Radishes assist in respiratory disorders, brochitis and asthma. It relieves congestion of the respiratory system including nose, throat, wind-pipe and lungs, due to cold, infection and allergies. It is a good disinfectant and also rich in vitamins, which protect the respiratory system from infections. Radishes also give you a significant amount of vitamin C to boost your defences against disease, they regulate your metabolism, improve blood circulation, and are a good treatment for constipation, headaches, nausea and gall bladder stones. Since we generally eat radishes raw, we benefit from this nutritional benefit as these compounds are depleted by cooking. Pop them in your mouth for a juicy crunch with a kick of mustardy heat.
