Herbalists' Views on the Top-Selling Herbs (Part 8): Milk Thistle & Black Cohosh

Herbs #22 and 23 on the top-selling herbs list for 2023 were milk thistle and black cohosh. Today we continue our series on commercially popular herbs, and share our views as herbalists on the actions, benefits, and applications of these. Milk thistle is widely known as an excellent herb for the liver, and this is a case where the common wisdom is correct. It’s one of the safest herbs out there, and fortunately, it is also widely available and inexpensive. Hepatoprotective and even able to regenerate damaged liver tissue, it is at the same time a very gentle and benign plant. But don’t try to make tea with it! Black cohosh’s reputation is as a remedy for PMS and menopausal symptoms, and often this is attributed to phytoestrogenic activity or constituents. The reality is murky – and has remained so despite decades of argument and investigation on both sides of the claim. Regardless, black cohosh can often help. We find it best to view the herb through the lens of its action as a relaxant. If PMS or menopause are showing up with lots of tension, it’s worth a try and most likely to help. But we can also apply that action much more broadly, for injuries, spasms, and (certain kinds of) headaches. 22.
