Mint tea is always good
so is barley tea

I've never ried barley, but mint is great. I've also tried sassafrass,alfalfa,sasparilla root,red clover and a lot of commercial herbal teas

Earl Grey, Green, Jasmine, and White are my favs.
   I do some of the herbals depending on what sort of malaise I'm suffering at the moment.

Gunpowder, ginger, mint, femented, green, bitter, sweet, and any dried or fruit skins are all good to mix together!
I personally like orange skin (not the white bitter part), lavender, and cammomile (or however you spell that). It's good if you have insomnia. It means a good nights rest.

the main ingrediant gunpowder os made from turds err im sure theres a name for that

Now, Brit, you know that's not true.

Gunpowder is a Chinese tea that's basically "shake" or the little bits and pieces from regular black tea.

Camellia sinensis. Give me Darjeeling any day of the week, in fact I'm drinking it right now. Earl Grey (ugh!) became popular after the captain on Star Trek called it out by name, but it tastes like drinking melted tyres.

At night, of course, Sleepytime Tea.

The Japanese make a mugi cha or barley tea, which mixes barley with black tea. Umai desu!

Well I have to say that I don't like Earl Grey.  It's too fruity.  Or something.  I'd rather just have a cup of regular English breakfast tea.  By which I mean, tea from India that is called English breakfast tea.
  There's a whole bunch of wild plants that make fairly good tea.  I've only tried a few.  But actually, I have to confess that I often carry around a small box of Jasmine tea bags in my pack on a trek.  Probably my favourite tea, actually, especially out and about, as it requires no milk.
