The NYBG researchers are already setting their sights on other popular plant-based supplements. Supplements currently under study include saw palmetto (from Serenoa repens, often used for prostate troubles); ginseng (in the Panax genus, marketed for improved mental function); devil's claw (Harpagophytum procumbens, sometimes indicated for arthritis or other ailments); and even garlic (Allium sativum, often taken for cardiovascular health, which they suspect might sometimes be adulterated with elephant garlic—A. ampeloprasum—a similar species, but one that has not been subject to the same testing as common garlic itself).
Many of these other supplements are not likely to carry the possibility of toxicity the same way that black cohosh does. But, as Little maintains, "you should know what you're buying."
