Harvesting method: Stalk with leaves are harvested with garden shears at the beginning of flowering.

Drying: It is dried in thin layers in a shady place. During artificial drying, the temperature must not exceed 35 °C.

Active substances: The fresh plant contains melilotoside, which decomposes when dried to release fragrant coumarin. We find bitter-tasting iridoid substances such as asperuloside and monotropein in the plant. Flavonoids, tannins and various phenolic acid derivatives are also present.

Uses: Coumarin in the drug provides antiphlogistic effects. Marigold works against swelling, spasms, restlessness and insomnia.
