Many people have lingering symptoms of past colds and infections that are the culprit of the Lung system that is not fully healed or recovered. So try the following:
Use 1 cup rice to 8-10 cups water.
Rinse the rice, bring the water and rice to boil until the kernels begin to open.
Rice water is healing for the Lungs, digestion, hair and skin. I highly recommend it if I prescribe Lung herbal formula's.
Continue to boil for about 30-45 minutes and then strain out the rice.
Save the rice for later use.
Now you have rice water.
