Amateur aromatherapy has been a part of my life for nearly twenty years. I go through phases of using it regularly, and phases of leaving it all in a box on a shelf, but I always come back to it.
When I was pregnant I switched my attention to the safe, calming and relaxing oils. Lavender at first, and then further into my pregnancies I used geranium and clary sage oils too. Both geranium and clary sage oils are very good for any problems to do with a woman's hormones or reproductive system. Painful periods and menopausal hot flushes are both very much soothed by geranium oil.
I had grand plans for various complicated and useful oil blends while I was in labour, but both times I ended up with just lavender oil - getting rather obsessed with it though and demanding imperiously that the oil burner be topped up, or that someone warm up my lavender wheat cushion in the microwave again, while I sucked manically on the gas and air canister.
When the children were young, and in that phase of endless teething, coughs, ear infections and poor sleeping I started to investigate oils that were suitable to use with very small children. Lavender and chamomile were the two oils that got me through these years. Chamomile is a very drowsy-making oil, and just one drop, together with one drop of lavender, on a cotton wool ball placed behind the radiator, would pretty much guarantee a decent night's sleep from a sickly child. We find that one drop of chamomile knocks out adults with insomnia too - it is an expensive oil, but powerful, so even a tiny bottle will last for ages.
