I recently read the hummingbird tek for brewing ayahuasca . The author claims strong brews from 8 grams of MHRB. To me that represents at least 100mgs spice and thus about 1.25% . That is very high . I've read that extraction yields are hindered by alks binding to tannins, perhaps the massive amount of lye used in base teks breaks down the tannins and frees up a bit more dmt. Perhaps phosphoric acid can do the same?
