|discussion=<p>American plants here included in <i>Persicaria glabra</i> often have been treated as distinct and called <i>P. densiflora</i>. The morphological differences between them and Asian and Pacific <i>P. glabra</i> are minor. Regional tendencies exist but do not appear sufficient to warrant separation of the species (K. L. Wilson 1990b).</p><!--
--><p>An infusion made from pounded whole plants was used by the Hawaiians as a blood medicine (D. E. Moerman 1998).</p>
