AG Brnovich Issues Cease-And-Desist Letter to Phoenix Dispensary Over COVID-19 Tincture Advertising

Arizona Attorney General Mark Brnovich issued a cease-and-desist notice last Friday to Phoenix-based YiLo Superstore Dispensary to stop YiLo from advertising products as a treatment or cure for COVID-19.

According to information received by the Attorney General’s Office (AGO), text messages have been circulating offering for sale a “Coronav Immunization Stabilizer Tincture,” in connection with YiLo. There is currently no Food and Drug Administration-approved vaccine to immunize against, prevent, or cure COVID-19.

YiLo also maintained a webpage giving consumers instructions on how to use this “Coronav Tincture” if consumers “come down with a life threatening virus.” The webpage stated that “if you have [the coronavirus], it is suggested trying” YiLo’s product. The webpage was previously located at

Since the AGO notified YiLo of the cease and desist on Friday, the webpage has been taken down.

The letter demands that YiLo cease and desist advertising that its products could have an effect on COVID-19 without any supporting scientific evidence. It alleges that the text messages violate the Arizona Consumer Fraud Act by “fraudulently advertising at least some of its merchandise as having an effect on COVID-19 or on the immune system’s ability to resist or combat the disease” when there is insufficient scientific evidence to support that claim.
