Unlike, Obtusifolia, where you will get a small tryptamine content out of the phyllodes from most strains, you will get 0.3-4% from the Phyllodes that is of killer quality and that you can make brews from.
Also, this goes for Acuminata on the west coast, the phyllodes contain up to 1.5%, so I hear. The bark contains more, but at these sorts of yields who is complaining when it is so much easier to take the phyllodes.
I guess people are taking the phyllodes of these species because bark has traditionally been taken because Obtusifolia phyllodes are not to be useful in SOME strains - having said that, some strains on the south coast of NSW, contain good quality tryptamines at about 0.5%.
KNOW YOUR STRAIN!
