Retrospect on the research of the cultivation of Gastrodia elata Bl, a rare traditional Chinese medicine.
OBJECTIVE
To review the research on the cultivation of Gastrodia elata Bl, a rare traditional Chinese medicine.


METHODS
The data come from our previous research and published review articles on G. elata cultivation.


METHODS
After reviewing the research results on G. elata from 1960 to 1995, we selected the core research on G. elata and a complete cultivation technique of rare traditional Chinese medicine G. elata.


METHODS
Some important data were arranged in different tables, and new cultivation methods were reviewed.


RESULTS
A. mellea has been found to have inhibiting effects on G. elata seed germination. The seeds are able to sprout only when a nutritional relationship exists between G. elata and a fungus of the same genus as M. osmundicola. The sprouted tubers have to set up a symbiotic relationship with A. mellea during their clone propagation period so as to grow normally.


CONCLUSIONS
G. elata has to symbiosize with M. osmundicola and A. mellea so as to complete its life cycle from seed to seed. These findings have revealed the secret of the life cycle of G. elata that has been puzzling biological circles for years.
