This style is widely considered to have originated in Spain, but as with all evolutions of dance style this itself is widely debated. The basics are the same as Traditional Style Bachata, but with added dance elements and styling from Salsa, Tango, Zouk-lambada, Ballroom etc.
Chamomile is probably one the best known herbal teas that help you sleep and promote relaxation before bed. Chamomile makes a gentle and effective sleep tea because it contains the amino acid glycine, which acts as a nerve relaxant and mild sedative.
Aside from that main benefit, some of the herbs are also good for different times of the day. For example, ginger herbal tea is very energizing and therefore is a great tea to drink first thing in the morning, whereas chamomile tea is calming and good for making you sleepy, so is good for after dinner.
