Checking preperation method for San Pedro

[shivan]

SWIM has just gotten hold of 47,5 grams dried of San Pedro, acroding to scource this is enough for two persons.

SWIM just want to check that his preperation method is OK.

1. Dried Cactus is ground to powder.
2. A bit of lemon juice is added to a pot a water.
3. The cactus is simmers (but does not boil) for a few hours. The liquid is removed and saved. This is repeated two more times. The remaining cactus from the boil is discarded (?)
4. The cactus liquid is drunk cold over a timespan of one ½ an hour.

Any Comments for this? Does it seem like an OK method?
