Hello!
I have a little home cactus garden with 20-30 species. My favourite is a 10yr old Lophophora williamsii. I also have Opuntia ficus indica, aloe vera, different epiphyllums...
For the opuntia - I know that the fruits are aphrodisiac, but only in large doses and not really psychoactive, just tickling and funny.
For epiphyllum I have read that the leaves are sometimes added to ayahuasca.
Does anyone have more information/expirience with epis?

P. S. Forgot to mention, that I am a physicist (atmospheric physics) and you can ask me, I will try to answer every light- or weather- related question.
