Health & Well-Being A-Z



Cucumber (Cucumis sativus) is a creeping vine that grows long fruit commonly eaten as a vegetable. The fruit, seed, and stem are used in medicine.

Cucumber seed contains fats that might help lower cholesterol. The fruit contains chemicals that might help to reduce swelling and speed up wound healing.

People use cucumber for burns, diabetes, high cholesterol, high blood pressure, osteoarthritis, wound healing, and many other conditions, but there is no good scientific evidence to support these uses.

Don't confuse cucumber with Chinese cucumber. These are not the same.
