i was thinking about giving it as gifts to my relatives
Well, yes and no. Yes because people here drink it more for its medicinal or herbal value. Old folks believe tea can ease certain pains or illnesses. No, cause we don't enjoy it as much as coffee, we don't really have a sort of "tea time" here.
But if you are to please the relatives especially old folk or Moms, they love their "imported" tea. Get a tea selection with a variety of flavors, they enjoy trying different tastes.
The local herbal teas are Charantia and Diabet made from bitter gourd while popular diet teas Kankunis and Biguerlai are the rage among weight loss fanatics.
