I started drinking green tea about 3months back and felt the difference within few weeks. I have severe problem of acidity and I observed within few week of starting drinking Organic India green tea gradually my digestion improved.
Most important thing about organic India green tea comes in wide range of flavours so you wont feel monotonous drinking same stuff.
Tulsi ginger
Jasmin
Ginger
Lemon
It comes in both tea bag and loose tea box.
Tea bag cost 7-8/- per serving and simple to use.
Organic India tea bags are easily available online and on nearby Kirana stores.
My sugesstiion try it for 2 months you will feel the difference in body metabolisom.
