Hey PureSkunk!  Cool thread.  Its fun to read through and hear discussion from years ago.  Beautiful cactus you have there!  I think its awesome that you've been growing them for years.

I hope you can find some answers to your questions about extractions and resin.  I always just brew the tea.  Its easy and effective.  And you can reduce it down to just a few ounces to drink.  But I understand you wanting to avoid the bad taste.  The taste is pretty bad. 

Anyway all the best with finding a method that works for you.  Please let us know how it all turns out!
