Thanks Water! The second link was very helpful. Uny said that she put the oil back in the dehydrator to "tincture" for two more weeks but she didn't say at what temp. Uny, can you tell me what temp (I guess the same?) and also, what is the original herb to oil ratio? And finally, with catnip, should I use dried or can I use fresh? I couldn't tell from the first link.
