I drank absinthe made with this recipe, by steeping the herbs.

heres what you need:
crock pot
1/4 inch copper tubing
1 gallon milk jug
2 large glass jars (something that will hold at least 2 or more liters, depending on how strong you want to make it)
2 bottles of everclear or wine spirits (170+proof, the purer the better)
1 once wormwood
2 grams calamis
30 grams anise seed
10 grams anise (or star anise, for flavor...the seed contributes to the psychoactivity)
25 grams fennel seed
3-4 grams coriander seed
8-9 grams hyssop
6 grams lemon balm
8-9 grams hyssop
i also heard of using red mulberry....

crush all the herbs as much as possible, the more surface area the better
wet them a little with pure water
pour just enough alcohol to cover the herbs, and shake it up. Let sit (in a warm, dark place) for 3 days to a week shaking once a day or more. Then strain it into the other jar and squeeze all the liquid out of the herbage. Pour more alcohol over the herbs, and repeat the process adding a little water on the last day. I have heard of people using half water and half alcohol, but this seems counter productive.(you do want to dilute partially when you drink it though, via the sugar cube method)
Repeat this until all the alcohol is used, and then combine both jars in the crock pot, which you have made into a still passing the tubing from the crock pot lid through the milk jug filled with ice, and then into your jar. I am out of time, you can find DIY distillation methods that are relatively safe (AT LOW TEMPERATURES) all over the web. You will have to refill the ice after about a quart passes through Let the final mixture sit for about a week, to increase the color, add a little fresh wormwood and liqurice root in while doing this. Drink up and enjoy!!
