Medicinal Properties and Health Benefits

Citrus aurantium has been traditionally used for its stimulating and circulatory benefits, primarily due to its high concentration of bioactive compounds such as flavonoids and alkaloids like synephrine.

It is known to support cardiovascular health by improving blood flow and enhancing metabolic rate, making it beneficial for individuals seeking to manage weight or increase energy levels. Compared to other citrus herbs like grapefruit or lemon, citrus aurantium offers a more potent stimulant effect, though it may also cause mild side effects in higher doses.

Forms, Preparation and Usage

It can be prepared by making tea, decoction, or infusion, while the essential oil and powder are often used topically for skin conditions or aromatherapy. For adults, a typical dosage might range from 1 to 2 grams of dried fruit or 10 to 20 drops of essential oil, while children should only use it under medical supervision.

Safety, Side Effects and Contraindications

Citrus aurantium can be used in various forms, such as supplements or extracts, to support mood regulation and weight management, but it is important to be aware of its safety profile.

While generally considered safe when used in recommended doses for short periods, citrus aurantium may cause side effects such as gastrointestinal upset, increased heart rate, and insomnia due to its high concentration of synephrine. It may interact with certain medications, including beta-blockers and antidepressants, potentially leading to adverse effects, and should not be combined with other stimulant herbs like ephedra or guarana. Special populations, including pregnant or breastfeeding women and individuals with chronic illnesses such as heart disease or hypertension, should avoid its use due to potential risks.

For safe use, it is advisable to consult a healthcare professional before starting citrus aurantium, follow recommended dosages, and discontinue use if any adverse reactions occur.

Growing, Harvesting and Storage

Citrus aurantium grows best in well-drained, loamy soil with a pH between 6.0 and 7.5, requiring full sun exposure for optimal growth and fruit development.

It thrives in warm climates with consistent temperatures above 15°C, and regular watering is necessary, especially during dry periods, though overwatering should be avoided to prevent root rot. Regular pruning and fertilization with a balanced citrus fertilizer during the growing season help maintain plant health and encourage fruiting. Harvesting occurs when the fruit turns from green to a vibrant red or orange, typically in late summer to early autumn; fruits are picked by hand to avoid damage.

For storage, citrus aurantium should be dried in a shaded, well-ventilated area to preserve potency, then stored in airtight containers in a cool, dark place or refrigerated to extend shelf life and maintain medicinal properties.
