I make a feel better tea with the following;
peppermint (relaxation), catnip(relaxation), sage(sore throats), orange zest(oranges are from the store. immunity booster), slippery elm(I buy this one from a local herbalist. It's for sore throats), elder flower(also bought from herbalist. it helps to reduce a fever), and lavender(relaxation).
The most important part is to not add too much lavender. It has a wonderful aroma, but is very bitter to the taste. A quarter of a teaspoon per cup is too much.
Another idea is to make massage oils. Take a clear jar or bottle with a lid and fill it 3/4 of the way full with grapeseed oil or sunflower oil. I find grapeseed oil works best, but I think it's personal preference. Then, place some broken leaves in. Again depending on preference, I crush mine by hand before tossing them in, but a friend of mine likes to chop them.
Leave it on the window sill in the sun for about a week depending on how many leaves you use and how much sun a day you get. Gently slosh it around in the jar once a day to mix up the oil so that all of the mint oils aren't stuck at the bottom. At the end of the week, run it through a cheesecloth to take out anything solid and you have a homemade massage oil.
Takes a couple of tries to get it the way you want it to be. The first massage oil I ever made was so overpoweringly strong that I called it "Meadow Suprise" because it smelled like someone smashed your face into a flower filled meadow and rubbed it in. It was pretty bad, I ended up throwing it out eventually.... I'm getting better at it, though.
