Spanish Rusty Foxglove
Digitalis obscura
Digitalis obscura is a plant traditionally unrecorded in any specific medicinal practices. However, studies have shown that its nectar yeast communities are less diverse and dominated by Metschnikowia species, which exhibit higher growth rates despite not being more resistant to the plant's compounds. Cardenolide content varies seasonally, with higher levels observed during summer months compared to winter. Cryopreservation techniques using encapsulation-dehydration have shown varying success among different genotypes of Digitalis obscura, indicating potential variability in recovery rates. Selective extraction from this plant has revealed compounds with antifeedant effects on aphids and nematicidal activity. No major safety issues or drug interactions have been recorded for Digitalis obscura to date.
