Juniper berries are commonly used in foods and drinks. They come from the juniper tree and can be used whole or ground. Juniper oil, distilled from the tree's leaves and wood, is used in cosmetics. Despite their name, juniper berries are not true berries but a type of cone. They are edible and popular in cooking and alcohol distillation. Historically, juniper has been used for health purposes like reducing inflammation and as a diuretic. However, juniper should not replace medications for treating illnesses and could worsen some health conditions. Always consult your doctor before trying new supplements, including juniper. Juniper might increase urination, which can help with urinary tract infections but is not a substitute for antibiotics. It may aid digestion and has shown anti-inflammatory effects in animal studies, though not in humans. Juniper oil has antimicrobial properties but can irritate the skin and should not be used on wounds. High doses or long-term use of juniper can irritate the digestive system or kidneys. Some researchers advise against juniper supplements for people with diabetes as it might worsen symptoms. Pregnant women or those trying to conceive should also avoid juniper. More research is needed on juniper as a health supplement, but it has other uses like flavoring gin, seasoning meats, and in cosmetics.
