I was drinking a lot of plain water, at least 2 liters every day. After I got a magazine about tea I started to wonder why am I only drinking plain water when I could take in other useful stuff with it. So I got a simple tea making machine and I ordered some tea from Fares, one of the biggest tea brand in the country.
I bought an Echinacea tea wich is very good for the immune system. I used to take Echinacea pills and they are very good, I got rid of a cold in a few days without staying in bed. I also bought a tea designed for the health of the joints which hurt sometimes from to much use :)
Don't forget to enjoy your tea without sugar!
