Hi Friends,

I have some GD that is 6 months old and has not decreased in potency. I do keep mine in the fridge, but I do it out of habit and have no evidence that this increases longevity.

Other herbal tinctures seem to last indefinitely. Think about echinacea extract or vanilla extract; their shelf-life is very long. Other than the fridge (which is probably not necessary), I'd keep it out of sunlight.

Cheers,
Master Wu

The Definitive Green Dragon (Revised, Updated, Combined) Hi Friends, Since I first posted the Definitive Green Dragon 6 months ago, I have received many great comments, answered many questions, and gained more expertise with the extraction myself. I decided it's time to update my recipe and combine my other posts. The biggest change is increasing the extraction temperature from 150-165°F to 170°F. Below is the original recipe (updated). Tips and techniques follow. Thanks for all the feedback and interest. Rating: 5
