Sure you could boil and then store. That´s basically what is done with ayahuasca.
Not sure about canning specifically because I´ve never done it, but from quick reading that link, I´d be wary of this whole ´lead and Bisphenol A´ migrating to the solution. I would do quite a few clean up steps later on to prevent any of those impurities from coming across, such as doing sodium carb washes on the solvent, precipitating with FASA/FASI, washing fumarates with acetone or IPA, etc...
