Recently in Kensington and Chelsea a bunch of us had a fun-filled couple of hours during which we discussed certain 'weeds' and their medicinal properties. We made a cream, tincture and ate some salads all of which contained useful 'weeds'.
The next time you weed your garden try a few dandelion leaves in a salad. Pick young leaves and mix with different salad leaves to introduce a zingy flavour. They are packed with vitamin C, Calcium, magnesium, potassium, sodium.
