The Bronchial Relaxant of Ancient Physician Dioscorides

Documented by Dioscorides under the ancient Greek name Melanthion for treating chest tightness and shortness of breath, Nigella sativa contains specialized carbonyl polymers formed by the condensation of thymoquinone: Nigellone (polythymoquinone).
  1. Antagonism of Voltage-Gated L-Type Calcium Channels: Nigellone blocks extracellular calcium influx into tracheobronchial smooth muscle cells, terminating spastic muscular contractions.
  2. Cyclic AMP Accumulation: It stimulates intracellular adenylate cyclase, elevating cyclic adenosine monophosphate (cAMP) and promoting effortless, relaxed respiratory airflow.
