In addition to emitting a heavenly scent, lavender has long been used as a relaxant, anti-depressant, and nerve tonic. As a tea, lavender can be effective in fighting colds and flus, stomach and bowel infections, and can aid detoxification.
If you or a friend/family member have some lavender growing in your garden, it's easy to turn that pretty plant into a therapeutic sleep aid. Alternatively your local health food store should stock dried lavender.
Cut your flowers in the morning after any dew has dried but before the sun dries out the essential oils, and cut way down the stem.
Tie the bottom of the stems together as loosely as possible in bundles, and hang upside down in a cool, dry and dark place/room for four weeks.

Break the flowers off and pop into your sachet or pouch (I use old jewellery gift bags), but if you don't have anything handy you could go Martha Stewart style and sew a little fabric pillow, or even use an old stocking.
Pop under your pillow and allow the relaxing scent to lull you into a deep and peaceful slumber. If you notice the smell fading, give the flowers a rub and squeeze through the bag to release more of the aroma.
