Juniper berries (Juniperus communis) are a fragrant spice used for centuries in food and herbal preparations. Their volatile oils and flavonoids contribute to the herb's properties.
People take juniper berry extracts or teas to encourage mild diuretic action and ease digestion. Chefs also add its distinct flavor to recipes. A typical approach is 1 to 2 cups of tea, steeped from crushed berries, between meals. Liquid extracts diluted in water are an alternative. Most users keep intake short-term.
High doses or extended use can irritate the kidneys. Do not use juniper if you have kidney disease, high blood pressure, or take diuretics or blood pressure medications. It may alter blood sugar levels.
