The tea recipe comes from a book called 'The Herb Book' by John Lust. It's actually an herbal identification guide and list of medicinal uses, and it also has information on natural dyes. The back has recipes for a few different kinds of medicinal teas, and this was one of six listed under 'insomnia'. It's actually a very old book, so I always cross-reference all of the information.

The entry for the tea reads:
Dill seed, Fennel seed, Spearmint. Mix in equal parts. Steep 1tsp in 1/2 cup water for two minutes. Sweeten with raw sugar or honey.

Since Dill seed is a little strong and I wanted a gentler action, I swapped it out for it's weaker form, dill weed. I went a little heavier on the spearmint for the menthol. I added a pinch of poppy, which is used for long-term mental and physical tiredness, and also to help induce the feeling of needing to sleep. (It makes sleep more restful, even light-sleep.) Bay laurel leaves can be used to deepen sleep, encourage vivid dreams, and alleviate stress. I tend to sweeten it with honey whenever possible because my body still seems to process it while I'm asleep.

Whenever I've used this tea blend, I find I get extremely restful sleep, and then in the morning if I do a WBTB, my chances are dramatically increased. (Probably because I had restful sleep in the cycle before.)

Which reminds me -- I had a lovely dream about wolves this morning! (I love wolves.) I think they thought I was one of the pack.
