While generally considered safe when used in appropriate doses, it may cause mild side effects such as gastrointestinal discomfort, nausea, or allergic reactions in some individuals. There is limited research on interactions with other drugs or herbs, but caution is advised when combining it with anticoagulants or sedatives due to potential additive effects. Special populations, including pregnant or breastfeeding women and individuals with chronic illnesses, should avoid its use without medical supervision, as its safety in these groups has not been thoroughly established.

To ensure safe use, always consult a healthcare provider before taking cornus florida, start with low doses, and monitor for any adverse reactions.

Growing, Harvesting and Storage

Cornus florida grows best in well-drained, fertile soil with a slightly acidic to neutral pH, in full sun to partial shade, and requires regular watering during the growing season to maintain consistent moisture without becoming waterlogged.

It thrives in temperate climates and benefits from mulching to retain soil moisture and suppress weeds. To ensure healthy growth, prune dead or diseased branches in early spring and fertilize annually with a balanced, slow-release fertilizer. The best time to harvest Cornus florida is in late spring to early summer when the flowers are fully open, using pruning shears to cut the stems just below the flower heads to encourage future blooms.

After harvesting, the flowers should be dried in a cool, dark place with good air circulation to preserve their potency, and stored in airtight containers away from light and moisture to maintain their medicinal properties.
