<div><p>The FDA advisory about licorice is a few years old, but the memes about it will live on forever. “FDA issues warning about black licorice for halloween,â€ one headline read. And then below that, in a <span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://ifunny.co/picture/kLIb7Xyy6&quot;,{&quot;metric25&quot;:1}]]" href="https://ifunny.co/picture/kLIb7Xyy6" rel="noopener noreferrer" target="_blank">screenshot taken for posterity</a></span>, somebody comments that the warning must have been “It tastes like shit.â€<br></br></p><p>The warning was actually that candy made with licorice root can mess with your blood pressure. It’s no longer up on the FDA’s website (having been issued in 2017) but the <span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://web.archive.org/web/20190601230554/https://www.fda.gov/consumers/consumer-updates/black-licorice-trick-or-treat&quot;,{&quot;metric25&quot;:1}]]" href="https://web.archive.org/web/20190601230554/https://www.fda.gov/consumers/consumer-updates/black-licorice-trick-or-treat" rel="noopener noreferrer" target="_blank">archived copy</a></span> states: </p><blockquote data-type="BlockQuote"><p>If you’re 40 or older, eating 2 ounces of black licorice a day for at least two weeks could land you in the hospital with an irregular heart rhythm or arrhythmia.</p><p>FDA experts say black licorice contains the compound glycyrrhizin, which is the sweetening compound derived from licorice root. Glycyrrhizin can cause potassium levels in the body to fall. When that happens, some people experience abnormal heart rhythms, as well as high blood pressure, edema (swelling), lethargy, and congestive heart failure.</p><p>FDA’s Linda Katz, M.D., says last year the agency received a report of a black licorice aficionado who had a problem after eating the candy. And several medical journals have linked black licorice to health problems in people over 40, some of whom had a history of heart disease and/or high blood pressure.</p><p>Katz says potassium levels are usually restored with no permanent health problems when consumption of black licorice stops.</p></blockquote><p>Yes, black licorice tastes terrible to many people. But there is a balance in the universe. Some weirdos happen to <em>love</em> the stuff, and as a result there is always somebody around, often a grandpa or an uncle, who is happy to eat the black jelly beans you don’t want.</p><p>Full disclosure, I am one of those weirdos. I always hated black licorice, until one day I didn’t. If I buy an eight-ounce bag of Trader Joe’s soft black licorice, I have to pace myself—just a few pieces a day—the way some people do with chocolate. Invite me to your Halloween parties. I’ll take your licorice and you can have my Hershey bars.</p><p>(For the <span><a data-ga="[[&quot;Embedded Url&quot;,&quot;External link&quot;,&quot;https://twitter.com/Frank_E_Sr/status/1058089876279750663&quot;,{&quot;metric25&quot;:1}]]" href="https://twitter.com/Frank_E_Sr/status/1058089876279750663" rel="noopener noreferrer" target="_blank">FDA follower on Twitter</a></span> who wrote that “licorice is a flavor, not a color,â€ I feel obliged to note that the licorice plant has lent its name to a number of chewy American candies.
