Don't listen to these people, Boogie Man. They're just trying to keep you from the cure for what ails ya.
Go to whatever local health food store carries bulk herbs. Buy wormwood there. 1/4 oz should do. Don't buy the oil, it's too concentrated and will give you seizures. The only winged thing you'll see if you guzzle down oil of wormwood is the angels coming to take you home to Jesus. Or the other way, depending.
Mix the dry wormwood with 1/4 oz (combined) of anise and fennel seeds, crushed.
If you like some complexity, you can also get some angelica, damiana, and ginger root at the store. But those should be balanced to taste. If you're a fan of cayenne pepper, a sprinkle won't hurt either.
Add the herbs to one pint (that's two cups) of boiling water, remove from heat, and let steep 3-5 minutes.
Drink unsweetened for best effects; a teeny dribble of honey if you have a sweet tooth, but this may dampen the wormwood's vermifuge effects while heightening the strength of the menstruation it promotes.
Should the effects not be as you desire, you may also try this recipe:
To divine the face of your future lover, take dried marjoram, thyme, and wormwood, grind them to a powder and cook them gently with honey and vinegar to make a paste. Anoint your third eye center with the mix and ask three times that a vision of your lover's face be granted to you in your sleep. Wear the mixture to bed.
You may wish to use old pillowcases when you try this.
