Safety, Side Effects and Contraindications

Citrus x aurantium, commonly known as bitter orange, can be used medicinally for its potential effects on mood and metabolism, but it carries significant safety concerns.

It may cause side effects such as increased heart rate, insomnia, anxiety, and gastrointestinal discomfort due to its high content of synephrine and other alkaloids. It should be avoided with certain medications like stimulants, antidepressants, and blood pressure drugs, as it may interact adversely, increasing the risk of cardiovascular complications. During pregnancy and breastfeeding, bitter orange is contraindicated due to potential risks to fetal or infant development, and individuals with chronic illnesses such as hypertension or heart disease should consult a healthcare provider before use.

To ensure safe use, it is recommended to consult a qualified healthcare professional, start with low doses, and monitor for adverse reactions closely.

Growing, Harvesting and Storage

Citrus x 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 regions with warm climates and moderate rainfall, needing regular watering during dry periods while avoiding waterlogging to prevent root rot. Regular pruning and fertilization with a balanced citrus-specific fertilizer promote healthy growth and increase fruit yield. Harvesting should occur when the fruits are fully mature, typically in late summer to early fall, using sharp pruning shears to cut the fruit from the branch without damaging the plant.

To preserve potency, harvested fruits should be dried in a cool, shaded area or stored in airtight containers in a cool, dark place, or refrigerated to extend shelf life and maintain medicinal properties.
