For Air Travel: Borax and Rhus Toxicodedron are highly suggested during air travel. Use Rhus Toxicodedron when you feel nauseous, vomiting coming on, and/or loss of appetite. This remedy is also good if you have a terrible, splitting headache and/or a dry mouth and throat.
For Boat Travel: Nux Vomica can be used during an extreme headache, horrible nausea, bloating and gagging. Cocculus works in situations of nausea, hatred toward food or the smell of food and the feeling you must lie down.
For Car Travel: Petroleum is a remedy used when you have continuing nausea and vomiting, stomach pain, an uncomfortable emptiness, an unsettling feeling that is further agitated with light or noise. If muscles become tense, petroleum can also help. If you experience the sweats, faintness or if your hand feels gripped by a tight band then Tabacum is the remedy for you.
