Objectives: The purpose of this research was to examine the oriental medical term ’Yukjin(in chinese, liuchen)’ i.e. ’good long-term storage of the six oriental medicinal herbs’. Yukjin has meant the six sorts of drugs which were well known for the older they stored, the better efficacious they were. This research was carried out to obtain more conclusive information about the time and the reason of the giving a naming Yukjin, and to arrange Yukjin’s properties, toxicities and processes.
Methods: We investigated the documents recorded in the medical classics of Yukjin and did the current issues and recent experimental researches of these medicines.
Results: 1. The properties and flavors of Yukjin are pungent and bitter. When they were stored for a long time after gathering, their toxicities and stimuli were growing thinner, regarded as positive clinically with age and they should be used after processing. 2. The efficacies of Yukjin are not always in proportion to storage period. In case, they are stored too long, their efficacies and qualities may be deteriorated though volatility or pungent flavors are enfeebled.
Conclusions: Consequently, toxicities and strong flavors of Yukjin can be reduced in various processes. So the traditional theory of long-term preservation is not necessarily retained. It may be desirable to store them for 1 to 3 years after harvest, to safen their toxicities and adverse reactions in the way of processing. If we use them properly according to oriental medicine method, it will be effective on treating and preventing the various diseases.
