Here´s the deal, my gf´s mother is a recovering alcoholic, she has had very hard drinking problems to the point where she lost everything including custody of my gf´s little sister her home etc.

The point where she tried stop drinking was when she got so ill she had to have a heart valve removed and replaced to be able to survive...

Today she is better but still suffers from hard denial of the damage she has done to people and still has relapses now and then...

We both think aya could help her be honest with her self but my gf is worried about her health and such.

I don´t know what kind of effects harmalas and dmt could have on a person with weak heart but could it be worse than occasional alcohol binges?

There is a slight increase in heart rate associated with ayahusaca. I can't say if it would be a serious problem or not. Best to consult with a doctor.

Which valve? Aortic/mitral/tricuspid/pulmonary?

Is she on warfarin?

Other medications?

Honestly i don´t know, will look it up.

what kind of medicines are dangerous combined with aya? would pure freebase dmt be more suitable?

As far as my internet knowledge goes aya with generally interact with anything that has to do with mood elevation, seritoin increase, and will probubly interect with blood pressure medications scince you blood pressure drops during an aya experience.
