My Significant Other and myself love this herb/plant!!
We tend to do two things to it, generally we've bought 50g of it and split it half and half.
One half goes into a high strength vodka (a 35cl bottle) - not a cheap version either! This was mashed about a bit and left in the fridge overnight, for two nights if you can wait! It was then strained through a sieve/muslin and the vodka split between us.
The other half goes into as sweet a red wine as you can find as it can make it quite bitter. Again, leave it to stand/seep overnight/two nights then strain and enjoy as the evening progresses. We tend to drink the vodka first to get it into our system.
The last time we did this, if I remember, I gently heated the strained wine in a pan over a low heat and added a little honey and I think cinnammon - turning it into a mulled type wine. It helped alot!!
It can get you quite trancey, and we tend to end up very lost in each other. The rest of the night is normally very, well... there's a reason we spend about £30 on 50g's of it!
The other thing that can also happen, is if you take this on friday night, as we've done, the effects can be re-felt, or re-initiated the following day if you have an alcoholic drink again. And also, to a lesser effect, the night after that too.
Hope this helps... I respectfully suggest that you should try it - at least once!
Oh, and it does tend to have *more* of an effect on the female of the species!
