Tea from fennel seed and barley will not only stimulate appetite, but also milk flow in nursing mothers.
Cook some barley in plenty of water, strain. Bring 1 pint of barley water to a boil, add 1.5 tsp fennel seed. Let simmer for 5 minutes, the steep for exactly 20 minutes.
A cup taken by nursing mothers will stimulate milk flow, half a cup before meals stimulates appetite.
