Is this a bad gift? Christian ladies, I need your input!

Cake • It's called the American dream because you have to be asleep to believe it.
I have this friend - we've been best friends since the 3rd grade. She was never religious when we were younger. I moved away for a few years and came back to her being super Christian (specifically Baptist). It was odd, but I left a Christian and became a Witch within a few months of moving back home, so we both went through huge religious changes. It's driven us apart a little, but we're still close friends. But point being, she's getting married in September and I'm going to be one of her bridesmaids :)

With that in mind, I've found a passion for herbalism. I discovered a wonderful aphrodisiac liqueur recipe - for a super special night of romance. My friend still drinks on occasion, but I know she and her SO have been refraining from sex until marriage. So I thought this liqueur would be a great wedding gift. I'd make it once, try it out myself to make sure it's safe (and tastes good) and then I'd make one for her as a wedding gift. There wouldn't be any rituals or Witchcraft involved in it - all it really is is various herbs, vodka, rose water, spring water and chocolate. 
But she knows I'm a Witch and really doesn't agree with it, so even though there isn't any Witchcraft going in to the gift, I'm not sure if she'd like it considering the nature of it and the fact that I (a witch) made it.

What do you think? If you were in her situation would you even want something like this? Or should I just think of something else? I can't just ask her cuz I want it to be a surprise :/
