Partial Purification Protocol

DOSE:
20 seeds oral H.B. Woodrose (extract)
BODY WEIGHT: 160 lb
This will describe my second experience with LSA; the first was not a pleasant or expansive experience. 10 Morning Glory Seeds were ground in a coffee grinder, then mixed with water and consumed. This resulted in extreme nausea, with slight psychedelic experiences following roughly 2-3 hours later. My friend who accompanied me experienced the nausea w/o any desired effects whatsoever.

In an attempt to decrease the nausea and increase the desired effects of LSA, I recently completed the following procedure:

1. Remove seed coating with knife.
2. Grind finely as possible in coffee grinder.
3. Soak in non-polar solvent ~3 days (pet ether, Naphtha, white gas)
4. Filter solution through coffee filter; discard solvent and retain plant material.
5. Allow complete drying in cool, dry and dark area.
6. Put dried material in water, mix it for 20-30 minutes.
7. Consume water and plant material.

This method produced very strong effects with minimal nausea (one 5-15 minute period, no vomition). I have attempted numerous other methods, as follows:

Sublingual - no nausea, but no effects either
Full extraction (pet ether, then 100% ethanol) - no nausea or effects
Grinding & water extraction - extreme nausea, slight effects

This partial purification protocol seems to be the most efficacious and least nausea-inducing preparation method; the majority of the vomition-inducing compounds (cyanogenic glycosides) are removed via scraping and dissolution in pet ether, and the majority of LSA's are retained. Some nausea will still be present, but at a much more tolerable level.
