As well as containing potassium, fennel (bulb fennel) is full of phytoestrogens. These are the natural plant hormones which help protect from the onslaught of dangerous estrogens in the environment. As a result, fennel is useful not only in helping to regulate menstruation, but also in calming PMS. It even stimulates the flow of breast milk in nursing mothers. When you buy fennel, look for the fattest stems—they have more flavour and contain more phytohormones.
