Harvesting and processing
- Harvest
- Summer (May-June) when the buds are about to open
Floral buds collected in the morning when they have the characteristic white-yellow bicolor color but before opening completely. The opening reduces the concentration of chlorogenic and luteolin. They dry immediately.
Floral buds spread in thin layers, dried quickly in the shade or with gentle heat (40-50°C) to fix the color and preserve the chlorogenic acid. Slow drying causes blackening.
Cocoons fried over high heat until they are black on the outside while maintaining a brown interior. Rarely used; only for hemorrhagic diarrhea due to toxic heat.
