  STORAGE

Pau d'Arco, like many other herbs, requires proper storage to maintain its properties for a longer period. It is best to store the bark in a dry and cool place, away from heat sources and moisture. Storing it in tightly sealed containers is recommended to prevent air and other contaminants from entering. Avoid storing Pau d'Arco bark in bright or sunny places, as light can degrade some of its active components.
