We use both the leaves and stems. There are several kinds of chickweed. Any will do, but the commonest is the one that often grows in un-weeded flowerpots and corners of greenhouses and walls. Again, use the whole plant, eating it raw or juicing it. B oth plants above and, indeed, any good leafy herb that is eaten raw will provide significant amounts of both vitamin C and iron.
Chickweed is also an excellent herb for itchy skin.
Simply crush some of the fresh leaves and stem and apply the juice to the itchy area. It is also a great blood cleanser, providing useful assistance to the lymphatic cleansers above. Put 4 medium-sized, chopped potatoes into a pot, cook until nearly done, then add washed nettles. Add one onion, and cook a further 5-10 minutes. Put through a blender.
