A pure lavender oil is too bad, in order to refresh or take softener to drip a drop in the final rinse cycle of the washing machine only Lavendelkissen.
In aromatherapy lavender is a jack of all trades, because some substances of plant with nervous tension or insomnia calm / balance, encourage others in fatigue and refresh.
My standard recipes from Hobbythekbüchern:
Medicinal plants oil for coughs
-------------------------------
1 drop lavender oil
2 Tr peppermint oil
1 Tr tea tree oil
1 Tr thyme oil
(In addition expectorant are rosemary, and peppermint Eucalypthus)
Massage oil, relaxing
---------------------------
80-100ml soy, almond or jojoba oil
12 Tr rosemary oil
12 Tr geranium
12 Tr lavender oil - start at the first attempt with less lavender, because the smell is very intense.
