wash the morning glories for sure with a tiny bit of soap and cold water,

but you cant do a water extraction of LSA without losing like 90% of your product.

you should get hawiian baby woodrose seeds, that way you dont have to chew up hundreds of tiny little seeds. just take 5 HBWR seeds and break off the dark brown fuzzy husk (this is what contains alot of the poisons that give you an upset stomach) then if you want to you can chew up the seeds and hold them under your tounge for about 20 min and keep chewing then if you feel like you can take it then just swallow the quid (chewed up plant matter)

just be sure you dont have anything to do the next day and try not to do them at night because you CANT fall asleep on LSA
