While generally considered safe when used in moderate amounts, it may cause gastrointestinal side effects such as nausea, vomiting, or diarrhea in some individuals.

To ensure safe use, it is recommended to start with small doses, monitor for adverse reactions, and always seek professional medical advice before incorporating it into a treatment regimen.

Growing, Harvesting and Storage

Tropaeolum majus grows best in well-drained, loamy soil that is rich in organic matter, with a pH range of 6.0 to 7.5, and requires full sun to partial shade for optimal growth.

It thrives in temperate climates and needs consistent moisture, especially during the growing season, but should not be overwatered to avoid root rot. Regular pruning and deadheading are essential to encourage continuous blooming and prevent the plant from becoming leggy. The best time to harvest is when the leaves are fully developed but before the plant begins to flower, using sharp scissors or pruning shears to cut the stems just above a leaf node.

For storage, the leaves should be dried in a cool, dark place with low humidity, or frozen in airtight containers to preserve their potency and medicinal properties.
