Should I Boil Ginseng Tea How Do I Make A Tea With Whole Ginseng Root?

How do I make a tea with whole ginseng root? - should i boil ginseng tea

I bought a whole ginseng root on the Korean supermarket today. I tea with him for use as a substitute for coffee, but I've never had this kind of tea before.

How can I use ginseng to make a cup of tea? How long should I boil water with ginseng in it? Is it ok to drink, this tea in the evening and I was better than in the morning?
