP) standards for aerobic bacteria. The CR analysis tested 16 echinacea and 13 turmeric herbal supplements in pill form in a bid to “better understand what’s inside herbal supplements” and determine their purity and potency. However, the American Herbal Products Association (AHPA) has hit back, saying the watchdog relied on “arbitrary or internal” standards for its analysis.
