It all gets very complicated so I don't get too into it: I'm no chemist. I wouldn't know a turpene from a turnip tbh.

We recycle our alcohol solvent. We make it ourselves so if we lose any during the oil-making process, we just top it up.

Yes, we also make oil from the leaves just like you do - we also use it topically. We dilute the rso with coconut oil, too.

Do let me know if you have a favourite cookie recipe - I do basic chocolate brownies. I'm not going to post about it because there's so much canna stuff on the web but recipe tips can be very useful :)
