last summer i mixed extracted mescaline hcl with harmalas on several ocassions. Its a very nice combo, and safe imho. No admixtures, usually just 100-150mg of extracted rue, or a dose of caapi that would be half of what i would need for aya.
As for the mescaline, it was usually under 250mg. The harmalas will potentiate it to a fairly good degree, so be careful and start low, if you add an admixture or extracted dmt to the mix be extra careful.
As far as interactions go between the mesc and harmalas, i did not notice anything out of the ordinary, or toxic feeling, but it is a phenethylamine, so ymmv.

In a society in which nearly everybody is dominated by somebody else's mind or by a disembodied mind, it becomes increasingly difficult to learn the truth about the activities of governments and corporations, about the quality or value of products, or about the health of one's own place and economy.
In such a society, also, our private economies will depend less upon the private ownership of real, usable property, and more upon property that is institutional and abstract, beyond individual control, such as money, insurance policies, certificates of deposit, stocks, etc. And as our private economies become more abstract, the mutual, free helps and pleasures of family and community life will be supplanted by a kind of displaced citizenship and by commerce with impersonal and self-interested suppliers...
The great enemy of freedom is the alignment of political power with wealth. This alignment destroys the commonwealth - that is, the natural wealth of localities and the local economies of household, neighborhood, and community - and so destroys democracy, of which the commonwealth is the foundation and practical means.” - Wendell Berry
