The wild prunes of the prunus spinosa refresh walkers and are a fall food for doves, thrushes, and other birds. They have a slightly rough but pleasant flavor. Their medicinal properties are not extraordinary, and physical exercise could produce their effects when gathering them. However, this humble and happy wild fruit is worth taking advantage of.
Prunus Spinosa Scientific Facts
- Scientific Name: Prunus spinosa L.
- Other Names: Sloe, blackthorn.
- French: Prunellier noir, sauvage.
- Spanish: Endrino.
- Environment: Common on sunny slopes and roadsides of the European mountainous regions. Naturalized in America.
- Description: The shrub of the Rosaceae family grows from one to three meters high, with dark-ochre bark and many woody thorns. Its flowers are ivory-white and small. The fruit is a round berry, dark blue when ripe.
- Parts of the plant used medicinally: The flowers and the fruits (sloes).
Prunus Spinosa Benefits
The flowers of this plant contain amygdalin (a cyanogenetic glycoside), coumarin derivatives, and flavonic glycosides. They have laxative, diuretic, and depurative properties. The laxative properties are mild and are accompanied by an antispasmodic (relaxing) action on the muscles covering the large intestine. They are highly recommended for spasm-caused constipation in the so-called irritable colon.
The FRUIT (sloes) contain tannin (hence their strong flavor), flavonic substances, malic acid, saccharose, pectin, gum, and vitamin C. Unlike the flowers, they have astringent properties, being thus helpful for mild diarrhea and intestinal upset. Moreover, they have eupeptic (stimulate digestive processes), appetizer, and invigorating properties of the entire body.
Prunus spinosa berries give those people eating them an increased appetite and an invigorating and refreshing feeling. They can be eaten fresh, cooked, or used as syrup.
The liquid obtained from the sloes decoction is used to stop epistaxis (nasal hemorrhages) by soaking a nasal packing. It is also helpful for gargles and rinses to treat gingivitis (inflammation of the gums) and pharyngitis.
Warning
Like many others in the Rosaceae family, the sloes’ almonds liberate hydrocyanic acid, a potent poison. So, they must never be eaten or ground. The bark of the branches and the root also contains hydrocyanic or prussic acids, another toxic substance. Therefore, the bark must not be used, although some recommend it as an astringent substance.
How to use Prunus Spinosa
- Infusion with 60 grams of flowers per liter of water. Drink a cup in the morning every day.
- Fruits – Sloes can be eaten fresh or boiled in water (only two minutes) to eliminate their rough flavor.
- Syrup, prepared with half a kg of fruits, the same amount of sugar, and a glass of water. Boil the mixture for 15 minutes. The resulting red, pleasantly tasting syrup must be strained and taken by spoonfuls as an antidiarrheic or appetizer.
- Decoction with 100 sloes per liter of water, boiling on low heat for 10 minutes. Strain and take by the spoonful.
- Nasal plugging with gauze soaked in the decoction mentioned above.
- Mouth rinses and gargles, with the decoction used in internal applications.
Freshly cooked or in the form of syrup, sloes are appetizing and stimulate digestive processes.
Frequently Asked Questions
What are the primary active compounds in Prunus spinosa that are linked to health benefits?
Prunus spinosa contains several potentially beneficial compounds:
1. Flavonoids: Anthocyanins, quercetin, and others with antioxidant and anti-inflammatory effects.
2. Tannins: Provide astringent properties and may have antimicrobial effects.
3. Vitamin C: An essential antioxidant.
4. Fiber: Mostly from the fruits, supporting gut health
5. Trace amounts of amygdalin: A cyanogenic glycoside; potential use is controversial and requires proper handling to avoid releasing cyanide.
How does the preparation method (infusions, decoctions, tinctures, etc.) influence the compounds extracted from Prunus spinosa?
The method matters!
1. Infusions (hot water steeping): Best for leaves and flowers to extract flavonoids, some tannins, and vitamin C.
2. Decoctions (boiling): Extracts more tannins from bark/roots but can degrade some heat-sensitive compounds.
3. Tinctures (alcohol extraction): Excellent for a broader range of compounds, including less water-soluble ones; longer shelf-life.
What are the most well-supported digestive benefits of Prunus spinosa?
Prunus spinosa exhibits several actions in the digestive system:
1. Mild laxative: Especially fruit, due to fiber and possibly other compounds.
2. Astringent: Tannins tighten tissues, potentially helpful for mild diarrhea.
3. Antispasmodic: May calm intestinal cramping (more research is needed to confirm this in humans).
Could Prunus spinosa play a role in managing blood sugar?
Research is limited but promising. Preliminary studies suggest potential benefits:
1. Blood sugar reduction: Some animal studies show blood sugar lowering effects.
2. Insulin sensitivity: Possible improvements seen in minimal studies.
Important: It does NOT replace conventional diabetes medication; more human studies are needed.
How might Prunus spinosa benefit cardiovascular health?
Potential benefits are primarily linked to the antioxidant and anti-inflammatory effects of flavonoids:
1. Blood pressure: Some evidence for mild blood pressure reduction.
2. Cholesterol: Potential to improve lipid profiles, but more research is needed.
3. Blood vessel health: Antioxidants protect against damage, which is essential for overall heart health.
Are there traditional uses of Prunus spinosa for immune health?
1. Traditionally, blackthorn was used for colds, coughs, and general immune support.
2. Vitamin C is an antioxidant and vital for the immune system.
3. Anti-inflammatory effects: This may help reduce the severity of specific symptoms.
Note: There is insufficient research to consider it a cure or treatment for specific illnesses.
Does Prunus spinosa have any topical applications?
1. Mouthwash: Astringent properties are helpful for sore throats and mouth irritation.
2. Skincare: Possibly for wound healing and soothing inflammation (more research is needed to establish safety and efficacy).
What are the likely side effects of using Prunus spinosa?
Generally considered safe in moderate amounts, but be aware of:
1. Digestive Upset: In some people, especially if consuming large quantities of unripe fruits.
2. Medication Interactions: Tannins can potentially interfere with specific drug absorption (talk to your doctor).
3. Amygdalin: To prevent the release of cyanide, leaves, flowers, and kernels containing amygdalin must be handled carefully.
Is Prunus spinosa safe for pregnant or breastfeeding women?
More research is needed. There’s insufficient safety data to recommend it during pregnancy and breastfeeding. Consultation with a doctor is essential.
