How should I store this neem powder and how long does it last?

The powder stays stable when kept dry and protected from humidity. Store it in its original container with the lid sealed completely, away from direct sunlight and heat sources like radiators or bathroom steam. Once opened, some customers prefer refrigerating the container to minimize moisture exposure and preserve the herb's potency, though this isn't strictly required.

Because this is a single-ingredient botanical powder without preservatives, freshness depends on storage conditions. When stored properly, the powder typically remains effective for 12-18 months. Signs of degradation include clumping, unusual odor, or visible mold—if any appear, discontinue use.

For best results, use a clean, dry spoon or measuring tool when scooping out portions. Introducing moisture or contaminants can shorten shelf life and potentially cause spoilage. If you're traveling or want smaller amounts on hand, portion the powder into an airtight container for single-use quantities.
