Overview

Juniper is a tree that grows wild in some parts of Europe, North America, and Asia. There are many varieties of juniper, but Juniperus communis is the most common in North America.

Don't confuse juniper berry oil with cade oil, which is distilled from juniper wood (Juniperus oxycedrus).

Some people take juniper by mouth for problems with digestion, urinary tract infections (UTIs), kidney stones, and many other conditions, but there is no good scientific evidence to support these uses.

In foods, juniper berry is often used as a condiment. The extract, oil, and berry are used as flavoring ingredients in foods and beverages.

In manufacturing, juniper extract and oil are used as fragrances in soaps and cosmetics.

Interactions ?

    Moderate Interaction

    Be cautious with this combination

  • Medications for diabetes (Antidiabetes drugs) interacts with JUNIPER

    Juniper might decrease blood sugar. Diabetes medications are also used to lower blood sugar. Taking juniper along with diabetes medications might cause your blood sugar to go too low. Monitor your blood sugar closely. The dose of your diabetes medication might need to be changed.

    Some medications used for diabetes include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.

    Minor Interaction

    Be watchful with this combination

  • Water pills (Diuretic drugs) interacts with JUNIPER

    Juniper seems to work like "water pills" by causing the body to lose water. Taking juniper along with other "water pills" might cause the body to lose too much water. Losing too much water can cause you to be dizzy and your blood pressure to go too low.

    Some "water pills" include chlorothiazide (Diuril), chlorthalidone (Thalitone), furosemide (Lasix), hydrochlorothiazide (HCTZ, Hydrodiuril, Microzide), and others.

  • Lithium interacts with JUNIPER

    Juniper might have an effect like a water pill or "diuretic." Taking juniper might decrease how well the body gets rid of lithium. This could increase how much lithium is in the body and result in serious side effects. Talk with your healthcare provider before using this product if you are taking lithium. Your lithium dose might need to be changed.

Dosing

The appropriate dose of juniper depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for juniper. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
