If you go to the Cooking Forum and look in the top sticky at BadKittySmiles CannaPharm thread, there is a recipe in there that you can use for practically anything. You will be looking for the Hash Capsule recipe. It is important to follow each step carefully to guarantee that you end up with potent liquid gold. I have never been able to get the lecithin powder, however, and use the granules. These work fine, but need some extra time between the oven and freezer. (If you decide to go this route, let me know and I will walk you through).
Now once you have your precious liquid black gold coconut (healthy oil btw) hash oil, you are ready to get high. I have measured it out at this mixture and a 1/4 tsp = 1 dose. So for your wife's juicing, have her add accordingly, just mix it right in, starting with only 1 dose! Seriously! It behaves different with different people, so 1 dose may do it, or over-do it. It is best to err on the side of caution with edibles. Give it up to an hour or so to take effect. If 1 doesn't work, the next day she will know to try 2, and so on, until she finds what works for her.
This hash oil can also just be put into gel caps as the OP suggests. Either way, good luck.
