These compounds work synergistically in the body to enhance blood flow, support nerve function, and reduce oxidative stress. The alkaloids in periwinkle inhibit certain enzymes and neurotransmitter reuptake, making it beneficial for improving memory and cognitive performance.

Forms, Preparation and Usage

Vinca minor has been traditionally used in herbal medicine for its purported therapeutic properties, and it is available in various forms including fresh plant, dried tincture, powder, essential oil, and capsule. To prepare vinca minor, it can be made into a tea by steeping dried leaves and flowers in hot water, or a decoction can be made by boiling the dried plant material for a longer period. Topical applications include using the plant as a poultice or applying diluted essential oil directly to the skin for localized effects. The recommended dosage for adults is typically 1-2 grams of dried herb per cup of tea, while children should only use it under professional supervision if deemed safe. Due to the potential for adverse effects, it is advised to use vinca minor sparingly, with a duration of use not exceeding a few weeks unless directed by a healthcare provider.

Safety, Side Effects and Contraindications

Vinca minor can be used with caution due to its potential toxicity, particularly due to the presence of alkaloids such as vincamine and vincadifformin, which may affect the central nervous system and cardiovascular system. Common side effects include dizziness, nausea, vomiting, and gastrointestinal discomfort, while more severe reactions may involve heart palpitations or even cardiac arrhythmias. It may interact with medications such as antidepressants, anticoagulants, and sedatives, increasing the risk of adverse effects or reduced efficacy. Pregnant and breastfeeding women should avoid vinca minor due to limited safety data and potential harm to the fetus or infant, while individuals with chronic illnesses like heart disease or hypertension should consult a healthcare provider before use. To ensure safe use, it is advisable to consult a qualified healthcare professional, start with low doses, and monitor for any adverse reactions, especially when combining with other herbs or medications.

Growing, Harvesting and Storage

Vinca minor grows best in partial to full shade, thriving in moist, well-drained soil rich in organic matter, and prefers a slightly acidic to neutral pH. It requires regular watering, especially during dry periods, but should not be overwatered to avoid root rot. To ensure healthy growth, mulching around the base of the plant helps retain moisture and suppress weeds, while pruning dead or damaged foliage in early spring promotes vigorous growth. The best time to harvest vinca minor is in late summer to early autumn when the leaves are mature and the plant is at its peak potency, using clean, sharp shears to cut the stems just above a leaf node. After harvesting, the leaves should be spread out in a cool, dry place to dry thoroughly, then stored in airtight containers in a cool, dark location to preserve their medicinal properties.
