What types of tea are useful when quitting smoking?

I’m about to quit smoking and I’m just currently trying to put in place a plan of action. I’ve quite smoking before so I know I can do it with will power but I’d like some physical help as well to alleviate the stress.

Does anyone know of any particular types of tea (that I can get in the UK) that would aid me? Or any other types of natural remedies that you could would be good too? Thanks in advance x
