Roots required proper storage to maintain potency. Most were dried—cleaned carefully, sliced to increase surface area, spread in well-ventilated area away from direct sunlight, allowed to dry completely before storage. The drying removed moisture that would encourage rot or mold, concentrated active compounds, reduced weight and volume making storage more efficient. Properly dried roots could maintain potency for years if stored in cool, dark, dry conditions.
Some roots required different preservation methods. Those containing volatile compounds that would be lost through drying were preserved in alcohol, creating tinctures that maintained compound stability. Others were better preserved fresh, stored in cool cellars, used relatively quickly before decay began. The optimal preservation method varied by species and intended application, the healer learning which roots tolerated which storage methods, adjusting preservation technique to maintain maximum medicinal value.
The storage containers mattered. Roots stored in light-permeable containers degraded faster, some compounds breaking down when exposed to light. Those stored in humid conditions absorbed moisture, creating mold problems. The proper storage required dark containers, airtight seals where appropriate, cool temperatures, regular inspection to catch deterioration before entire stored supply was lost.
