...comparison. 300 seed (Heavenly Blue) extractions. Attempt One: Cold Water Extraction Method: Finely ground seed solution was agitated for 5-10 minutes in a small glass, then filtered through a manual drip coffee cone filter (taking another 10 minutes). Results: Weak. Disappointing. Attempt Two: Two-step alcohol extraction Method: Finely ground seed was soaked in xylol (didn't have Naphtha handy) for 5 minutes and agitated (swooshed around in a glass jar), then filtered through a coffee filter. The grounds were then dried COMPLETELY on a paper plate, then soaked in everclear overnight, and filtered again through a coffee filter. The alcohol was then put into a glass dish and left to evaporate for a week. Water was then added to rehydrate the sticky layer of residue left on the glass. Results: Wow. Still a light dose, but actual, positive results! So, there you have it.
