1) Carrot Juice
A long-standing remedy for Nephritis is to drink fresh carrot juice. Make an 8 ounce glass of carrot juice, apple juice and lime drinking this three times a day on an empty stomach. The carrots, apples and lines should be fresh juiced with a juicer.
 
2) Homeopathy
Homeopathic medicines are prescribed for varying symptoms.  Two people having nephritis may get different remedies depending on how their symptoms manifest.

Cantharis vesicatoria - there is intense burning in the stomach and an aversion to drinking and eating.

3) Goldenrod Herb
Goldenrod is very useful when kidneys are inflamed and for the urinary tract in general. It relieves pain and reduces the process of infection. Steep 4 teaspoons of dried buds in a quart of hot water for 15 minutes. Drink 3 cups of this daily.
 
4) Uva Ursi
Uva Ursi, also known as bearberry, is one of the most commonly used herbs to treat a kidney infection and is used primarily when bacterial infection is involved. For it to work effectively, it is necessary to reduce the acidity of the urine and this is done by taking some bicarbonate of soda which increases the alkalinity (less acidic). Soak 3 tablespoons shredded leaves in a quart of room temperature water for six hours and drink three glasses of this each day. Also take half a teaspoon of baking soda twice a day.
