welcome santaonacid
of the medicines you mentioned, Babul is possible but highly variable, Shikakai unlikely (contains nicotine), Irimed not known..most of these plants are not well known to modern science..Khadira maybe..
similarly canary grass and desmodium..there are very few or no known reports of people extracting these for alkaloids, it is more an area of frontier research for the adventurous..for acacias in india see this thread here
https://www.dmt-nexus.me...osts&t=23472&p=5 , as well as pages p49, 53, 80, 83, 86 of that thread..
of 'native' in india, Acacia caesia is probably the most hopeful/likely of knowns, but not very abundant
it would be safer to stay at this stage with plants known to have been used in this fashion successfully and safely..
A. confusa is naturalized in Tamil Nadu, and has been introduced (maybe a long time ago?)
and some of the Phalaris species which are abundant across the world grow there and have been used, but can vary a lot...see the thread
https://www.dmt-nexus.me...aspx?g=posts&t=16810i am always very interested these medicines, and many things, of the land of india..and plan to look further into this in the future
