Considering the continuous growth in the production and consumption of Gastrodia elata, it's crucial to accurately understand the consumer demand for Gastrodia elata products and develop health products tailored to consumer preferences. In this study, we surveyed 400 consumers each from South Korea and China to gauge their perceptions and buying intentions concerning Gastrodia elata products. The results revealed that Korean consumers predominantly evaluate Gastrodia elata products based on health consciousness, whereas Chinese consumers emphasize the product's external characteristics. In Korea, Gastrodia elata products are mainly promoted for their health benefits and are primarily consumed in ingestible forms. In contrast, in China, Gastrodia elata is frequently used as a culinary ingredient. These findings underscore that consumer perceptions and buying intentions can differ depending on how a product is advertised and presented. Future studies should take into account the evolving international Gastrodia elata market and the surging demand, incorporating diverse countries and cities. It will also be imperative to maintain ongoing monitoring, drawing insights from the industrial growth drive model.

Gastrodia elata, an achlorophyllous orchid plant, is rare medicinal plant. We investigated the genetic diversity in G. elata from 4 locations by using Inter-Simple Sequence Repeats (ISSR) markers. Shannon's information Index (S.I.) indicating genetic diversity ranged from 0.255 (Pocheon) to 0.322 (Muju) with the mean of 0.29. The level of genetic diversity was lower than other plant and most genetic diversity was allocated among individuals within populations (26.81%). The UPGMA dendrogram based on genetic distance failed in showing decisive geographic relationship. In the case of gastrodin (GA), the major components in G. elata, Sangju was highest. The ergothionine (ERG) was detected a lot of contents in Muju and Pocheon. In conclusion, our results is very important information for explaining relationship of genetic variation and functional substances without the effects of environment factors and developing genetic marker by ISSR in G. elata, which may be responsible for the development of breeds with a lot of functional substance in G. elata.
