From reports in the phalaris project they get around the .2-.3% 5-Meo-DMT on certain clones and others seem to be the similar with NN-DMT. There was a paper that supported the claims of dry/fresh but the issue is only Ghosal seems to have done work on these plants in publications with a few more recent getting much lower content. I was told someone on reddit/nexus phalaris group has disproven the dry/fresh claims that was also said to occur with grasses.

The main thing I think is work should be repeatable by anyone interested. You don't need to do it every paper but with claims from 50 years ago a new study would be nice. Julian indeed is the only one that publicly claims these effects. He said he has sent tea to others with mixed results and some time he needs 100g but 50g is usually enough. Unfortunately the seeds in the market seem to be the wrong species.

I think grasses are quite interesting and I may attempt in the future but want to finish many of my projects rather than just add more.
