Jilly Juice is a quack pseudomedicine in the form of a fermented drink that is falsely claimed by its proponents to be able to cure an assortment of conditions, including cancer and autism spectrum disorders, as well as regenerate missing limbs, reverse the effects of aging, and "cure" homosexuality. No studies have proven any of these claims, nor has the Food and Drug Administration (FDA) approved the recipe. The juice, composed of water, salt, and fermented cabbage or kale, is falsely claimed to expunge Candida (a yeast) and parasitic worms. Scientific evidence has shown that this treatment is not only ineffective, but is also toxic with potentially deadly adverse effects. Jilly Juice was conceived by Jillian Mai Thi Epperly, who has no medical or scientific background. She has garnered media scrutiny for her baseless claims that Jilly Juice can help treat medical conditions, and petitions and other efforts have been made to ban the product and its promotion from social media. Followers of Epperly have been dubbed members of a "poop cult", and by 2017, had formed a now-defunct Facebook group made up of over 58,000 members. In 2018, the Federal Trade Commission (FTC) warned Epperly that it is against the law to advertise a product's health benefits without proper scientific support. Jilly Juice consists solely of water, salt, and room temperature fermented cabbage or kale. According to proponents, the recipe for Jilly Juice includes two cups of water, a tablespoon of pink or sea salt, and two cups of cabbage or kale. The recipe calls for the ingredients to then be thoroughly puréed in a blender, poured into a glass jar, covered with cheesecloth, and left to ferment at room temperature for three days. Jillian Mai Thi Epperly, the creator of Jilly Juice, has claimed that salt is a "positive element" for the immune system, and that cabbage contains important probiotics and nutrients. She has recommended that individuals start consuming two cups of Jilly Juice per day, and then gradually increase consumption of it to up to 16 cups a day.
