You can make alcohol from anise seeds, although I don't see why you wouldn't go buy some instead of painfully manufacture it in the back of your garage.
There must be some other products, but I don't know them.
I can't tell you how (it's against the rules), but anise seeds contain anethole IIRC and that can be made into PMA, PMMA, PMEA, or 3-(Cl,Br,or I)-4-MeO-(meth/eth)amphetamine.
Asking how to make drugs is not considered harm reduction, sorry. Also I am not aware of any drugs made from anise that have any recreational value aside from it being used as a flavouring in alcoholic liquers. We don't allow synthesis discussion if there are any anise-derived drugs that required some kind of synth. If you have a specific question that you feel really is relevant to HR and is not related to synth please PM me. For now I am closing this.
