Carrot soup makes an effective remedy for diarrhea and is easily digestible for those suffering from stomach and intestinal problems. Carrot is also useful for preventing putrefaction of the intestine and for gastro-intestinal catarrh. The carrot's potassium salt content accounts for its diuretic action, and it contains an essential oil that is effective against roundworms (eat 2 to 3 raw carrots per day for several days).
