What fundamental contrast exists between the implied primary uses of Salal berries versus the leaves?

Answer

Berries for nutrition and sustenance, leaves for medicinal teas/tonics

The traditional uses of the different parts of Gaultheria shallon clearly delineate roles based on the plant component. The berries were integrated into the diet as a significant source of nutrition, often preserved as food stores (cakes). Conversely, the leaves were prepared specifically as infusions—salal tea—suggesting a role aligned with traditional remedies intended for targeted internal support or toning, rather than bulk sustenance. This distinction highlights a practical division of labor: fruit for the body's energy needs, and leaves for specific internal wellness applications.
