Hi there,
You can get spearmint tea from Neals Yard
http://shop.nealsyardremedies.com/in...=2134&brandID=
It comes loose though!
There are many neals yard shops around the UK but I'd phone up before going as not all of them stock spearmint.
I've been drinking it for 1 month (2 tsps twice a day) I think I'm seeing some baby hairs on my knees but early days... might just be my imagination!
If you try it let me know how you get on...
