Thank you.
Syrian Rue, Water Lilly/Lotus, and Spider Plant. Syrian Rue needs another agent to be psychoactive like Acacia Bark. So I suspect the other two served this role since no Acacia was found.
After thought... They could have been eating the Acacia as a spread on foods separately. This is how they currently do it. Drink Rue tea and eat the Acacia together.
