Cucumber, that bland, not particularly attractive vegetable. What can you do with it besides add it to salads or make pickles? Quite a lot actually. Cucumbers have been cultivated for thousands of years. It is claimed they originated in India although wild cucumbers don't exist there.
    As a medicinal herb, cucumbers have a number of used. Some believe that they help reduce cholesterol and studies are being done to verify that. Cucumber is sometimes used to aid in reducing or removing kidney and bladder stones. They help to prevent and treat constipation. Even if you rarely suffer from constipation, they help to cleanse and detoxify the bowels. They help cool the body in hot weather (just add a few slices to that big glass of lemonade) and reduce heat rashes. Use the juice to treat skin irritations such as bug bites, sunburn, heat rash, mild burns, etc. The juice helps clear up skin problems and is often an ingredient in skin lotions. And don't forget the classic that we see pictured all the time in TV shows and ads for spas: cucumber slices on the eyes to reduce sore, tired, or puffy eyes. Taken internally, they help to get rid of some types of intestinal worms. Since they are low in calories, fat and starch, they are often eaten as a food to aid in loosing excess weight. They are a good source of several B vitamins as well as vitamin C. Some claim that if you drink a little to much, eating some cucumber before you go to bed will prevent you from waking with a hangover or headache. It is also claimed that you can reduce stress by breathing the steam from a pot of boiling water with a cucumber in it. Hold a slice of fresh cucumber on the roof of your mouth for 30 seconds to reduce bad breath. 
    For a cooling summer bath, add Epsom salt, cucumber slices, and a few peppermint leaves. 
    One of my favorite ways to make cucumber that is not bland is to mix diced cucumber with salsa for a side dish.

An interesting non-medical use: cucumber peel contains a chemical that repels roaches and ants. Also, putting a few slices in a shallow aluminum container such as a pie tin(uncovered) in your flower garden will repel slugs and grubs.
