Hi there! Not sure where you are currently located but, there is a store called Saje, that makes a lot of wonderful aromatherapy remedies. They have an online store as well that would be worth checking out if there’s not a shop in your town. They have special blends for all of the ailments you’ve mentioned ( Jet lag blend called arrive revived, headache blend called peppermint halo, PMS blend called moon cycle). I have used almost all of their products over the year and think they are great! Enjoy your trip Down Under!
