Forms, Preparation and Usage

Capparis spinosa has been traditionally used for its medicinal properties, with various forms available including fresh leaves, dried tincture, powder, essential oil, and capsule.

It can be prepared as a tea by steeping dried leaves in hot water, or as a decoction by boiling the plant parts for a longer period. Topical applications include using the crushed leaves or essential oil for skin conditions, while the powder can be taken orally. For adults, a recommended dosage is typically 1-2 grams of powder or 1-2 cups of tea per day, though children should only use it under medical supervision if deemed safe.

The duration of use should be conservative, generally not exceeding two weeks without consulting a healthcare professional.

Safety, Side Effects and Contraindications

Capparis spinosa can be used in traditional medicine for its purported digestive and anti-inflammatory properties, but its safety profile requires careful consideration.

While generally considered safe when consumed in moderate amounts, it may cause gastrointestinal side effects such as nausea, vomiting, and stomach cramps in some individuals. There is limited research on its interactions with other drugs or herbs, but caution is advised when combining it with anticoagulants or antiplatelet medications due to potential increases in bleeding risk. Pregnant and breastfeeding women should avoid capparis spinosa due to insufficient evidence on its safety during these periods, and individuals with chronic illnesses should consult a healthcare provider before use.

To ensure safe use, it is recommended to start with small doses, monitor for adverse reactions, and seek professional guidance, especially for long-term or high-dose applications.

Growing, Harvesting and Storage

Capparis spinosa grows in well-drained, slightly acidic to neutral soils in full sun to partial shade, thriving in Mediterranean climates with moderate rainfall.

It requires minimal water once established, making it drought-tolerant, but regular watering during its growing season promotes vigorous growth. Regular pruning is essential to maintain its shape and encourage flowering, while mulching helps retain soil moisture and suppress weeds. The plant is harvested when the fruits are fully mature, typically in late summer to early autumn, by gently twisting or cutting the fruits from the stem to avoid damaging the plant.

For optimal potency, the fruits should be dried in a shaded, well-ventilated area, then stored in airtight containers in a cool, dark place to preserve their medicinal properties.
