Isn't Venivel Powerfull Medicine?

Venivel is very ancient medicine we have used from the past. But now a days we not tend to use those medicines except commercially developed products. Are those product able to give you the effective results for your needs?

Venivel is very effective medicine to human immune system. It help us to keep our immune level high. As a Srilankan from the childhood we drink boiled Venivel water once a month or some times when we feel tired end of the hard working day. Next morning we had no body pain or other problems. Boiled Venivel water is bit difficult to drink because of bitterness.

If you get wounded or skin scratch due to rusted steel or other sharp edgers you can drink this boiled Venivel water without injecting tetanus toxoid. Our elders new it in pratice. New young generation avoid those medicines always pretend on western medicines. 

Dengue is a dangerous decease spread over many countries at present. Sri lankans are also suffer due to dengue virus. I think we can stop decreasing immune of human body with Venivel water and then can overcome from dengue virus.(That means boiled Venivel Water is not a medicine for dengue effected people but it will help us to prevent from dengue virus)
