Nettle is said to be extremely beneficial for the kidneys, being useful in expelling gravel from the bladder and dissolving kidney stones. It is a powerful blood purifier that drives out toxins and metabolic wastes by stimulating the kidneys to excrete more water. Nettle tea is said to clean out the entire intestinal tract while activating the body's natural defense mechanisms.
The nettle tea will also kill and expel intestinal worms. It is helpful in the treatment of dysentery, diarrhea, hemorrhoids and inflammation of the kidneys. It is also useful in the treatment of asthma since it helps expel phlegm from the lungs.
