How long can dried Cornus officinalis (Chinese cornel) be stored?

    Air-dried Cornus officinalis (Chinese cornel) can typically be stored for 3 to 12 months, although the exact duration may vary.

    When properly stored, the shelf life of air-dried Cornus officinalis is generally at least 3 to 12 months. This is because Cornus officinalis, as a traditional Chinese medicinal material, has relatively stable medicinal properties, and after air-drying, its moisture content is reduced, which helps prolong storage time. However, the shelf life of air-dried Cornus officinalis is also affected by storage conditions.

    If the Cornus officinalis has been thoroughly dried with no residual moisture and is stored in a cool, dry, and well-ventilated place, away from direct sunlight and humid environments, it can be preserved for a longer period, even several years. Under such conditions, the Cornus officinalis is less likely to mold or deteriorate and can maintain its medicinal properties and efficacy well. However, improper storage conditions, such as high temperatures, humidity, or exposure to sunlight, may accelerate its deterioration.

    To ensure the quality and safety of air-dried Cornus officinalis, it is recommended to regularly inspect its condition, and any signs of deterioration should prompt immediate disposal or use. Before consumption, carefully examine the appearance and odor of the Cornus officinalis to ensure it is in optimal condition.
