HELP Flavour and tea
 

I have blended several types of teas to enjoy different tastings and
having fun .Its a tea party , and now have decided to spray the leaves
with the different flavours available like mango raspberry etc.
Can anyone guide me or help me with this process.
1 What is the carrier for the flavour, I have seen oil based and
alchol based what tdo the big companies use?
2 natuarl and natural identical
3 what is the right leaf to spray
4 how do you go about spraying the leaves
If anyone has some good experience with this I would be very happy if
you would be kind enough to enlighten me on this as I really would
like to have a bit of fun
Thanks
