What is in Shou Wu Pian?

Each row as the label prints it, per serving of 3 tablets. The capsule beside an amount places it among every product in the NIH database that lists the same ingredient: the bar is the middle half of their amounts, the line in it the median, the whiskers the 10th and 90th percentiles; the green tick is the FDA Daily Value and the red dashed tick the adult upper limit (IOM).

Is that a lot?

Every amount on this label with a position sits within the middle 80% of the products that list the same ingredient; 1 ingredient sits inside a blend, so their amounts cannot be compared.

The NIH database records 3 servings a day from the label's directions; its % Daily Values are for adults and children 4 or more years of age. The directions as printed are further down this page.
