Juniper berries have been proven through research to contain beneficial substances that are good for you. The research about juniper berries is lacking on the whole but there is some research that has shown some interesting results.
Most of the junipers are edible, but you can also find poisonous junipers. You can eat the juniper berries as they are, but if you have a problem with your kidneys or other health issues you need to be careful.
Something I find amusing with the juniper berries is they aren’t berries, they are cones!
I’ve seen these bushes since I was a child. I was never fond of them, because of their sharp needles. They can really scratch you if you aren’t careful.
Where we live, many people have juniper berry bushes as hedges around their gardens. Some have them as ornamental bushes. They also grow wild. Who knows, those sharp needles might fend of an intruder or two as well.

Benefits Of Juniper Berries
An extensive review was made on all research, journals and various books updating on Juniperus Communis as a medicinal plant. The research team listed a number of pharmacological activities and health benefits against various diseases.
Here’s some of the most interesting findings in the review.
Juniper berries are diuretic
Juniper berries increase the flow of urine. This can help to cleanse the system of excess fluids and stimulate the kidneys. This causes the body to flush out uric acid and excess crystals that can cause problems, for instance arthritis or kidney stones.
Juniper berries have anti-inflammatory properties
Anti-inflammatory is the property of a substance or treatment that reduces inflammation or swelling.
Juniperus communis shows anti-inflammatory properties but its level of activity varies quite a lot. This means that more research is needed to establish if and how we could be able to benefit from it.
Juniper berries have antifungal properties
With antifungal activity means a compound that is destroying fungi or inhibiting their growth.
The essential oils obtained from Juniperus communis show antifungal activity against two tested fungi, Rhizoctonia solani and Rhizopus stolonifer.
Rhizoctonia solani causes a wide range of commercially significant plant diseases. Many countries experience great food losses caused by this fungi every year.
Rhizopus stolonifer, also known as black bread mold, is a common agent of decomposition of stored foods.
Juniper berries have analgesic properties
Analgesics are agents which selectively relieve pain by acting in the central nervous system and peripheral pain mediators.
Methanolic extract of Juniperus communis have been reported to contain analgesic properties.
Juniper berries are antidiabetic
An antidiabetic agent is any substance that helps people with diabetes control the level of sugar in their blood.
Methanolic extract of Juniperus communis shows a significant antidiabetic activity, which needs further research.
Juniper berries have antihyperlipidemic properties
Antihyperlipidemic agents promote reduction of lipid levels in the blood. This means that it lowers the level of cholesterol in the blood by reducing the production of cholesterol by the liver.
Methanolic extract of Juniperus communis shows a significant antihyperlipidemic activity.
Juniper berries have antimicrobial properties
An antimicrobial is an agent that kills or stops the growth of microorganisms.
The berries of Juniperus communis were reported to have antimicrobial properties and volatile oils. These studies show that Juniperus communis was active against bacteria like, Escherichia coli, Staphylococcus aureus, and Hafnia alvei.
Juniper berries have antioxidant properties
Antioxidants are compounds that inhibit oxidation. Antioxidant activity is defined “as a limitation of the oxidation of proteins, lipids, DNA or other molecules that occurs by blocking the propagation stage in oxidative chain reactions”
The antioxidant effects of the juniper berry oil of Juniperus communis was confirmed by a study and created the possibility of blocking the oxidation processes in yeast cells by increasing the activity of the antioxidant enzymes.
Juniper berries have antibacterial properties
Antibacterial is anything that destroys bacteria or suppresses their growth or their ability to reproduce. Heat, chemicals such as chlorine, and antibiotic drugs all have antibacterial properties.
It’s been estimated that extracts of leaves of Juniperus communis are effective against some pathogenic bacteria.
The methanolic extract of Juniperus communis was found to be very effective as compared to standard antibiotics.
Juniper berries shows neuroprotective properties in Parkinson's disease
The term neuroprotection comes from the Greek word 'neuron', meaning nerve cell, and 'protection'. It refers to mechanisms within the nervous system which protect neurons from degeneration.
In the context of Parkinson's, neuroprotection refers to any intervention which prevents or slows the death of dopamine-producing cells.
Neuroprotective activity of Juniperus communis was evaluated in chlorpromazine induced Parkinson's model in rats. Juniperus communis showed a significant neuroprotective effect against induced Parkinson's like symptoms. (source)
As you can see above Juniper berries show quite a lot of interesting properties. We can conclude that Juniperus communis shows promise as a medicinal plant. But there needs to be more research done.
How Is Juniper Berries Used? (Medicinal Uses)
Juniper berries are said to have antiseptic capabilities and are therefore believed to help with urinary tract infections and cystitis.
It's also said that the berries can increase blood circulation in the skin. This is believed to make junipers berries good for various skin problems such as oily skin or eczema. Better blood circulation also contributes to better healing.
