I have indeed successfully consumed potent concentrated teas out of my freezer that were beyond 5 years old.
With ayahuasca plant teas and also some other medicine plant teas I end up with 5g worth per 50mL. 200mL containing the actives of 20g plant material in each of 10 clean Boost protein shake bottles. I do this from 200g dry plant material, for ayahuasca plants like caapi, rue, chacruna, chaliponga, MHRB and ACRB and also pain medicine flowers.
You should be good to go.
I'm a man from a place with hands and a face. Part of the heart of the human race. It illuminates. ∵ ✞ ☯ ॐ ☮ ღ Ƹ̵̡Ӝ̵̨̄Ʒ © $ ∴ Ę$ø✞ę®ȉ©
