Gertrudes said:Black tea has a (small, I think) amount of caffeine, but you can still drink herbal tea as you get closer to bed time, there's plenty of variety for herbal teas so I think you won't have a problem finding a few that you like.
Regarding spices, the ones you have mentioned aren't, as far as I'm aware, within the list of the most allergenic ingredients. Having said that, it's probably still a good idea to test each as each body is different and you might react to something apparently harmless.
Hope this helps.
So herbal tea has less caffeine than black tea and green tea? I have some herbal tea at home. I like especially chamomile before bedtime. :)
It's is good to know that those spices are not the most allergic ingredients. Thank you Gertrudes.
