I'll put this out there. You may want to consider having her try DHEA. 25mg a day and it's cheap (GNC sells it.)
DHEA is a pre-hormone recreated by the adrenal gland. When we're stressed the adrenal gland releases more cortisol and less DHEA, when we're not stressed it's more DHEA and less cortisol.
DHEA is the pre-hormone to production of testosterone and estrogen.
The common misconception is that we naturally produce less testosterone and DHEA as we get older but some believe that stressful lives actually causes us to lose the ability to produce DHEA as we get older that we'd otherwise be able to produce throughout life.
In any case for older people in their 40s, 25mg of DHEA can restore closer to normal levels. As a result more testosterone in a woman and therefore labito.
The side affects for women can be hair grown, deepening of voice, or anything associated with testosterone therapy. It's not clear to me how common that is or if that's only when doses are too high. It's enough to me me reluctant to convince my wife to take it until she really needs it, possibly after menopause and after having DHEA levels tested. (I don't think it's necessary, yet.) Also testosterone can cause women to have more sever cramps during menstruation. That's something I learned about with high protein / low-carb diets.
I wish I could find it but I read one thing that cited a specific study that married women who took DHEA supplements reported better sexual satisfaction and higher sex drive.
Just search google for DHEA and it's affects on women's sex drive or sexual satisfaction.
Here are two to get started:

I don't know if that's going to help solve sexual interest with your wife. But knowing what I do, she has health problems that that seem to affect this and trying a DHEA for about a week could be a worthwhile thing. Of course you'd have to convince her to take it.
The best thing to do is have DHEA levels tested to know exactly where she is, eventually.
Of course I say all of this and I know what you're going to say. That she's had all of her hormone levels tested and that you already tried this. Anytime I have a suggestion it turns out you've already tried it.
As for pheromones. I've been testing for about a month and they haven't much for me on their own. The only time it seems to help is when I wear a sexual one when we're getting intimate and having sex. It seems like the sexual mones heighten the excitement for her and she becomes a little more sexually aggressive, more primal, or more sexually intense AFTER I get her going.
T-Rex explained that he wore LIIK while seducing his girlfriend, then after a few times he could just wear LIIK to turn her on.
This is now what I'm trying to do. I have LIIK, Evolve, and New Pheromone Additive and I'll consistently try each of those to see which one works best.
I figure that if I smell a certain way when she's having her best time, then she may start to associate that smell with her own desire.
