Right this is what I do.
1) Get Some seeds
2) Put them in a coffee grinder and grind them really fine.
3) Put them in a 1/3 concetrated lemon juice and 2/3 nearly boiling water.
4) let it sit in there overnight. stirring occasionally and/or occasionally heating the water a bit to fairly hot but not boiling.
5) strain with a old t shirt.
6) drink the water and chuck the seeds away. All the alkaloids should have gone into the water.
