Opening the guide…
A little shelf-sense so your work lasts.
Name and date every jar and bottle the moment you make it. Memory is not a labeling system.
Light, heat, and moisture are what spoil remedies. A cupboard beats a windowsill.
Dried herbs ~1 year, infused oils ~1 year, tinctures several years, salves ~1 year. Trust your senses.
Off smells, cloudiness, or mold mean it's done. Start fresh rather than risk it.
