I've found that eucalyptus and peppermint are great scents for helping headaches and migraines. You can also purchase oils in these scents that you can apply directly to your head for when you need to be somewhere that won't allow candles.
My favorite candle scent is vanilla or mango!
umm well vinnella is just the scent so it does not change how fast it will burn
An incense candle is a candle that when burnt gives of a nice scent. It is ceremonially and domestically.
If you remelt the unscented candle down, you can scent the Candle by using the correct measurement of Fragrance oil to scent the candle, then re-pour the candle in a container and let it sit and cool. Use 1oz of Fragrance oil per lb of wax for your candles.
Vitamins can not help with migraines, but they can help to your over health. You would need a pain reliever to help get rid of the pain of migraines.
Her favorite candle smell is rose.

There are at least 5 different types of migraines: food induced (especially related to gluten), withdrawal migraines (related to caffeine or alcohol withdrawal), weather-related migraines, scent-triggered migraines, and migraines triggered by smaller headaches.

warmth, scent, light.... stuff like that
Yes, things like witch hazel and lavender are particularly nice smelling. Essential oils will help make the candle smell beautiful and release a lovely scent
No. It just makes the wick burn slower. However, technically part of the candle is "destroyed" hence why you can smell the scent of the candle.
One of my favorite Yankee candle scents is Fireside. They retired the scent for a time and now it is back. It has been back for a year and is a very welcoming warm scent without the "sweetness" of perhaps a vanilla scent.
