Chemical Composition and Nutritional Profile

Periwinkle contains a variety of bioactive compounds, including alkaloids such as vincamine and vincorine, which are known for their cognitive and neuroprotective effects.

The plant also contains flavonoids, terpenes, and essential oils that contribute to its antioxidant and anti-inflammatory properties. Nutritionally, periwinkle is a good source of vitamins like vitamin C and vitamin A, as well as minerals such as potassium and iron, which support overall health and immune function. These compounds work synergistically in the body to enhance memory, improve blood circulation, and reduce oxidative stress.

The alkaloids in periwinkle inhibit the breakdown of acetylcholine, thereby supporting neural function and cognitive performance.

Medicinal Properties and Health Benefits

Vinca minor has been traditionally used for its medicinal properties, particularly for its effects on the cardiovascular and nervous systems.

It is known to support heart health by improving circulation and reducing the risk of cardiovascular diseases, while also offering mild sedative effects that can help alleviate anxiety and insomnia. Compared to similar herbs like valerian root or passionflower, vinca minor has a more pronounced impact on the circulatory system and provides a more subtle, long-lasting calming effect. Its active compounds, including alkaloids and flavonoids, contribute to its potency in treating conditions related to poor blood flow and stress-related disorders.

While it may not be as widely studied as other herbs, its unique combination of circulatory and calming benefits makes it a valuable addition to herbal medicine practices.

Forms, Preparation and Usage

Vinca minor has been traditionally used in herbal medicine for its purported healing properties, and it is available in various forms including fresh leaves, dried tincture, powder, essential oil, and capsule.

To prepare vinca minor, it can be made into a tea by steeping the dried leaves in hot water, or a decoction can be made by boiling the plant material for a longer period. It can also be used topically as a poultice or in infused oils for skin applications. The recommended dosage for adults is typically 1-2 grams of dried herb per cup of tea, while children should only use it under medical supervision if deemed safe.

Due to limited scientific evidence, it is advised to use vinca minor sparingly, with a duration of no more than a few weeks and not exceeding twice daily.

Safety, Side Effects and Contraindications

Vinca minor can be used with caution due to its potential toxicity, particularly when consumed in large quantities or over prolonged periods.

It contains alkaloids such as vincamine and vincorine, which may cause gastrointestinal upset, dizziness, and even more severe effects like seizures or liver damage in some cases. Individuals using vinca minor should be aware of possible interactions with medications such as anticoagulants, antidepressants, and sedatives, as these combinations may increase the risk of adverse effects. Special populations, including pregnant or breastfeeding women and those with chronic illnesses, should avoid vinca minor due to insufficient safety data and potential risks to fetal or infant development.

To ensure safety, it is advisable to consult a healthcare provider before use, start with low doses, and monitor for any adverse reactions.

Growing, Harvesting and Storage

Vinca minor grows in partial to full shade, thriving in moist, well-drained soil rich in organic matter, and prefers a slightly acidic to neutral pH.

It is a low-maintenance ground cover that spreads rapidly through rhizomes, making it ideal for shady gardens or woodland areas. To ensure healthy growth, it should be watered regularly during dry spells, though it is somewhat drought-tolerant once established. For optimal care, remove dead foliage in early spring and divide the plant every few years to prevent overcrowding. Harvesting should occur in late spring to early summer when the leaves are fully developed but before flowering, using sharp scissors to cut the stems cleanly.

The harvested material should be air-dried in a cool, dark place to preserve its medicinal potency, and stored in a sealed container away from light and moisture.
