Written by Varsha Patnaik , MSc (Biotechnology), Certified Diet & Nutrition Coach

Juniperus communis, better known as juniper, is an evergreen shrub that grows wildly in parts of Europe, Asia, and North America. The fruits that grow on this shrub are called juniper berries. These berries have a deep blue color and have a very woody, earthy, and spicy aroma.

Let us understand more about juniper berries.

What Is Juniper Berry?

The juniper tree is dioecious, which means that the male flowers and female flowers grow on separate plants. The male juniper plant produces cones that are smaller in size when compared to cones produced by the female juniper plant. These cones from the male plant are inedible as they are little sacks of pollen. On the other hand, the female cones are relatively larger in size and ripen into what you know as juniper berries. These cones, initially green, take about 18 months to ripen and turn into round and oval-shaped juniper berries that are dark blue in color and have a white-ish waxy coating on their skin.

While most varieties of juniper berries are edible, juniperus oxycedrus and juniperus sabina are not safe to be consumed.

Let us look at some of the nutritional facts of juniper berries and how to go about using them.

Monoterpenes are compounds that are found in the essential oils of many plants, vegetables, and fruits. This compound is known to treat and prevent carcinogenic activities at different stages of cancer. Studies suggest that monoterpenes may help in the prevention and treatment of cancer (3).

Vitamin C also helps in protecting your skin from UV-induced photodamage. It is a good antioxidant that helps in keeping your cells protected from free radicals (5).

These berries are also rich in flavonoids that offer a wide range of health benefits. By incorporating a diet that is rich in flavonoids you may be able to protect yourself from chronic heart diseases. A study was conducted to ascertain the effects of flavonoids on reducing diabetes, cancer, cardiovascular, and brain diseases. It was found that when consumed in its natural form or synthesized from, flavonoids helped reduce some of the symptoms of these diseases. The study also pointed out that further research was required to begin clinically testing the effectiveness of flavonoids in treating these diseases (6).

2. Anti-inflammatory Properties

Juniper berries contain essential oils and antioxidants that give them anti-inflammatory properties. These essential oils have been used for medicinal and flavoring purposes as well. They help in the prevention of oxidation of cells that cause rapid cell damage and also protect the cells from free radicals that cause tissue damage (7).

Juniper berry oil has been used as an ingredient in skincare products and cosmetics due to its anti-inflammatory values. Studies show that juniper berry oil has a therapeutic effect on chronic inflammation and fibrosis (8).

3. Potentially Anti-diabetic

Juniper berries are known to have been used in traditional medicine to treat diabetes. A study was conducted on rats to ascertain the anti-diabetic effect of juniper berry extracts. During the study, rats with diabetes were fed extracts of juniper berry for 21 days and it was found that there was a considerable reduction in their blood glucose levels. The study helped in affirming the anti-diabetic properties present in juniper berry extracts and that it can potentially be used to treat type 2 diabetes (9). However, further trials are required to confirm if they have the same effects on the human body.

4. May Protect Your Heart Health

Juniper berries may improve your heart health by improving your HDL levels and reducing your LDL levels. HDL stands for high-density lipoprotein, which is also called good cholesterol.  HDL absorbs excess cholesterol and moves it to your liver. Your liver processes it and flushes it out of your body. It is good to have higher levels of HDL cholesterol as it reduces your risk of heart diseases and stroke. LDL stands for low-density lipoprotein, also known as bad cholesterol. High levels of LDL cholesterol are bad for you as they put you at a greater risk of getting a heart attack or a stroke (10).

In a study conducted on rats induced with diabetes, it was found that oral administration of Chinese juniper berry extracts led to a decrease in triglyceride and cholesterol by 37% and 57% respectively (11). However further research is required to ascertain if consuming juniper berries will have the same effect on the cholesterol and triglyceride levels of human beings.

5. Antibacterial, Antifungal, And Good For Your Gut

The essential oils of juniper berries are also known for having these properties due to the presence of a compound called terpenes. Terpenes also make the essential oils of the juniper berry an effective diuretic. This helps in improving your kidney function and intestinal function (12).

While the potential health benefits of juniper berries sound very alluring, it must be noted that sufficient tests are not available to prove the efficacy of these benefits on human subjects. Hence these are only the potential and emerging benefits of juniper berries.
