Question 3

How does Squill work?

Accepted Answer

Cardiac Mechanism

The primary active constituents in this botanical are cardiac glycosides, specifically scillaren A and scillaren B. These substances exert a positive inotropic effect, which means they increase the force and velocity of myocardial contractions. Simultaneously, they produce a negative chronotropic effect, slowing the heart rate. This dual action helps the heart pump more efficiently by strengthening the muscle's output while regulating its rhythm.

Respiratory Action

The ingredient is also recognized for its expectorant properties. It is believed to work by irritating the gastric mucosa, which triggers a reflex stimulation of the bronchial glands. This process increases the volume of fluid secreted in the respiratory tract, thinning mucus and making it easier to expel through coughing.

Diuretic Properties

By improving the efficiency of the heart's pumping action, this compound may also promote diuresis. The increased cardiac output enhances blood flow to the kidneys, which can lead to an increase in urine production and a reduction in fluid retention.
