Naval mara kuvalai / Jamuntree Tumbler / Jambolan

This is carved in the base of the Jamun tree. This is having huge medicinal benefits.  Good for patients suffering from Diabetics, Obesity, High BP, Joint pains, etc.

Method of Usage;

• Fill the water inside the tumbler at night and drink it morning on an empty stomach, fill the water again and keep it to drink at night before going to sleep.
• Water poured inside will take the slight color of “Naval” (Jamun) in 6 hrs, which shows that water is ready to drink. When the water remains as same (which happens in 15 to 20 days)  Just rub the inner area of the tumbler with a small knife to peel out a small layer, so next time the water will get in contact with the new surface thus extracting the medicinal values from the wood.
• In case, it gets broken or started leaking, just put the wood inside a vessel, pour water inside the vessel for obtaining the same results. 
• One Tumbler can be effectively used for 1 year.
