Because stinging nettle contains ingredients that regulate blood sugar, decrease inflammation, and increase urination, it’s used to treat diabetes, osteoarthritis, urinary tract infections, kidney stones, and muscle pain. When consumed as an extract, stinging nettle has been shown to improve blood sugar metabolism in mice (via MSN). When consumed as an herb (as opposed to the extract), stinging nettle seems to affect our metabolism and the way we burn fat positively. A recent study by the University of Maryland revealed that feeding mice the leaves from the stinging nettle plant prevented the critters from gaining weight — even while being fed a high-fat diet.

NC State Extension reports that topical creams containing stinging nettle are used for joint pain and various skin ailments, including eczema and dandruff. If you want to give stinging nettle a try, steep the dried leaves and flowers to make tea, or add the leaves, stems, and roots to soups, stews, smoothies, and stir-fries (via Healthline). Whether you try the extract, herb, or cream — remember this: The FDA doesn’t regulate the ingredients, strengths, and claims of herbal remedies or supplements, so always consult with your doctor first (via Medical News Today).
