Did you know that eating nasturtium leaves takes away a sore throat. I will never have a garden without growing nasturtium leaves and everytime I feel a tickle in my throat, I pick a few leaves, wash them and chow them down. They taste a little burny, but well worth the reward of taking away a sore throat, instead of taking medication or antibiotics. Nasturtiums are a natural antibiotic. You can also make a yummy nasturtium salad with the leaves and the flowers.
