I never tried a polar extraction with virola , but i've done the traditional water extraction and in my opinion I don't need any more other tek , snorted work's fine for me.
you can also consume it orally with Tabernaemontana , i tried this week my first time with virola orally in combination with ayhuasca , with caapi ,Brugmansia suaveolens flowers ,Brunfelsia chiricaspi leaves ,virola and Diplopterys cabrerana ,but i don't advise you i don't remember nothing about my week-end.
But Tabernaemontana is enough to make virola orally active i think the rootbark is also snorted in brazil in combo with Virola extract , maybe the best way to consume it.
maybe you can try a polar etraction but you may need to clean it with a solvent before the basification or may not, i m not sure about it.
