Forms, Preparation and Usage
Helianthus annuus has been utilized for its therapeutic properties in various forms, including fresh plant material, dried tincture, powder, essential oil, and capsule.
It can be prepared as a tea by steeping dried flowers in hot water, or as a decoction by simmering the plant parts for a longer period.

Safety, Side Effects and Contraindications
Helianthus annuus can be used as a medicinal plant for its potential therapeutic effects, such as reducing inflammation and supporting cardiovascular health, but it should be used with caution.
While generally safe when consumed in moderate amounts, it may cause side effects such as gastrointestinal upset, allergic reactions, or photosensitivity in some individuals. It may interact with medications like blood thinners or antidiabetic drugs, so caution is needed when combining it with other herbs or pharmaceuticals. Special populations, including pregnant or breastfeeding women and individuals with chronic illnesses, should avoid its use due to limited safety data and potential risks.
To ensure safe use, consult a healthcare provider before incorporating helianthus annuus into a regimen, and follow recommended dosages to minimize adverse effects.
Growing, Harvesting and Storage
Helianthus annuus grows best in well-drained soil with a pH between 6.
0 and 7. 5, requiring full sun exposure and consistent moisture during the growing season. It thrives in temperate climates and should be planted in spring after the last frost, with spacing of about 30 to 60 cm between plants to allow for adequate air circulation. Regular watering is essential, especially during dry periods, but overwatering should be avoided to prevent root rot. To maintain healthy growth, remove any dead or diseased leaves and ensure the plants are not overcrowded. The best time to harvest is when the back of the flower head turns from green to brown, using clean shears to cut the flower heads just below the base, ensuring the seeds are fully developed but not overly dry.
For optimal potency, the harvested seeds should be spread in a single layer on a screen in a cool, dry place to dry completely, then stored in airtight containers in a cool, dark location to preserve their medicinal properties.
