trying to infuse the herbs by melting sounds like a disaster IMO... but... heres a better option:
1. combine the caapi and pau and 'break it up' so it is manageable for smoking
2. go to your local grocery store and buy some 91% isopropl alcohol (70% works too but evaps slower)
3. disolve the spice in the alcohol
4. spread your herbs evenly across the bottom of a coffee mug
5. pour the spicey alcohol into the mug with the herbs. if there isnt enough liquid to submerge the herbs just pour in some fresh alcohol till it covers the herbs.
6. swirl it around for about 10 seconds and set the mug somewhere and wait at least 24 hrs.
ta-dah! changa!
"I'm creeping back to life, my nervous system all awry, I'm wearing the inside out. Look at him now, he's paler somehow, but he's coming round. He's starting to choke It's been so long since he spoke, well he can have the words right from my mouth. And with these words I can see, clear through the clouds that covered me, Just give it time then speak my name. now we can hear ourselves again" Pink Floyd- Wearing the Inside Out
