Your sense of smell is heightened during pregnancy. You may be intensely attracted to some odors and strongly repelled by others. To keep the air in your home or office appealing, use an aromatic diffuser or simply place a few drops of essential oil in a bowl of water so that they can evaporate, naturally scenting the room. You can also boil a pot of water on the stove and add a few drops of your favorite essential oil to the pot.
To make a recipe effective in alleviating morning sickness and headache, use 3 drops of lavender (Lavendula officinalis or Lavendula vera) with 1 drop of peppermint (Mentha pipperita). If colds or flues are in the air, add 1 drop of eucalyptus (Eucalyptus globulus) as a preventative.
To help comfort nausea, place a cool lavender oil compress on your forehead and a warm lavender oil compress over the front of your rib cage. To make the compress, add a couple of drops of lavender oil to cool water in a sink or bowl. Soak a clean washcloth in the water, wring out and apply. Repeat with a second cloth for the warm water compress.
A deep whiff of peppermint oil will often cure nausea as will a cup of tea or honey water prepared with 1 drop of peppermint oil. Peppermint tea also works well. (Do not overuse peppermint, as it can have stimulating effects, and do not take essential oils internally on an empty stomach. It is contraindicated if you are taking homeopathic remedies.)
