Dill is mostly a culinary herb today, but it does have some value in medicine, mostly as a stomach soother and anti-gas remedy.  It is also said to increase mother's milk and help treat breast congestion from nursing.  It is mild, and makes a good remedy for colic in babies. 

Dill water is used often for relief of the above symptoms, and can be made by adding 8 drops of Oil to 1 pint of water.  Take up to 8 teaspoons per day of this concoction.  Dill can also be made into a Tea, and sweetened with honey, or prepared as an infusion by steeping 2 teaspoons of seed in 1 cup of water for 10-15 minutes, then straining.  Take 1-2 cups per day.
