Licorice intake linked to blood pressure issues in Japanese patients

This narrative review looked at how licorice and its active compounds affect patients using Japanese traditional Kampo medicine. The authors examined various forms of licorice including glycyrrhizin and glycyrrhetinic acid. They found a connection between taking these substances and developing high blood pressure or low potassium levels. The review did not report any serious adverse events or patient discontinuations based on the available information. Safety concerns focus on hypokalemia and hypertension as potential risks for those consuming these ingredients. The study was not a clinical trial but rather a narrative review, meaning it summarizes existing reports rather than testing a specific group of people. Readers should understand that this is a summary of past findings and does not prove a direct cause-and-effect relationship. The main reason to be careful is that individual factors like gut bacteria and overall health can change how a person reacts to licorice. This precision medicine approach highlights the need to consider formulation details and personal physiology when assessing risk. Patients using these medicines should discuss their specific situation with a healthcare provider to understand potential interactions.
