GUT HEALTH

Juniper

Juniperus communis

also known as juniper berry

Moderate (traditional use)
Juniper — Köhler 1887 botanical illustration

An evergreen shrub whose blue-black berries flavor gin and have a long traditional use as a urinary tract herb. Juniper works as a mild diuretic and antiseptic — but it can irritate the kidneys with extended use, so short courses only.

  • Mild diuretic action
  • Traditional antiseptic for urinary tract support
  • Carminative — eases gas and bloating
  • Topical use for minor muscle and joint discomfort
  • Distinctive piney flavor used widely in cooking and beverages
Can irritate the kidneys — limit continuous use to 4 to 6 weeks
Avoid with kidney disease
Avoid during pregnancy — can stimulate the uterus and cause miscarriage
Avoid during nursing
Use caution with diuretic medications — additive effect
Use caution with diabetes medication — may lower blood sugar
Skip with bladder or kidney inflammation
