What kind of blood cancer does he have? I had Hodgkins in June, 2008.
I personally didn't seek alternative treatments to chemo (though my oncologist did recommend acupuncture to help with the side effects).
My biggest fear with giving such treatments (depending on the chemo) is that your immune system is already compromised. Anything could cause a life threatening infection, and I'd be VERY concerned about introducing anything not sterilized into the body.
If you tweet, there are some high-level Hematologist/Oncologists on Twitter (such as @DrAnasYounes @DanaFarber @TeamOncology @MaverickNY) who may be able to provide their opinions.
For instance, some oncologists believe it's OK to boost white blood cells for Hodgkins. All the lymphoma specialists I saw were adamantly against it. I'd do your research before doing anything and feel really good about the decision.
If you don't already know about Imerman's Angels, I'd also recommend them for your husband and you as a caregiver. They match people with someone in a similar situation (age, cancer, etc) to help you get through the process and be a support when needed.
Best wishes to your family. I hope your ordeal is short and successful.
