The available studies linked here do not investigate yarrow or its effects on blood circulation in any way. One study examined the accuracy of a hormone measurement technique for dihydrotestosterone in human serum, and the other explored growth hormone responses to blood flow restriction exercise in young versus older men. Neither study is relevant to yarrow or circulatory outcomes, so no evidence-based summary connecting yarrow to blood circulation can be drawn from this research. Anyone seeking information on yarrow and circulation would need to consult studies that directly examine yarrow's phytochemical constituents or clinical effects on vascular or circulatory endpoints.
