Phalaris contains toxic compound that should not be ingested (gramine).
Actually i didn't saw a procedure for extractions / separation of goods in phalaris.
Consuming acidic tea could be very bad if ph is very low, think to your stomach !
In general way, never consume a plant that you're not familiar with, that you don't know what is it.
You should read documentation on erowid concerning this plant
https://erowid.org/plant...ris/phalaris_info2.shtmlIt says there was some effects...
Take care
