You are getting your tea and herbal infusions confused. Herbal infusions are packaged like tea and enjoyed like tea, but however do not come from the tea bush and therefore are not teas. Herbal infusions are made of flowers like chamomile and hibiscus, grasses like lemongrass, barks like cinnamon, fruits like orange peel, etc.
Black tea contains the highest levels of caffeine (about 40mg per serving) but it can be decaffeinated. Most well-known ones are English Breakfast, Darjeeling (lemon OK, don’t add milk), Chai Spice, Earl Grey, Keemun (this is OK with milk or lemon but not together).
Oolong tea also contains caffeine, at 30mg per serving it is generally less than black tea. Oolong also can be decaffeinated. Most common names are China Oolong, Formosa Bay Jong (best quality are from Taiwan), Ti Kuan Yin. Don’t add milk, etc. to Oolong.
Green tea contains less caffeine than Black and Oolong -20mg per serving and can be found in decaffeinated form. Well-known names: Premium Green, Kangra Green Gunpowder, Darjeeling Green
White tea (the most rare, expensive) contains even less caffeine than green tea (15mg per serving). Again, it can be decaffeinated. Names include Mutan White, Flowery Pekoe White, White Pearls.
Herbal "tea" is naturally caffeine free, such as Chamomile, Peppermint, Lemon Blossom.
Decaffeinated tea generally has about 2mg per serving.
