herb recipes for oils, salves, tinctures, tea etc.

I thought it would be nice if there was a topic where we can share our recipes for herb oils, creams, salves, tinctures, tea's, and so on. If you have a good recipe that you use, it would be great if you could share it!
I'm going to do a herb-medicine course and in the near future i would like to give some recipe's aswell but right now im just getting started so it would make no sense if i just cut and paste stuff in here.
I hope you guys can suprise me and who-ever is joining this topic with some nice mixtures

Love love,
Stephanie
