These were known as 'Granny's Herbals'  when we were growing up,  because my granny always had a packet in her handbag.   And they haven't changed a bit.   The delicious natural herbal flavouring is both soothing and refreshing. 
Described as 'A Working Man's Friend on cold nights and mornings', we'd argue that they're equally appropriate for women on hot summers' days.
