<p><em>Hypertension is a dangerous silent killer disease because it can increase complications that can be life-threatening. Meanwhile, many people and health workers do not know about the health effects of giving doses of dark chocolate as a complementary therapy, especially in reducing high blood pressure for hypertension sufferers. This research was conducted using the scoping review method to search for literature on the effects of dark chocolate and identify effective doses, and ingredients in dark chocolate that are useful for lowering high blood pressure and side effects in research during the intervention. Article searches were carried out based on keywords with journals in English and Indonesian from 2012 to 2022 through the PubMed, Proquest, ScienceDirect, EBSCO, and Google Scholar databases which were then filtered and selected based on criteria. Based on the 7 articles obtained, 4 articles found recommended doses of dark chocolate which affected lowering blood pressure with the dose range being &lt; 30 g and &gt; 50 g. Apart from that, several ingredients can affect lowering blood pressure, namely flavonoids, and polyphenols, with several studies mentioning side effects that occur as a result of consuming dark chocolate. When administering doses, caution is needed with patients taking certain medications because they can cause side effects on health. In future research, it is hoped that we can carry out a broader review that explains the effect of dark chocolate in reducing high blood pressure, especially in monitoring the effects of giving doses of dark chocolate to sufferers who take certain medications.</em></p>
