What is Water Therapy?
    Drinking 1.5 liters of water daily first thing in the morning is water therapy. 1.5 liters is equal to 3.3 pints or 0.4 gallons of water or six and a half measuring cups (not tea-cups) of water.

Should it be drunk all at once? Drink it all at once and not throughout the day. Dont measure and drink but drink from a container that has 1.5 liters.

When should I brush my teeth while doing water therapy ?
You can brush your teeth and drink or you can rinse your mouth and drink water therapy.

Should I use plain water or Boiled water?
It is better to drink boiled and room temperature cooled water. Even better is to add slight flavors like given below. Boil 1.5 liters of water with the following herbs in very small quantities for 5 to ten minutes and allow to cool overnight. Next morning drink the flavored water. The following is the amount you need for 1.5 liters of water or 1.6 quarts of water.

Flavors to use

Boil water with 3 or 4 cumin seeds;
Boil water with ginger (half the size of peanut);
One basil leaf;
One mint leaf;
Three or four fennel seeds;
Three or four fenugreek seeds;
A tiny bit of camphor (half the size of a mustard seed);
A pinch of turmeric powder;
One or two coriander seeds;
One seed of cardamom (not one pod);
A piece of orange peel (tiny bit is enough);
Keep alternating with different flavors and enjoy water therapy. You can choose seven flavors and have one for each day. Or you can change once every ten days.

In fact, adding flavors might bring some additional benefits. These flavorings have medicinal values apart from imparting taste to water. Ginger, cumin and mint rectify indigestion problems. Ginger cures nausea and vomiting. For heart ailments one could use basil or cumin seeds too. Basil is rich in anti-oxidant chemicals. Most of these flavors have many potent phyto-chemicals and so protect the body from many diseases. These natural chemicals have been proved anti-cancerous and anti-oxidant in many scientific studies. However the additions to the water should be in   very minimal amounts. Do not do water therapy like drinking a herbal tea.

 Remember, most of these diseases are healed not with water therapy alone but in combination with the earth therapy (Diet) and/or the other four elements.
