Harvesting and storage of raw materials

Impurities. Blue cow wheat (Melampyrum nemorosum L.) from birdwort family (Scrophulariaceae), is not allowed to harvest. It has a higher (up to 50 cm) stem, double-lipped yellow flowers with purple bracts gathered in a spike inflorescence, and lanceolate leaves located opposite. Security measures. The frequency of harvesting of the raw materials on the same areas for 2 years.
Drying. Under a canopy with good ventilation or in attics under an iron roof. The raw materials are spread out a layer of 5-7 cm and periodically mixed. The raw materials are considered dried if the stems break easily when bent. The yield of dry raw materials 20-22%. Artificial drying is allowed at a temperature not higher than 40 ºС.
Storage. Ii is stored in dry and well-ventilated areas.
