Alfrendo has a question about making changa from virola resin. He believes this procedure will work:

Powderize dry virola resin.
add sodium carbonate to virola resin 1:4 ratio.
add enough water to make a paste.
evaporate water, chop/powderize, dry further to ensure no water.
Mix in warm heptane or naptha, stir vigorously.
filter solution, keeping fluid.
add smoking herb to fluid, Alfrendo chooses pau d'arco and mullein
--it is possible to add harmalas at the same time as the herbs
dry/evaporate fluid, mixing occasionally.
when no naptha/heptane odor remains, test small amount and build up to gauge potency.

Does this sound like a good method? Alfrendo will probably use virola calophylla to obtain a mostly DMT product. He may do this procedure on some virola theo. but not include the herbs and use the resulting powder sublingually or orally
