After traditional Chinese medicinal materials are processed and prepared into decoction pieces, their surface area increases significantly, making them highly susceptible to moisture absorption and mold growth. Proper storage and preservation have thus become critical to ensuring medicinal efficacy and safety. On August 1, 2025, the shelf-life labeling requirement stipulated in the Provisions on the Labeling Management of Traditional Chinese Medicine Decoction Pieces issued by the National Medical Products Administration officially came into force. This new regulation, together with the escalating technical requirements for warehousing, is driving profound transformation across the traditional Chinese medicine (TCM) decoction piece industry.

The storage of TCM decoction pieces directly impacts drug quality and medication safety. Different types of decoction pieces have stringent requirements for storage environments:

This is the most widely used storage facility for TCM decoction pieces. The vast majority of decoction pieces, especially those containing volatile oils and heat-sensitive varieties prone to deterioration, require storage in a cool environment. In summer, ambient temperatures easily exceed 30°C, and only cold storage can consistently maintain a temperature below 20°C.

Despite being termed "room temperature", this storage type has strict humidity requirements (35%–75%). In humid southern regions or during rainy seasons, natural humidity often surpasses 80%, making it essential to rely on the dehumidification systems of cold storage facilities to maintain safe humidity levels.

Certain unstable decoction pieces highly vulnerable to spoilage—including some animal-derived, resin-based, or decoction pieces prepared from fresh medicinal materials—require refrigerated storage.

Professional storage relies on tailored engineering solutions for pharmaceutical cold storage. Dehezi specializes in customizing pharmaceutical cold storage solutions for clients, delivering personalized storage environments tailored to the characteristics of different decoction pieces to ensure stable quality throughout their shelf life:
