TEK - Glycerine "Tincture of Coca"

[Mr Coffee]

Hello All

SWIM previosuly mentioned in a previous thread about the possibility of a "coca butter" extract ( http://www.drugs-forum.com/forum/sho...d.php?t=102071)

Upon further consideration, SWIM is giving more and more thought to a "tincture of coca" made by soaking coca in food-grade glycerin in order to make a "Tincture of Coca" - SWIM read that Glycerin has a naturally high pH on the order of 8-10 (SWIM's only source at this point was the internet, so additional caution is required before accepting that report) - even still, SWIM feels this could be an ideal delivery medium as glycerin is reported to be readily absorbed in the mouth and underneath the tongue. Also glycerin is also widely used in the food industry so toxicity concerns are nil.

In order to reduce the required soaking time (which is perhaps on the order of 4 weeks at-room-temperature) - SWIM was wondering what is the maximum safe temperature coca can be heated before alkaloid breakdown ? SWIM read that the boiling point of glycerin is several hundred degrees C (290C) and thought the required time in the process could be shortened by applying heat for some portion of the extraction. More info on glycerin is available at wikipedia under "Glycercol"

Notice all the OH groups ?

interesting.
have you read this thread ?

ancient coca preparations / extracts from the British pharmaceutical codex

have some other coca-tincture / fluid extract from other sources as well, which were actually used, though most were design for oral rather than sublingual use. not sure how glycerin would change this, but it's worth looking into.

worth a try. as for the heat issue, it's a tricky one. below 100° is what's commonly used for tea brewing, especially in andean altitudes where water boils at 80° or so.
this should be safe. from an empirical point of view, coca tea brewed at temperatures of over 100° C is indeed weaker, so there must be some mechanism going on there.
Percolation would probably be more efficient than heat though.
