I am tempted to use so many euphemisms for the female monthly cycle, but I will try to restrain myself so that nobody starts throwing rotten tomatoes at me. Cut to the chase: ideas for help with PMS:
Moodiness: Essential oils of bergamot and clary sage work to improve overall mood, keep you even-tempered, and lift the spirits.
Irritability: If you find yourself generally irritable, look into obtaining some geranium essential oil.
Depression: If you tend more towards sadness and depression, add rose essential oil to your plan.
Cramps: The clary sage essential oil you purchased to even your mood will also help with menstrual cramps when combined with lavender and/or Roman chamomile.
Stress: Lavender and Roman chamomile are also wonderful for inducing relaxation and restful sleep at the end of a hard day.
Bloating: Grapefruit and lemon essential oils work wonders for bloating, as does juniper essential oil, and these are the same oils that will be soothing to a constipated or watery digestive system.
