Essence: Explosive arterial congestion set off by heat, instantly calmed by cold. Think Glonoinum when sun/heat precipitates a bursting, pulsating head, carotids hammer, face flushes, palpitations surge, the head feels enormous and cannot bear hat/collar/covering, and the patient rushes to cold air or ice with prompt palliation. The mind wanders—gets lost on familiar streets—while the storm rages. Use in sunstroke and its sequelae, climacteric flushes, hypertensive surges, and heat-provoked angina when the heat–cold polarity and jar–rest mechanics are unequivocal [Hering], [Clarke], [Boericke], [Boger], [Nash], [Tyler], [Hughes].
