Why Cast sprays start with a 16-hour herbal infusion


When you use a Cast spray, the scent is the part you notice first. Behind it is another layer of botanical compounds, many of which have little or no noticeable scent at all.

Every Cast formula begins with a 16-hour herbal infusion, a deliberate extraction process that forms the foundation of our approach to physiological wellness.

During the infusion, we carefully manage time and temperature to influence how different plant compounds are extracted. This extended process allows us to draw water-soluble constituents from the botanicals, creating an integral part of the finished formulation.

These constituents include flavonoids, polyphenols, glycosides, and tannins. Their chemical properties inform our botanical selection, allowing us to consider what each plant contributes to the formula beyond its sensory character.

This is where Cast's two-layer architecture comes together. The herbal infusion establishes the botanical foundation, while a composed layer of volatile plant compounds contributes the sensory character of each spray. The finished formulation is designed to engage olfactory pathways associated with autonomic activity, with each product developed for a distinct use state throughout the day.

Sleep, Calm, and Clarity each have their own botanical composition, developed around their intended purpose. The differences begin with the ingredients selected for each infusion and continue through the volatile layer, giving every formula its own composition within the Cast system.
