Preferably able to obtain a phytosanitary certificate from their local plant quarantine or agriculture office. I'd rather deal with Indian sellers for this one versus Thai sellers - no offence meant just need the authentic seeds. EU studies show it's good for epilepsy and other seizure / involuntary spasms (lewey bodies dementia , Parkinson's etc) not as medicine itself but as a complementary supplement, pref taken as tea so will be needing to plant some.
PM please, thank you!
