Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C)
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Comparison on Chemical Constituents and Pharmacological Effect of Gastrodiae Rhizoma Between Traditional Processing and Integration Processing[Reference: WebLink
To elucidate the rationality of integration processing technology based on comparison on chemical constituents and pharmacological effect of Gastrodiae Rhizoma between traditional processing and integration processing.
METHODS AND RESULTS:
Taking contents of gastrodin and parishins as indexes,chemical constituents difference in Gastrodiae Rhizoma between traditional processing and integration processing was compared,effects of Gastrodiae Rhizoma on eclampsia model induced by pentylenetetrazole were observed to compare products with different processing technology. Contents of gastrodin,Parishin A,parishin B,parishin C and parishin E in products of integration processing were 0. 79%,2. 04%,0. 91%,0. 23% and0. 57%,they were 0. 39%,1. 12%,0. 64%,0. 15% and 0. 54% in products of traditional processing. The anti-eclampsia effect of Gastrodiae Rhizoma produced with integrated processing technology was better thantraditional processing technology.
Compared with the traditional processing technology, the integrated processing technology is better in guaranteeing the quality of pieces,reducing the cost of production and increasing the production efficiency.
