中药柜和其家木制中药柜一样，均需进行表面涂饰，一方面是为了美观，作为中药柜，更重要的是保护木材表面，隔断水分与木材的接触，保护木材不产生变形，甚至开裂。但中药柜不同于民用中药柜，与柜子直接接触的是各种药材，不合理的涂饰可能导致涂料成份进入药材中去，影响药理。因此，正确选用涂料显得非常重要。应当选择无有害物质或有害物质含量达标的涂料进行涂饰，涂料也仅限于中药柜外表面的装饰。与药材直接接触的药柜内表面不作涂饰，为了防止水分进入木材，引起中药柜变形和开裂，对可中药柜内表面进行喷蜡处理，因为取自于自然的蜂蜡不含任何对人体有害的物质，对药材药理也没什么影响。
Chinese medicine cabinet and its home wooden cabinet of Chinese medicine, are required to carry out surface painting, on the one hand, for the sake of beauty, as a cabinet of Chinese medicine, more importantly, to protect the surface of the wood, cut off moisture and wood contact, protect the wood from deformation, or even cracking. But the cabinet of traditional Chinese medicine is different from the cabinet of traditional Chinese medicine for civilian use. The cabinet is directly in contact with various medicinal materials. Unreasonable coating may cause the coating ingredients to enter the medicinal materials and affect pharmacology. Therefore, the correct choice of paint is very important. Should choose no harmful substances or harmful substances content standards paint, paint is also limited to traditional Chinese medicine cabinet surface decoration. In order to prevent moisture from entering the wood and causing deformation and cracking of the cabinet, the inner surface of the cabinet was sprayed with wax because the natural beeswax did not contain any harmful substances and had no effect on the pharmacology of the cabinet.
